PDQ - you mention using soccer netting on life lines. We have little ones on board, and contrary to the racing types we want safety netting along our life lines to keep wee ones aboard.
I purchased knotted netting but to be honest it is pretty slim and I'm not sure it will last much more than one season. Do you use soccer netting in this manner and if so, how do you manage it, cut it, install it etc..
Sometimes as additional trampoline on a cat, but where I did not want to catch the air a regular tramp would catch. It was not comfortable (big holes), but would catch a fall.
Sometimes we attached it with cable ties. Lots of them, the black uv resistant type (VERY important - not the clear ones). Since they were placed at every square, there is a lot of strength. Other times I would lace a ~ 1/4" line in a spiral manner through each square and around the cable. That worked well too and was more durable. We only used the cable ties when we had made some change and did not feel like re-lacing the net.
Yeah, the net from West Marine is only good for a few seasons, after which you will be able to pull it apart with your hands. I know because in season 3 I lost my balance and put my hand through it.
The net they sell for batting cages looks even better - perhaps you can find that. It seems to last forever at the local park. It would be my first choice, but I came a across a new soccer net for free. Same material, different hole size, it seems.
