The PT 11 and Spear are very dependent on gaskets. The 11 has a hull gasket, a hatch gasket, and a trunk cap gasket. The Spear has two hatch gaskets and a trunk cap gasket.
We are fairly proud of the gasket systems we have developed, but nothing is ever perfect. The latex tubing gaskets set in notches of the correct depth work amazingly well, but we have had some trouble with two things:
One of the issues is that gluing the latex gaskets is difficult, so they can come loose.
We have tried just about every adhesive and have finally found one that works much better than the contact cement method described in the manual. More about that in a soon-to-come blog post.
The other thing we have recently had happen is the outer face of the gaskets becoming stuck to their mating surfaces. This seems to be a problem mostly with the trunk cap, where the gasket is pressed much more firmly, due to the gasket notch depth being limited. We tried coating the outer face of the gasket with a few different lubricants, Vaseline being the one that seemed to work.
We will do a blog post about gluing in new gaskets with the adhesive we have found to work, but first we would like feedback on gasket issues from our customers. -What issues have you had?
-Do you need a new set of gaskets for you boat?
-If your gaskets are working fine, consider rubbing a light coat of Vaseline (or maybe you know of something that will work better) on the outer face of the gaskets, especially if your boat is being left assembled for long periods of time.
This September we had the opportunity to play with an EP Carry electric motor for the first time. Dinghy owners often ask about an outboard for the PT 11.
Our preference is to discourage outboards on our dinghies because good rowing and sailing boats never make great motor boats. But some people really want to be able to use an outboard. That's understandable, but the fact is that the smallest gas outboard motors currently available are really too big for our boat; too much power and too heavy.
Now there is an option we can support; the EP CARRY electric "outboard". All of the technical information about this innovative little motor can be found on the website ELECTRICPADDLE.COM. Though it is compared to a 1HP on their website, it has sufficient power to get the PT 11 up to a cruising speed of about 4 knots. The USCG however, considers all small electric outboards as "2HP". Based on that formula, the PT 11 and PT Spear are rated for "2HP" so, the EP CARRY aligns with the Coast Guard figures. The amazing thing about this motor is that it weighs only 14.4 Lbs. This makes it very easy to mount and remove. The battery pack weighs 6.3 Lbs, making the total package less than 21 Lbs. There are several design features that add to the ease of handling as well.
(At this years wooden boat festival, Russell showed up with the motor in his bicycle bag.)
Our recent experience with the EP Carry was very positive and to my surprise, I caught Russell grinning after speeding off to visit other boats in the anchorage. "Mr. anti-outboard" was actually having fun and we enjoyed it further by taking a friend on an evening "cocktail" tour of Reid Harbor, a deep bay with lots of shoreline and many boats to observe.
We spent a couple of days, driving along the shore of Sucia in the San Juans, in Shallow Bay making watery doughnuts, backing up, going forward, generally goofing off, and then venturing out to 'Danger Reef' to "brave" close proximity to a group of Stellar Sea Lions. We were pleasantly surprised by how far the battery went on one charge. You will notice in our video that we carried our oars with us but we did not need to employ them.
This motor is not silent. Neither is it loud. Our lightly built plywood boat seemed to acoustically amplify the sound a little. Even so, there was no need to raise our voices for conversation. In fact, we could almost whisper and still communicate. This was a plus to me. Loud outboards in quiet anchorages are, in my mind, a real nuisance and many of us are familiar with boaters talking in their loud dinghies barely hearing each other and assuming no one else can hear them either...but of course we hear every word. Sound is a funny thing. With the EP Carry, the birds, seals, and sea lions were undisturbed by our passage. It made it a great modus for exploring the nature around us.
Another thing that is really attractive to us about this motor, is that even with our limited house battery power, we could re-charge the EP Carry Battery. It does require a 150-200W inverter, but this lithium battery requires a third of the power than comparable models to recharge. At home, it is simple to plug it into a normal outlet. Beyond charging the battery and rinsing the unit after use in salt water, there is virtually no maintenance. Yet another plus.
(see our video exploring Sucia with the EP CARRY)
When our EP Carry arrived at the door, unpacking it was quite amazing. The care taken to pack it and the detailed contents made for a well thought out and complete package. It was a positive reflection of Joe and Linda who have spent years perfecting their product. They, like us, had a vision that they worked and reworked in every detail. In fact, the original mount did not fit the PT 11 and now it does. Further, the EP Carry, designed right here in WA State, is assembled in the USA. It is yet another example of admirable American ingenuity with style and a small business making a positive difference in the world. Of all the outboards on the market, we feel confident that the EP Carry is a good fit for the PT 11.
The new batch of plywood is BEAUTIFUL and kits are rolling off the CNC machine.
Out of this batch of PT11 ans PT Spear kits, everything is beautiful, except....one PT11 foredeck. As it is not cost efficient to cut just one new foredeck, we are offering this kit with a $50 discount. See the photo below to better understand this somewhat deep but pretty small flaw. (smaller that a quarter) Anyone want to try their hand at an inlay repair?
Our mahogany riser blocks of the past were beautiful complex shapes that performed a nicely functional duty; to give the oarlock socket more bearing and to offset the height of the seat relative to the height of the oarlocks. They were, however, rather beastly to make in the quantities we have been needing.
To improve production, Russell took the design to Turnpoint Design and figured out how, with minor changes, they could be machined on the CNC router. The remaining labor, (sanding out the tooling marks and rounding the upper edges ) is a great deal less time consuming than the previous version.
They are still made out of Sapele Mahogany. For those of you who wanted riser blocks this Fall when they were not available, this is our new product. Please let us know what you think. We have them IN STOCK! 😉 AEB
It’s time for us to admit it, our boats seem have a weakness. We may just be treating our boats poorly, but it’s more likely that there is an issue that PT 11 owners should be aware of.
Owners, please check your gunwales for cracks.
Builders, there will soon be an added step in the building manual to prevent the problem. If you haven't glued your bumper on yet, the fix is easy. This printable PDF informs for both a fix or the added step in the build process.
We have seen this failure three times now. The first, when one of our boats got driven over (just the edge) by a truck. We thought that was unusual punishment, fixed the boat and forgot about it.
The second time was a boat that got beat up by solid water while lashed to a foredeck. We didn’t really know what happened there.
The third time it happened, it was our newest PT 11 (3 years old now) and again we don’t know exactly why, but here is our theory:
When the boat is upside down in the nested position and somebody walks on it (or a bunch of people sit on it), where does that weight go? It goes onto the very ends of the gunwales on the fwd hull half.
The failures we have seen have always been in the plywood hull skin (right where you would expect it).
Fixing the break and the weakness that caused the break are both pretty easy and important. The first is done by injecting epoxy into a carefully drilled hole to fix the crack, the second by putting screws (with epoxy) into carefully drilled holes.
I admire those who take on the challenge of building a boat or an airplane. CNC technology on kits has done for creative people, what the GPS did for adventurous people. (Not that they might not be one and the same) Cruising is far more accessible to those without traditional navigational skills, and CNC routering has opened up a whole new avenue to those who want to create something that would otherwise have been beyond their skill level.
Pause on that thought while mentally revisiting a lot of fun sailing..... OK-back to the present.
Our customers come from many walks of life and a wide range of ages and skill levels. However; they never fail to impress me. While Russell can take credit for creating a beautiful design, kit and manual, our customers need the vision, passion, patience, and attention to detail for good results. To add the complexity of documenting their own efforts takes the same qualities and much more. I cannot, for example, count how many tens of thousands of photos Russell had to carefully set up, snap, choose, and edit to get a few hundred for the manual.
Hence, for this post, I would like to point the spotlight on the Kerr Family; Randy, Kim, son Alex, and good friend Mark. Not only did they complete their beautifully built PT 11, "Lil' Bear" in about 6 weeks, their documentation of the experience resulted in a wonderful
and creative little video. The feedback from Kim and her family has been so meaningful to us and I feel puffed up with pride like a mother hen. With their permission I am sharing some of that feedback and the wonderful present of this video. Randy's videos are all beautifully created and fun to watch so explore and let them know what you think.
From Kim, "It was your PT11 kit that made my dream of having a sailboat come true!!!!! Randy and I can’t quit talking about how grateful we are that you guys put so much heart and thought into such a beautiful and smart kit. She sails and rows like a dream! Highlight of our summer to build and sail that boat! So thankful for you and Russell."
Yes, there are some crazy things happening in our country and in the world. I refuse, however, to let that overshadow all of the wonderful things and people that, through shear existence and positive attitudes, are in some way, making this world a better place, cherishing what is good and beautiful. Thank you to the Kerr family and all of our customers for your inspiration. AEB 😉
Yesterday morning began with a tropical downpour that is just as out of character for the PNW as this summer's 90 degree temperatures. A few days ago the driveway was suddenly littered with crunchy yellow alder leaves. It has hit me hard that summer is coming to an end. For us, it also means that our local Wooden Boat Festival, (the 40th!) is upon us. We will be there! September 9, 10, & 11.
We are pleased to announce that two, customer built PT Skiffs to be at the festival this year!
Mojo at the Wooden Boat Festival
Immediately prior to festival, we will be in Deer Harbor (Wooden Boat Rendezvous), and just as promptly after festival, we will set sail northward, incommunicado, for 2 weeks.
We try to go sailing every year after festival and this year is special as it will be our first trip in our 'new' boat. We have yet to give it a name and perhaps this first real sail on her will help us decide on a name from our list, many suggested by friends.
If you are curious about our odd but inspired cruising boat, a G-32, the original promo videos can be seen HERE, and Russell's refit blog HERE.
We will have the PT 11 with us as we travel up to Desolation Sound and back. During that 2 weeks we will aim to get new video, recharge our creative and productive energy banks and be on full power for our busier Biz season; Fall through Spring. Hence, we will be a little difficult to reach by phone and a little slow to respond to emails for the rest of September, but please write and leave messages anyway! We will get back to you and new production favors the early birds. There is also the quick deposit button if you are ready to secure your place in line for kits while we are away.
While I am at it, I want to share a couple of pictures of some dinghy fun from this summer. It is exciting for me to realize that quite a few PT 11's and PT Spears have been completed locally and regionally (with many more on the way!). We had our first 'mini regatta' of friends at Watmough Bay this summer and look forward to having more PT 11 'meets' in the future.I also have this vision of a Wooden Boat Festival here, perhaps the 41st next year, where-in a veritable fleet of PT 11's and Spears fills the foreground of the sail-by on Sunday afternoon, escorted of course, by several PT Skiffs.... my how our family is growing. Mark it on your calendars if you think you can make it. 😉 AEB
Fun! For the second year we had a blast in our PT 11 as the smallest entrant in the Shipwright's Regatta hosted by the Port Townsend Sailing Association. Russell was at the helm and I was ballast, chocolate dispenser, and "kite" handler, .... hmmmm... maybe we have some work to do if we are going to get real about racing...
Of course Russell would have been much faster by himself but no fun without me! Kidding aside, we didn't do all that bad (13th out of 19 boats in Class B) since our competition was all multiples of us in waterline. (except for Simeon in Noddy, his SCAMP)
It was a beautiful day, perfect breeze, sunshine, and little chop. I took some photos and Ace managed to capture a shot of our "kite" on the down wind leg... yes, it really was a kite. I could not get it out from behind the mainsail but it actually did have some pull to it. The one time I got it up higher, it nose dived into the water and became an instant drogue. A funny experiment that confirmed we could come up with an 'itty bitty' spinnaker and make use of it. We shall see...
Oddly, for Russell and I, it takes more discipline to actually get it together to participate in our local sailing events than to work in the shop and office every day! Gotta work on that... 😉 AEB
What is different about kits from PT Watercraft and why do they cost what they do?
To start, we produce the kind of kit that we would like ourselves, something more advanced. Advanced from the perspective of functionality, performance, longevity, and good strength to weight ratio, etc.
This approach seems to be working as our nesting dinghy kits (our most complex kit) has been selling very well.
Most kit companies avoid hand-made parts when possible, and for good reason; they take a lot of time to produce and they increase the cost of the kits.
How can we afford to have so many custom and hand-made parts in our kits? Because we have no real employees and a very low overhead. This can be limiting in some ways, but it does afford us the ability to to really focus on each and every part that goes into a kit.
Development and manufacturing has been a lifelong interest. Figuring out new, more efficient ways to produce parts is fun for us, so we thought we would share a bit of it with you.
Even though there are 5 different thicknesses of plywood in a PT 11 kit, the 6mm plywood parts (shown below) form most of the hull, foredeck, transom, etc.
There’s no handwork here; all these parts are cut by a very good CNC operator (Turn Point Design). There is however, much effort that goes into buying and grading this plywood. We reject unattractive or warped sheets and pick the best looking sheets for cutting the foredecks, buoyancy tanks, etc.
We are lucky to have Edensaw Woods, a very large plywood importer right here in Port Townsend, yet finding good (and good-looking) plywood has become both more expensive and more difficult. When we find what we want, be buy a lot of it.
The 6mm parts are the first parts to go in the crate. We use a 5 page “map” to show how the layers nest to take up the least space and yet lay flat in the crate.The main connective bulkheads (12 mm plywood) are also CNC cut with scribed marks for locating doublers, gussets, and trunk. The forward of these two bulkheads has a notch for the hull gasket, which unfortunately needs to be on the opposite face as the scribed marks, so CNC cutting the notch is not easily done. We very carefully cut the notches with a jig and router as shown below.
The large gussets, visible in most PT 11 photos, are what really tie the front and back halves of the boat together (and help us sleep at night).
There are 8 of them per boat (complete set in foreground of photo below) and they are made from 25mm (1”) thick plywood. Being so large (and thick) makes them both very effective at taking the loads and also relatively easy to install in the building process.
For the first couple of years of selling kits for this boat, we asked the builder do the handwork on these parts which, without the right tools could be difficult and potentially dangerous.
The upper gussets (right hand cluster in the foreground below) are heavily beveled on the outboard edges to match the angle of the hull. We do this with a large 1 hp tilt-table disk sander hooked up to a large vacuum.
The appropriate edges are then rounded on the router table, which is far safer and easier than the builder rounding them with a router by hand.
There are only 3 different gusset profiles when we start the handwork part, but when we finish beveling and rounding edges, there are 6 different parts. In other words, it’s critical to bevel and round the right edges and pack the right parts.
The machined gunwales (also made from 25mm plywood) don’t require handwork, (besides checking the joints and packing), but they do a very effective job.
Not only are these gunwales easy to join and install, but they lock the upper edge of the hull into its designed shape without having to laminate the gunwales and without needing much framing to support the upper hull panels (see photo).
The outer faces of the gunwales are “capped” with unidirectional glass to make them very strong for their weight before gluing on the bumper.
Making gunwales from plywood was not an inexpensive route for us to follow (we are the only kit company currently doing this) but the result has been worth it.
The lumber kit unfortunately ends up hidden under the foredeck (mostly) in a finished boat. Unfortunate, because we use high grade Sitka spruce that no one but the builder gets to see.
We use Sitka spruce to keep the parts light and strong.
The foredeck stringers (the biggest of these parts) let us keep the foredeck thin and light, yet stiff and strong enough to be walked on.Joining the foredeck to the hull are machined 15mm plywood glue cleats. These are machined to the curve of the foredeck edge to make them easy to install and pre-beveled to fit the angle between hull & deck.
Our trunk logs (the spacers that separate the daggerboard trunk walls) are cut on the table saw from pre-fiberglassed stock.
Why do we pre-glass?, because if the builder were to glass these pieces it would be difficult to keep the edges square when trimming the glass. Square trunk logs help make square trunks, which helps the dagger board fit into the trunk, etc.Making our own mast sockets is necessary because the masts that we use are an odd outside diameter and the mast must fit into the socket without a lot of wiggle room.
We found a steel tube the right diameter (after much searching) and use this as a mandril to make tubes long enough for 5 sockets to be cut from.
How we actually make these tubes is more than we want to show, but how we get the tubes off the mandril is interesting: The mandril is covered with adhesive-backed Teflon film (small photo), so after the tube has been laminated and post-cured (with heat), the tube is pulled off the mandril with a come-along.
We used to do this between the shop truck and a tree (it takes a lot of pulling), but now have found that we can put clamps over the ends of a 2” thick plank and pull from those as shown.This photo shows the mast step assembly placed on the mast step bulkhead. These parts are easy to install (if one follows the manual) and easy to install accurately as there are scribed centerline marks on all the parts.
All bulkheads have tongues (visible in this photo) that fit into slots machined into the hull panels.How we make the alignment clips is also more than we want to show, but they are really a lot of work to make. We almost cry when it’s time to make more of them.
They are molded from many layers of carbon in a long blank and then cut into the shapes shown.The alignment clips are part of the joining system. They automatically (when pushing down on the forward hull-half), align and hold the two halves so that the threaded pins can find their sockets.
The alignment clips seat over small strips of filled epoxy (photo on left) that are glued to the bulkhead edges and then shaped level with the foredeck, where the clips are attached.
At the heart of the PT 11 is the connective hardware. This hardware has evolved considerably since our early prototypes.
Designed by Russell Brown and Paul Zeuche, this hardware (4 sets per boat) is very strong, easy to use, and maintenance-free.
Paul Zeuche machines these parts from 316 stainless steel and does so with a lot of care and pride.
We assemble these parts with the knobs and the custom beveled cap nuts and check tolerances, etc.
The knobs (star knobs, we call them), are machined from G-10 fiberglass plate.
This is a very dense and strong (similar to aluminum) epoxy and glass material that machines well and doesn’t corrode.
Unfortunately, G-10 is no longer available in black, but since the builder has to sand and coat the knobs anyway, they can just as easily be painted instead, even with enamel paint in a rattle can.
These are cut by the CNC machine, but we chamfer the edges on the router table and tap (thread) the holes.
Also made from G-10 plate are the wear strips that are used at the upper and lower ends of the dagger board trunk.
Our method is a very effective and easy way to seal and toughen these damage-prone edges.
The towing hole is a piece of G-10 tubing that is bonded into the cutwater area of the stem.
A towing point should be strong enough to yank hard on the boat when it is full of water and this one is.
The PT 11 is covered in fiberglass cloth on every exterior surface (including the inside).
Glassing inside and out gives the boat a very long potential life span and it’s not hard to do.
The method we use is to pre- fiberglass and sand all inside surfaces with light cloth before assembling the hull, while the parts are laid flat on the table.
The outside of the hull is glassed with heavier cloth after assembly, and the bottom of the hull is glassed with even heavier cloth yet.
This takes a lot of cloth and three weights of cloth...And there’s peel ply for the chine taping.
The fiberglass types and weights used on the PT 11 are carefully chosen to make the boat as light and strong as possible.
Unidirectional fiberglass (additional to the 3 types mentioned) is used on the outside faces of the gunwales to dramatically stiffen and strengthen them.
We carefully roll the cloth onto tubes on our 24’ long cutting table.
The parts you have seen in this article are base kit parts. Several parts included in the kit are not shown here. See the kit contents photos.
In 2016, some of the parts that have previously been options will be included in the base kit.
The PT 11 (and Spear) foils are not the usual dinghy fare. Good foils are just as important as good sails if you want performance, especially upwind. Again, we went for something that we would want ourselves.
Sailing adventures on our multiple PT 11 prototypes while cruising have provided some of the highlights of our trips. Having a dinghy that really performs, especially upwind, makes it possible to explore farther and it is definitely more fun.
The accurate foil shape (NACA 0012 section) and high aspect ratio are what makes these CNC machined foils perform so well.
Machining them from plywood (instead of making them from fiberglass in a mold) is more affordable and there’s not a huge amount of labor involved in going from the kit to finished foils. The result can be really beautiful and tough foils that are lighter than most molded dinghy foils.
Unfortunately, the Okoume plywood industry has recently moved to using thicker veneers in thick plywood panels, so instead of the foils being made from 9 ply (12mm), they are now made from 7 plies.
The foils are machined in halves (photo below) and bonded together with vacuum pressure so there are actually 14 plies in a foil that is almost 1” thick.
Machining foils from plywood is the ultimate way to find defects hidden within the layers. All of our foils have some visual defects or slight waves in the veneer lines, but sometimes a whole batch of foils will become “paint grade” foils sold at a discount.
From one 4’x8’ sheet of plywood we can machine 12 foil halves, which sounds like a lot, but that makes only 6 foils, enough for 3 boats.
Vacuum bagging the halves together is a laborious process, mostly because the parts have to be held straight when being joined, but we have a new method to try, which could be better.
The machined surfaces of the foils are very accurate and fair, but we sand out the tooling marks after the halves are bonded together. We sand just until the tooling marks start to disappear, and then sand the edges and round the upper (rectangular) parts on the router table.The design of the foils parts is something we are proud of. The kick-up rudder is simple yet can be locked down or up and can be folded back to fit in a foils case.
The gudgeons are modified (by us) to be the right width for our rudder case and there are scribed marks machined into the case walls to show gudgeon location.
The tiller and hiking stick are Sapele mahogany. The tiller is tapered on three sides in a router jig and the holes drilled in drill press jigs, leaving just the edge rounding to the builder.
The rigs are an entirely different kind of work for us. The wonderfully lightweight two-piece carbon masts come to us through the windsurfing industry, but we do a large modification to the bottom ends of them to make them strong enough to be socket-stepped.
The boom tubes are made for us by ICE and they are so lightweight that adding the Harken and Ronstan hardware to the booms just about doubles their weight.
We build the rigs complete. They are ready to use when they leave the shop.
Having grown up dinghy sailing (from a cruising boat mostly), I knew that for our rigs to be successful, they had to extremely easy to use. Carbon fiber spars make it possible for us to build a 13 pound rig. That’s 13 pounds for the mast, boom, sail, running rigging, and the bag that it all fits into.
Set-up and break-down of this rig is fast and easy enough to make a “quick sail” something that one actually does, instead of just thinking about doing it.Like everything else we do, we try to build a lot of rigs at one time. Shown here are 10 rigs worth of spars. The upper mast sections (far right of photo) are the only part that isn’t much work.
The fatter sections are the lower ends of the masts, where all the hidden reinforcement happens.
On the left are 10 booms just started, with only the gooseneck fittings attached.This kind of work can be stressful, as mistakes would be very costly (the tubes are expensive), but also quite rewarding. The process is refined with every batch we do.The gooseneck fittings are built this way for two reasons: # 1 is that assembly is so fast. Just plug the boom onto the mast and snap on the tack hook instead of fiddling around with fitting a gooseneck pin into the end of the boom. # 2 is that no hardware is bolted to the mast, which would weaken it. This gooseneck is strong and is very nice to the mast.
The gooseneck fittings are made of molded (vacuum bagged) carbon fiber in long blanks and then cut into strips on a table saw. All very easy until the corner and edge rounding, coating, and drilling, and of course mounting to the booms.All the hardware for sailing and all the running rigging is carried on the boom.
Sheet, vang, and outhaul all live on the boom.
The quick disconnect vang set-up is shown here.The dagger board trunk caps are machined for us from 3/16” G-10 plate. They are machined with a gasket notch and now are machined with a recess for the mahogany stiffener. The recess makes it easy to bond the stiffener in place and also makes the cap significantly lighter.
A good trunk cap is a luxury if you like dry pants and a necessity for towing, and is now included in the base kit.
We sand and chamfer the edges of the caps and riser blocks and we make the stiffeners.The daggerboard trunk cap kit uses many of the same parts that the hatch kit uses, except that the cap uses riser blocks to lift the turn dogs to the level of the cap and custom washers to lift them just a bit more. One of the two washers provides a tie point for the lanyard (see both photos below).The hatch kit will be included in the base kit in 2016 because everyone purchasing the PT 11 has opted for the hatch kit.
The hatch opening and turn dog fastener locations are now machined into the foredeck and we now pre-round the edges of the coaming opening and lid stiffener.The hatch is flush, which is necessary because it is sat on when rowing with two. It is also airtight (the gasket sits inside a machined gasket notch). How airtight? Removing the lid takes a good pull if the boat has cooled as the vacuum pulls the lid down tight.We machine a lot of small mahogany parts such as foot braces, back seat cleats, stiffeners, and oarlock riser blocks. We have gotten pretty good at producing parts that are basically ready to install and finish.Foot braces are almost as important as oars when it comes to rowing.
We have experimented with many different types of foot braces and keep coming back to these glued-on Sapele mahogany braces. They are easy to install (with the included template), lightweight, hard enough to hold a finish well, and made from a species that would hold up well even without finish.
The back seat cleats are also shown in photos above and below.
The photo below shows three of the finishing steps used on all the cleats, stiffeners, and foot braces.
The piece on the right has had its ends cut to length and angle on the table saw. The piece in the middle has had its sawn faces sanded and sharp corners rounded on a table sander. The finished piece has had its edges rounded with a sharp round over bit in a router table.
All the stock for these parts is run through a sharp thickness planer after cutting to make all four edges smooth before cutting the individual parts.
To say that we make a lot of these parts is not an exaggeration.
Shown are foot braces and back seat cleats for only five boats.
The oarlock riser blocks are not strictly necessary, but they give the sockets more support and give arguably better ergonomics, especially if you like to sit on a cushion when rowing.
A block of wood with holes drilled in it would work fine, but we machine them to the shape of the socket.
Making these parts is laborious and makes sense only if a lot of them are made at one time.
CNC machining them is possible, but would be expensive (5 axis machine) and the parts would still need finish sanding.
The drill press is used with a fence to drill both large and small holes on center.
The sockets are installed with the screw size that will be used for final installation and marked around as shown.
After cutting the strips into individual parts, the shapes are roughly machined very quickly on a large tilt-table sander. They are then finished on a smaller tilt-table sander with fine sandpaper as shown below.The back seat (also visible in photos above) is made from very tight grain Red Cedar which seems to be an ideal material for a removable seat. It’s very light, looks good, and doesn’t ding up the inside of the boat. We pick through piles of expensive wood to find the nicest pieces, plane them to thickness, and cut them with a template.The construction manual is what ties all the parts together.
The PT 11 manual has been the largest single effort of this boat. It seems to be paying off as we get very few “tech” calls or calls from builders in trouble.
The only embarrassing thing about the manual is that it is so thick (306 pages) and some find that intimidating.
The reason it’s so thick is that we try to show more with photos than with words and there are more than 700 photos in this book, showing every step of the building process.
The PT 11 is not a simple boat and while the manual needs to be carefully followed, total amateurs have built very nice 11’s and had a good time doing so.
The manual has undergone multiple re-writings (even very recently), which usually involves building a new boat to use as a photo prop for design changes or changes in process or sequence. The result of all this is that the boat is now both better and easier to build.
What do we do with our “spare time”? We make other stuff, such as turn dogs and carbon eye straps. We make these parts for our own boats, but we also make them for our friends at Chesapeake Light Craft, who have managed to sell many thousands of these parts for use on their own kits.
The turn dogs are machined from sheets of Delrin(TM) and we bevel the edges on the router table, which sounds dangerous, but really it’s just mind-numbing (and finger cramping). Small fingers like Ashlyn’s are pretty much a requirement for this job.
..each piece has the upper & lower edges chamfered on a router table...
The carbon eye straps are popular because they look cool, but also because they can be glued to a surface (such as a kayak deck) without fasteners. We make long blanks in a two-part mold (long enough to make 80 eye straps). After trimming and finishing the blank, the eye straps are cut, beveled, and finished by hand. Both the turn dogs and eye straps were just an idea (floated with crude samples) to our friend John Harris at CLC about 5 years ago. These parts now are a small industry and can be seen on boats far and wide (including our boats).What’s next for us?
Kit sales in 2015 challenged the production capacity of our shop so the thought of someone else taking over PT Watercraft has crossed our minds more than once. This would allow us to develop other boats and write about building techniques.
For the present, however, we are happy to keep producing the best kits we possibly can.
This is kind of a long post featuring my festival pictures, our booth, the Pt 11 on the water, a customer built PT Skiff, end show humor, & video links...
The Port Townsend Wooden Boat Festival is a great event any year. This year, the 39th, was no exception. We had two hot and sunny days and Sunday cooled considerably under cloudy skies. In spite of the Hood Canal Bridge closing earlier in the week and again for a flotilla, people made it to our peninsula.
I did not get as many festival photos as usual but here are a few. It is hard not to get the same pictures as everyone else. Everywhere you look seems photo-worthy.
For PT Watercraft, the festival is increasingly a family reunion of sorts. Among the thousands who visited, were quite a few builders of our kits; some of our earliest customers, some who recently completed beautiful boats, and some who are just beginning construction. We were so happy to see everyone. We even have show regulars who are still dreaming about building a PT 11 or a skiff, and they come every year to stroke the bright-work, listen to conversation, ask new questions. It is great to see familiar faces.
You can probably tell that I love our wooden boat festival even if I talk myself hoarse over the three days. I walked the docks Thursday afternoon as boats were filling the harbor, and again early Sunday morning. The Sunday Sail-by is a highlight, though this year I found myself talking to booth visitors more than watching the hundreds of boats out on the water at once. Still very impressive! I expect lots of videos will appear on Youtube.
Our annual helper, Cooper Parrish, raced the PT 11 in the 26ft & under, and then sailed around during the Sail-by. Cooper makes very cool things at Scaled Composites in Mojave and we are so grateful that he is happy to take time out and join us at the show. Our friend Simon Miles of 206 Composites here in Port Townsend, had the Patin out as well. The Patin is probably the first beach cat design ever. Interested cat sailors might want to check out videos of the Vela Patin.
Customer built PT Skiff 'Mojo', was in the water. It was great to have a skiff at the festival for folks to check out. Builder/owners Mark and Meg were rightfully proud of their boat. Mark chose to really spiff it out with various woods, a sprayed paint job in indigo blue, and some plush outfitting choices.
At the end of the festival, packing up has a party like feel to it. We all survived a fun but physically challenging weekend. Our friends and show neighbors, Chesapeake Lightcraft, often display a bit of end show humor. This year, they thought the Wee Nip bar next to them was closing the festival with 'BYOB' for a fill up. Well, John and crew brought a boat! Thanks John for all the laughs!
