: Nylon does absorb moisture (it is 'hygroscopic') but I doubt it
: would be a problem in this application. Nylon 6 can absorb up to
: around 9%, but nylon 6/6 absorbs much less. Typically, nylon has
: excellent abrasion resistance (it is used for bearings), better
: compressive strength & any moisture absorbtion will cause it
: to swell, tightening any screws used to fix it.

: Nylon has a higher softening temperature than HDPE which'll mean
: it's not as easy to heat-form, and in un-modified grades it
: suffers more (though not by much) than HDPE from UV degradation.

I really prefer UHMW for that application, though it's considerably more expensive it wears much better actually should last the life of the boat, normally the steel fasteners will wear thru before the UHMW wears.

Btw, UHMW = Ultra High Molecular Weight (poly)
