Spreader patches....

[UNCIVILIZED]

Personally, I'd skip rollers on Dyneema shrouds. But that's just a gut instinct. Primarily because I wouldn't want so much repeated, point loaded friction on them. With or without a cover on the Dyneema.

Though going to something like "rollers" shaped like tennis balls, & made of UHMWPE might be a decent option, perhaps???
Machine them to shape, drill for the shroud, band saw in half, & bolt in place overtop of some chafe sleeve. This in conjunction with Maxi Jacket or RP25.
That way you'd likely reduce the point loading by a decent amount. Knock on wood.

Time to call Colligo Marine, for some expert advice

Is chafe really that big of an issue with the sail? Especially with patches installed on it, possibly in conjunction with UHMWPE strips on the spreader tips.

Thanks for the comments everyone. I'm going to be very careful in the near term. and am still considering the patches/rollers. I'll keep you all posted.

Here is what I am dealing with up there. I have since shortened the upper spreaders by 3" to try and reduce the impact when sheeted in tight. It is a blade jib, but the leech still hits all that hardware up there when tacking.
