The sit on top I used had a self bailing hole just aft of the foot braces that made the onboard water problem managable. Not sure you would need this if you had a good hull design... seems like too much drag to me. Probably a better way to manage it like draining it over the sides?

It seems like S&G is the way to go on this. ANyone want to design a boat for me to build?

These things are fun to paddle. I just need one that tracks well too.
