I still think that we should design with the kids in mind, so a crew weight between 40 and 60kgs. If there is room for an easy boat for the adults, I think it should be wise to go up to 14 feet and design with the same idea cheap, light and simple.
For me it's those three things that makes the F12 interesting.
Btw. I'm starting to build the sshhh tomorow...
flathlander18, don't be a coward go ahead and build the DS12 it's a great boat and you don't risk a lot of money and we need boats out on the beaches
