On a Horstman, you will find the deck-to-hull connection to be supported by a "sheer stringer". You can drill vertical holes through this stringer to attach wooden mounts for the bow nets. On my
Searunner, with similar construction in this area, it has proven to be lightweight, durable, strong and inexpensive. Start with a vertical grain fir timber 3/4" thick by 2 1/2 inches wide. Mark a center line down the middle of the
lumber strip, on its wide side, the mark centers every three or four inches. Drill one inch holes on these centers, the rip the timber down the middle to create two long "bridged" supports. Then, on the "closed" side of the thin width, drill 3/8 inch holes vertically where the holes for the supporting "tree nails" will go. You can start by temporarily tapping 3/8 inch birch dowel pins into the first hole and the first hole in the
deck. Then, sequentially drill and insert each succeeding pin, bending the timber as needed, to establish a fair curve. Then pull all the temporary "tree nails" out, shape all places that will benefit from a radius, using a router bit. then
epoxy the strips well and prepare to permanently glue them in. Then, dip the dowels into
epoxy, taking care to mask inside so as not to drip epoxy down the inside of the hulls. When hardened, saw off any protruding dowel, sand them to match the radiused top of the bow net rail, epoxy, prime and
paint. I use the small Spectra cord available in rig shops to attach the nets to the rail. I'll try to send some pics later (Im using another computer at the moment).
And, like FSMike, I REALLY love my Sunrise nets.
