Starboard
I replaced my old, warped teak plywood companionway boards with a two-piece hinged section made of starboard. I cut into the upper section an operable 8" x 10" portlight with a bug screen that gives light and ventilation.I made the entire rig out of "Starboard" available in sheets at any marine supply store. It's a polymer that most common plastic cutting boards are made of. It's pricey, and there are alternate poly - type materials out there in sheet goods available at your local home improvement center. Azek is one for example. The new "starboard" companionway was made with a 1/2" thick material. A 4' x 8' sheet runs arond $80 at a marine store. It's easy to cut with any circular saw and sands OK. No splinters! The best is that it needs no paint! The downside is that it is heavier to handle than the three smaller plywood boards due to the portlight as well as teh added piano hinge. The starboard product is weather-proof, won't rot and is very strong.Fair winds,,,,,,,,Stu
