Vintage traditional boats often had raw wood decks that had a natural no slip effect even when wet. Nowadays, we put a non-skid texture on surfaces that could be dangerous when wet. It can be molded in the surface on fiberglass boats, or added to the paint on modern wooden boats. For the Chuck Paine pocket cruiser we have in the shop, we used a non-skid materials added to the paint. You mix it into prepared paint, let it sit 15 minutes or so, and apply it as you normally would any paint. In this case, I masked out a logical pattern on the deck with tape, rolled the paint on, and tipped it out with a foam brush to pop any bubbles and to even out the non-skid texture. It usually takes a couple coats to get a somewhat even look. You can’t really see much in this picture, but here’s the boat I’m referring to. The non-skid is in between the teak handrails on the cabin top/deck:
I also applied another coat of regular paint in the cockpit. While I was up on the mezzanine, I shot a picture of most of the shop. I have it pretty much filled to the brim with wooden boats ready for winter work.
Hope everybody has a safe and happy holiday!
