re: Need input in designing duck boat..

we built a mold and laid up six 14' flats with it
couple of things

1) unless you are an engineer there will be some trial and error
2) we had to add on a cavitation plate under the transom because they wanted to hop up and down
3) know your outboard weight and design to that
4) flat bottom is what you want for duck hunting but it will beat you to death in a chop
5) higher gunwales are better
