Kakkerlak said...Looking at covering a few bases at once: downwind, crusing, sup-fishing. What would be the minimum length to be able to succesfully downwind (not talking about racing) does width make a diffrence? Will apprecaite some advice and even the some abuse which is expected

Call Dale Chapman, he will make it as wide as you need it. Even custom install some fishing rod holders into the deck.

Go a DC14 at 30 wide and have a super fast board that would be great for everything you need. Mine even surfs great.
Would be great for trolling, just paddle along with rod stuck in the rod or rods in the rod holders with the lures out the back.
