> Toto as designed has 180 lb floatation.This is the volume of the flotation chamber in cubic feet times the
weight of water in a cubic foot. 180 lbs floatation would float the
weight of the boat if swamped. Subtract the weight of the boat from
180 and you might get 120 lbs. The normal life jacket has 22 lbs of
bouyancy. So, the floation in the boat might keep the boat plus 5
adults in the water alongside of it afloat, all of them wet and miserable.
My Piccup Pram has about 760 lbs of floatation, so if it were upside
down I could put 3 adults on the bottom and we would all be completely
dry...that is if we could get out of the boat and onto the bottom
without getting wet.
This is different than the displacement which is the weight of the
water that the boat displaces. If you take the normal displacement
given on a set of plans and subtract the boat weight you have the
weight of allowable crew and supplies. e.g. My Piccup displaces 490
lbs. Subtracting 100 lbs boat weight gives 390 pounds of crew and
supplies. Or 2+ adults. I've had 4 adults in it and it is slow, but
sails fine that way.
Jim gives his expected displacement on his plans at the waterline at
Whew. That's a lot of words when you already have your question
answered. Sorry. I just got started and couldn't stop writing.
