Port replacement
We have a 1986 H-31, and all six opening ports needed work, and the formerly transparent plastic no longer is. Boat US offers the original equipment replacement, but also offer a Beckson "Rain Drain" port that appeared to be the same size, and they were on sale for about $50 each. I ordered six, on account of the good price.Found that the major difference between the ports is that the Beckson ports have the drain located at different places. There was also a slight difference in the shape of the elliptical ends, but both problems were easy to deal with. I re-cut the ends and cut new channels with a round "Surf-form" tool, filled the old drain channels with epoxy paste. There had been some leakage around the old port, and the plywood core was delaminating. Again, epoxy to the rescue, this time a low-viscosity laminating resin injected into the affected area. The finished job doesn't leak, can be seen through, and looks decent. Took about 2 hours for the first one. The rest will have to wait for a no-wind day. Hey, I'm no ant!Howard s/v Valhalla
