You may find that replacing the ply is cheaper. I just bought new timber
for the storm boards on my boat. The Ply was cheaper than the paint. By the
time you buy filler and/or glass and do the job it may be in your interest
to just buy a fresh sheet of ply.


Have to agree. Plywood has come down in price in this area. This
summer, while doing a renovation project, I was pleasantly surprised to
find that outdoor G1S spruce plywood was only a couple of dollars more
expensive than that crappy 'chip board'.
(of course, this was before the hurricanes)

Would I need to use a special kind of plywood - some "marine" grade or
something? I think that the existing floor is coated with Cetol which
is why I thought that would be the best finish to put on.

Use an industrial grade ( same glues without the price of marine ply).

A/C grade would be fine.
Side one is an A grade smooth good quality finish.
Side two is a C grade, rougher with knots.

If you don't want to cut it yourself the local kitchen makers will often do
it much cheaper than a shipwright.

I've read that the glue in outdoor plywood is the same as used in the
marine version. The major difference is that all the 'knot hole' voids
are filled in the marine grade but not so in outdoor grade.
Since your dingy is old and will probably be replaced within 3-5 years,
I'd go with the cheaper plywood and seal it well with a good oil
primer/paint. (or Cetol if you already have some)

How about a sheet of plastic? I was looking at the plastic lattice but it is
a little flimsy. Thick lexan is strong but expensive. Any ideas?

Nice idea but lexan is slippery and as you said quite expensive. Most
plastics are.

Nonskid tape on the lexan. I also saw some hollow stockade fence that might
work. I would like to get rid of the 50 plus pounds my waterlogged floor has
become.

p.s.: found 12 inch wide duct tape at HD. called "Big Fix duct tape" goes in
my crsh bag.

It's not the same glue. Additionally, marine ply doesn't mix woods
(which expand and contract at different rates, breaking bonds quickly)
and the plies are thinner - more plies & greater strength.

Though I love Cetol, the floorboards can be taken home to refinish
properly and varnish is better for this application as it stands up to
abrasion better.
