cockpit floor busted
 

My daysail boat open cockpit (Tempest22) floor is making cracking noise when
I walk on it.
There is small crack also.I patched the crack with fiberglass cloth.
Now I have to solve the problem to prevent farther cracks.
I 'm considering 2 options:
Cover the floor with playwood and fiberglass over- details like non
skid and glue between playwood and current flooring arise . Someone
recommended applying expendable foam to seal the playwood to floor

Second option is to re fiberglass with cloth and several layers , and fill
the space between hull and floor with expendable foam to support the weight
of the crew.
I lean toward 2 option.
please share your suggestions

Thank you.
