Re: Jerry can & fender covers material?
UV is nasty, it is hard on everything.
Lashing a 2X4 to the stanchions and then lashing jerry cans to the 2x4 and toe rail does work; I do that when bringing Turicum (40 gallon tank) back from Maui (5 a side). Tying to lifelines is a very bad plan. I do not cover the jerry cans, but I think they would be more secure it they are covered AFTER being lashed. BTW - we cut up a cheap garden hose for anti-chafe.
Fender covers do help in keeping grime off the hull, but they should not be tied to lifelines. Go around the base of the stanchion.
