many questions about repairing/replacing stringers

[dan4836]

I am doing the same project now.

I cut out my deck, removed the fuel tank and foam. Cut the tops of the stringers and bulkheads and was planning on using Seacast or Arjay to fill the void.

What I decided to do is pick up three sheets of 3/4" A/C plywood. Cost all the wood with polyester resin. Install the 3/4" stringers back into the stringer cavity.

What I found - the stringers were made with a piece of lumber (not plywood) the bulkheads are made with plywood and are much more difficult to get the wood out.

I will be glassing over using 1708 and chop strand with at least four layers.

I was able to consult with a boat builder and he said the plywood material I am putting in is just to fill the void. The 1708 and chopped strand will be the new structural stringer.

After this is complete, I will drop my 3/4" plywood floor. I thought about using a composite but by the time I have to re-do the floor it should be many years....

My floor will be laminated with two coats of chopped strand.

I will post photos soon...
