Spray rails on 1960 Shell Lake

This Summer I decided I needed to try adding some sort of spray rail to my little fiberglass fishing boat in order to stay dryer while motoring in the wind and chop. I wanted to experiment with changing the shape of the stern some also as this boat has a round chine which is not good for planing or cornering while planed. Maybe it will give me some more top end?<br /><br />I hade some 3/4" x 8" recycled Redwood boards (siding) that I wanted to use for this project. When I got the boat a few years back I refinished the Redwood gunwales and built a new deck out of Redwood and Fir, I wanted the rails to match.<br /><br />I had to join two boards at an angle in order to get enough material to go from stern to around 20" from bow. I made a doweled joint glued with epoxy and microfibers. (West System) I did the scribing with a saber saw and a belt sander in the lawn.<br /><br />

<br /><br />I needed to grind clean the stepped in profile of the hull so I had something to glue the rails to. Used an angle grinder. Once the dirty work was done I set the boat on the trailer upside down and wheeled it into the garage. I then attached the rails using more epoxy and filler. I mixed it as thick as I could get it while still wetting out the filler. Before I added the filler though I brushed some of the unthickened epoxy onto the Redwood and the fiberglass at the joint.<br /><br />

<br /><br />Once the joints cured I scribed the outer edge of the rails. I made a tool out of a scrap of wood with a hole for a pencil. I cut the outer edge to shape using again the saber saw and belt sander. After getting the shape of the edge just so I coated the boath rails with unthickened epoxy. I squeegeed it in. At this step I mixed more epoxy than the wood would absorb in a short period and it was hot out so I put my mixed epoxy and cup in the freezer while the wood soaked. An hour later I pulled the cup out of the freezer and found the epoxy to be solid, cured I thought, I set it on the workbench. A bit later I picked up the cup to toss in the trash and the epoxy was flowing again! So I spread it out on the rails and proceeded with more coats. I kept this cup alive the rest of the afternoon this way!<br /><br />

<br /> <br />After all epoxy had cured I varnished the rails and sanded and painted the bottom of the boat because it needed it. Not too shabby for an old boat!<br /><br />

Re: Spray rails on 1960 Shell Lake

I had reached the bottom of my resin and hardner containers and the pumps wouldn't pump any longer so I dumped the rest into the cup and mixed it. It was way too much and wasn't soaking into the wood fast enough. I put it into the freezer before it began to warm and cure. I doubt it could be stopped once that process begins.<br /><br />BTW the boat does run dryer. I'm not sure if any change to my blistering 13.5 mph top speed, I havn't checked it yet and I put in that trolling motor and battery before checking. But there was a big difference in turning while planed. I used to be able to roll the boat over till the gunwales got wet in a turn, I probably could flip it if I wanted, now it stays a lot flatter. I can still roll it up if I crank the motor sideways but it takes a lot more to do it now than before.
