But most non-slip solutions for boats are going to spoil the appearance

This idea is similar to
sprinkling sand onto wet paint or varnish except that you use a water
soluble 'grit' such as coarse sea salt, which when the varnish or paint
is dry is washed off to leave a stippled surface.

that is water soluble, however I wouldn’t use sugar or anything which
could make a sticky mess or attract insects.
So, when you've sanded off ready for that final coat you can if you
wish mask off the areas to be made non-slip.
Having glossy frames around the non-skid areas will look better than
just doing the whole area.
It will look even better is you can radius the corners.
Now, lay a thick coat of varnish within the masked areas making sure
you go right up to the edges of the tape.
Then before it dries sprinkle the coarse salt, as evenly as
possible over the wet varnish.
A sieve or kitchen sifter of some sort will help in getting an

and be safer.
