If you just want the hull speed back what about waxes like they use on skis
and according to the old surfer movies (I have no knowledge about surfing)
on surfboards.

Don't waste your time. There's little you can do to resurface a plastic
boat. They scratch so easily that any effort you put into smoothing the
surface is largely a waste of time. Sanding and compounding doesn't work
because the material is too soft. I suggest that you just paddle them
and forget about it.

If you're determined to do something with the surface, larger "hairies"
can be removed with a razor blade and smaller ones can be flattened with
a heat gun or by passing a propane torch over them (use a flame
spreader). If you go this route, be careful, as the hull material melts
at a low temperature. Deep gouges can be fixed by plastic welding.
Harbor Freight sells a plastic welding kit for $20 or so that should do
the job, if you feel you need it.
