I believe the Canadians put Kevlar on their yellow H18 when they sailed/dragged across the Northwest Passage in 1988.
That was for impact/penetration resistance (which Kevlar is very good for), not abrasion resistance.
From page 13 of the paperback edition of
Polar Passage:
"I named her
Perception, and before she left the factory the bottoms of her bright yellow hulls had been reinforced with thin strips of bullet-proof Kevlar plastic, which I hoped would make her impervious to holing by ice when sailing. To protect her and ease her way when she was being hauled over the rough ice, we'd made a set of thin plastic runners, which strapped onto the banana-shaped hulls like a hockey player's shin pads."
Scary how fast I found that. My basement's more organized than I thought.
Anyway, the most cost effective, abrasion-resistant material that won't fuzz up when it's exposed by abrasion is . . . s-glass.
