Gates are for cargo loading, hop over it.
There's only one way sailors attached netting--that's with lashing. Th eonly thing I could come up with on the web is:
Tying a Parcel
showing what they call a "parcel knot" composed of two other knots. But if you watch the animation slowly--you can see how this knot can be tied, and then the free end of the
line extended another few inches down a rail, etc., and another knot made, continuing on down a rail.
I can't remember what the proper name of the marine version is, but it also makes a damn handy way to secure the mainsail to the boom when a squall is about to hit. You basically knot, move down two feet, knot again, and there's very little fuss or passing through at each "knot".
Anybody with a better memory know the proper name for what I'm thinking of here?? All my knot-sense is in my hands, they don't ask my head to get involved in it.
