As previously mentioned, 2020-21 was largely spent reviewing our production process. Another redesign included the PT 11 foils kit. We took our ideas to Paul Bieker of Bieker Boats for his expertise with foil design. The new foils are thinner, using 18mm Birch plywood instead of 24mm Okoume. The Birch plywood is more dense, chosen for its strength at this thickness and not for it’s looks.\u00a0 The machined birch plywood is not as handsome for clear coating as the Okoume but we are quite pleased with the overall change.<\/p>\n

Modifying the foils kits affected many other parts of the kit, so those changes are are reflected in a total rewrite of the foils manual and changes in the boat itself (the daggerboard trunk is narrower, etc).<\/p>\n

Machining the daggerboard and rudder from high-grade plywood is a good way to produce very efficient\u00a0 and relatively light foils. The process is far from easy though. It has taken much trial and error and a very good CNC programmer (Turn Point Design<\/a>) to come up with the final product. The price of this foils kit reflects quite a lot of machine time for each set.<\/p>\n
