Here's a better way to get screws going from under the cockpit coaming to secure the Rapid Pulse back band that comes with kits. The manual (of the Wood Ducks) says to "drill holes on the underside of the coaming for the cable clamp screws. An awl might be sufficient to start the holes." Added to the difficulty of working from under the coaming is the fact that the holes need to be six inches apart, three inches on either side of the center line. Nope. It's much easier to drill those holes from above, before gluing the coaming ring on top of the coaming spacers. Not only can you get them precisely where you want them much more easily than from below, but you have an easy opportunity to drill-fill-drill. Drill the hoiles oversize, from above, then seal the underside with packaging sealing tape, then fill the oversize hole -- from above -- and drill the pilot hole through the hardened epoxy plug. Then, glue the coaming ring into place. When you are ready to screw in the cable clamps from underneath, the non-wooden pilot holes will be ready and waiting for you, already in their perfect places. You're welcome!
