thanks for the tip
perhaps you can give me a simple solution for this
next project.
I have found several different sources of closed
cell foam, some pour in and some cut to measure blocks and boards, that I plan
to use to achieve positive flotation, Some foam is labeled 1.7 and some 2.2 lbs
per cu ft. The heavier types of closed cell I do not plan on using.
Compared to a cubic ft of air, what is the best way
to find the positive floatation mark on the boat to keep the height of the
cockpit seat level with the outside water level but no deeper. For
example: suppose the worst case scenario and the boat is completely filled
with water (saltwater that is) I want the water to drain out to the level to or
less than the cock pit seats.
