G'day,
No problem at all. I have built a few flat bottomed proas, all worked
well. Main decision is whether to put any rocker in. I wouldn't, as
the boat then tends to sail on the front part, so you are more nose
down than otherwise. I guess if you got enough weight aft, it might
sail on the back part, might even plane, but if it is skinny enoufgh,
this is not necessary. Let me know the dimensions, sail area,
materials and payload and we will see what we can come up with.
Gardner,
You don't need to fillet stringers unless you are glassing over them.
Fillets which are glassed over only need to be 10mm/3/8" dia and made
with Q cell, not glue powder.
I am always busy, but never so busy that I can't find time for proas.
Anything you want, let me know. I think a proa will be easier to
infuse than a dinghy. Or at least easier to make the shapes once you
have made the panels. And big panels are much the same to infuse as
small ones, just more expensive if you stuff up.
regards,
Rob
