A number of years ago I did the sole of my H33. The original rotting mouldy teak and holly ply was fastened with screws (teak plugs) and silicone. I removed the wood, scraped off the silicone, sanded the bare gelcoat and put a non-skid rubberized paint on it. I left the sump covering original. Looked good and was totally functional. With all the wood we have in the interiors we really don't need more wood on the sole. With my current 37C, I will refinish the original t&h sole but when it wears out or gets totally grungy, I will remove it and paint. I will pick a colour which will highlight the rest of the interior. Wood soles are not necessary, are expensive and add nothing to the boat's structure.
That said, there are some great products available as alternatives to t&s ply. The look just about as good and are far less maintenance, nothing sticks to them or stains them (not even epoxy resin), they are good nonskid and dent/scratch impervious. But be willing to spend the bucks. I would rather put the money into something useful like electronics, sails, solar or bunk cushions.
