make one out of 3/8" plywood
. Can divide it in thirds athwartships, make "hinges" out of webbing, so can store it beneath double berth when not in use.
Inflatable floors are extremely vulnerable to fuel
spills, and sometimes their quilting fails leading to huge hernias.
The wood "floor", sealed with epoxy
, then primed, then painted and with non-skid will work
fine for a long time. Might have to replace the hinges when they sun-rot. Ours, we used wee short counter sunk screws to attach the hinges to the timber.
Also, "starboard" might work
. I have never used it myself, though.
I suppose you might find another inflatable floor for some other brand of same-size dinghy
, but so many small differences between dinghies, don't know if that approach will work.
Another benefit to changing to plywood
will be more depth
inside the dinghy
