[Public-list] Another Kingsland Crazy Idea

Good day Roger - 

Your ideas are not weird at all... I have been thinking about the same
thing.  In the wooden boat world there is an very old tradition of pouring
melted pitch or hot tar into inaccessible spaces to prevent water or crud
from collecting there.  I had a space like that in my old boat's stern.  In
our Alberg I would like someday to make plywood triangles that can be
screwed in to block off those spaces.  Periodically the triangles could be
removed to allow cleaning underneath.

I don't much like the idea of pouring epoxy down there because our hulls -
though strong and thick - are quite flexible and two bad things would be
likely.  One is that the block of stuff that fills in the space will
inevitably separate from the hull and water and crud will get under it.  The
second bad thing stems from the fact that the block of filler would be much
stiffer than the hull - while it remains stuck to the hull there will be a
hard spot around it's outline that the hull would have to bend around - and
this can cause a failure in the adjacent hull laminations.
