A pleasure to help, nautilass. I'll add that the Net Systems website provides information on the proper repair of their knotless net material. The same techniques will serve to build the nets that you need as well. I'm of the strong opinion that sailors are better served building what they can if they can as they will then be able to repair it when (not if) needed. Building the nets is simple though repetitious. Think meditative. Netting needles are available from some craft stores. A Google
search will turn up something as I cannot recall
the name of my source. The only trick part of the whole project
was the pieces that cap the battens at the corners and provide the means to attach one batten to the next. I used 1 inch delrin rod (avail. from McMaster Carr) cut into oh, 5 inch lengths. Use a drill press and buy a 1 inch and a 3/4 inch bit. Spade bits will do fine and are inexpensive as well. You don't want a bit that will self-feed. Clamp a block of wood
of some thickness, say 4 or 5 inches under the bit and drill a 1 inch hole into it. Leave the wood
block in position with its perfectly centered 1 inch hole in it and replace the bit with the 3/4 inch one. Pop one of the lengths of delrin rod into the hole in the wood and drill the 3/4 inch hole in its center to a depth
of say 3 inches. Do this for all the pieces necessary, 2 per corner plus a couple as you will surely make sacrifice to the sea gods as you do the install. Take the drilled pieces and, in the not-drilled end, drill a hole for the connecting bolt. Then cut or grind opposite sides of the piece perpendicular to the bolt hole in order to leave maybe half the thickness as an ear in the middle of the delrin rod. So, 1 inch rod with 1/4 removed from each side to leave 1/2 in the middle. Slip 'em on the ends of the battens an bolt it all together. I used 5200 on mine but it was a waste as apparently delrin is impervious to it and so, no adhesion. Don't bother as there is another way to solve the problem of the ends slipping off the battens as the nets flex.
The only other bit you might find useful is that I used electrician's shrink-fit tubing to cover the length of batten to protect them from UV. It's worked great. Don't use the type with adhesive
as repair is problematic. Even comes in colors though not very lightfast. I used black.
Wow, that was windy!
