Having a bailer in a dinghy is a very important thing. Dinghy sailing in gusty wind can get wet, especially if the captain is not paying attention and dips the rail. Russell came up with a handy bailer idea. 
This oblong fabric softener bottle offers both a wide mouth scoop and a low profile that fits neatly below the seat tongue. Stashed inside for minor spray is a sponge. This green sponge was a waste of pennies. It does little more than spread spray water. A good absorbent sponge like this PVA sponge or 3M C41 7456-T is a much better choice. I personally like these pop-up sponges but they do not hold up well if left outside, which is kind of the point environmentally.. 😉 
This bailer installation does not interfere with nesting. There is room to spare. We used carbon glue on eyestraps and a bungee cord to keep the bailer stored out of the way but within quick reach.
If you capsize, sweeping the water out with your arm or sloshing out the water before getting back in gets most water out. See it all on this video. PTW
