I get what you're saying about cost. As the last time I looked up Spectra netting, it was going for about $10/sqft.
As far as alternatives, I've only thought it through, having long since sold my Searunner
. But I'd avoid anything made of polyproplyne, the same material which is in waterskier's tow rope
. As it gets along with UV about as well as Vampires.
On coatings, I'd figure that something like Maxi-Jacket, Maxi-Jacket II, or RP 25 would likely be safe to paint
onto things. But I'd call their respective maker's first.
Not that any of said mentioned coatings are exactly cheap
I know that some guys just paint
their netting, but what always set me on edge about that, was the possibility of the solvents in the coatings damaging the netting @ the molecular level. AKA chemically weakening the net's fibers.
What about some stitched, webbing netting? Like, say, from someplace which teaches gymnastics, or a parachuting school
, etc. And has to replace it pretty frequently for insurance
Then, once you got it, you could always run the thing through a sewing machine
, using UV resistant thread. As well as"painting" it with the best coating that you can come up with.
Might a call/email to Jim Brown, John Marples, or Richard Woods be in order? That, & or a multihull
