Pre '83 models
You probably want to focus on models prior to the '83 model year for anything rough; I believe that was the last year they built the Cherubini design. Apocryphally, those built in the seventies are laid thicker and are even more sturdy, and I believe it was the Hunter workmanship of the mid-eighties that resulted in many of the negatives you hear about them these days so you might want to focus on the earlier boats even from that design.That said, for what you're talking about, I think I would look at something else entirely. The boat may be capable but the ride would not be fun.
