[Rhodes22-list] hull problems?

[Jim Connolly]

This has nothing to do with the cracking question, but I don't think Pettit Trinidad is recommended for trailer sailing.  You want a paint described as "multi season" most of which are ablative (soft) paint. Most hard paints lose antifouling ability when out of the water for an extended period.
