After pulling up the flooring, bunks etc. I found bad rot under the streetside rear bunk (under the water tank). The surfside's belly is fully glassed and gelcoated, and on the inside the plywood floor is fibreglassed over around the edges.
Has anybody replaced the plywood on these Surfsides? Is the wood just glassed in at the edges or is the wood all resined in ?
It looks like the water tank was sweating and dripping on the floor for some time . I'm not sure what i would do if it was me but i'll tell you what i have done with my boler
. I had a 9 " hole in the floor so i cut it square and made a patch ,the i used a piece 1/8 " steel and screwed it to the underside , make sure the steel is large enough to distribute the weight
. I then glued in plywood and fiberglassed it over . Then i layed down a sheet vinyl . This has proven very effective .
