The front stringer caps were worn away, exposing the top of the wood. This could be from them never being properly attached to the deck in a previous repair. The hull flexing would move the deck from side to side, gradually grinding the fiberglass away. The fuel tank has a few pinhole leaks on the top and the hose is brittle. The tank is going to a shop for repairs and the hose must be replaced. Fuel fumes under the deck is VERY BAD. Check for some photos on the net and see what fire will do to fiberglass.
