Does the temperature have any effect on fiber-glass (below 32F)? For example: if I was going to store it out-door but covered for the winter time? (Chicago)

In “Help with Nacra 5.2” Jake mention hull fitting cradles. I don’t have those on my trailer? My NACRA 6.0 (hopefully) will be stored in-door, so should I buy those and install on my trailer? I think than someone mention in earlier posting that storing your catamaran on trailer rollers might cause deformation of hulls.

I found those cradles in Murrays.com catalogue on page 58. Are there any other suppliers where I can find those hull cradles?

Thanx
