Hey guys and gals,
Hope all are well. Ok....so much to my dismay,my boat cover had a hole in it, resulting in water getting into my boat and unknown to me,in froze over the winter......it cracked my hull in a small(1") place on the strake. I pulled up the rotting floor in one corner and the foam is completely waterlogged.
What to do....I believe this to be a BIG undertaking,i have no garage to work from so no splitting the hull to access the hill for foam replacement. I thought about just covering the old floor with plywood and going fishing.....
Thoughts people?
Thanks and GOD bless
