Do as you choose, but IMHO, carpet belongs in houses, not on boats.

Can't think of a single reason to put carpet on a boat, but everybody
has gotta be someplace.

Stitch and glue driftboats are a special case, that make
a good general point, I think.

A driftboat (a dory that drifts down a river) gets its
bottom pounded like no other boat. No matter how
much glass you put over the bottom and chine, cuts
in the glass skin will inevitably expose the plywood.
Then the plywood wicks up moisture, which gets trapped
almost forever, between the glass skins.

Some guys (montana boat builders dot com) have essentially
solved that problem (for stitch and glue boats anyway) by
puting hot spray truck bed liner on the outside.

Another way to deal with it is to use plastic honeycomb core
for the bottom panel, instead of plywood. If you do that, you
need a little extra glass, to stiffen the panel sufficiently.
But when and if the skin gets cut, the moisture does not
wick sideways into the honeycomb.

For me it's all about do-it-yourself boatbuilding, not
necessarily with wood. Plywood makes good side panels
on dories.......a place that doesn't get pounded.
For bottom panels on driftboats, I don't like plywood.

Plascore (or nida core) might be a better core for
any homemade boat.

Which reminds me - a Lake patrol man showed me the bottom of his
airboat one day. To allow it to dock right up the ramp onto the hard,
they fitted the bottom with a low friction plate - either high density
polyethylene - or it might even have been teflon.

Don't use sand (silica). It will be coming loose continuously and ruining
all sorts of mechanical things and surfaces due to its hardness.

Use pumice grit. Provides a tread, but doesn't spoil mechanisms if it gets
into a machine.
