Todd:
I saw a picture of 22 foot sailboat whose weight was over 2800 on
a trailer using 6 rollers instead of bunks. It was a fiber glass hull.
The boat was 8 foot wide. But the boat was in Australia. I noticed it
because someone was asking about whether you could use a roller system
trailer for a Rhodes 22. That boat matched us well against the R22, so
I guess you can.
