Long ago, before rotomolded kayaks, whitewater kayaks of the day were being torn up from abraision against the river rocks. Abraision comparison tests were done between fiberglass, Kevlar and polyester fabrics.? The clear winner was polyester fabric. Two common examples are Xynole polyester and Dynel. Both of these products surpass kevlar for abraison. Kevlar is better for impact loads but not abraison. Polyester fabrics are much less expensive too.

Bernd: I was wondering if the 520 could use a standard sloop setup like the Eco 6. I realize the mast placement would be different. I would rig it like the Eco 6. Mighty expensive needing two roller furlers. Otherwise the boat is great. If I wanted greater abrasion resistance would I use Kevlar on the bottom (Sand and shells abundant).
