I havent sailed the 10M (lots of other Pearsons, just not that one).
The 37
Cutter is a great design, but there are some fit & finish aspects which are less than ideal (presumably due to being built by Hunter). One of the most annoying is those damn plastic portholes...a bunch if them.
I used to own a 37
Cutter deep
draft (I hear many negative comments on the shoal
draft version). Loved it. Excellent sailing characteristics: decent in light air, well behaved in heavy stuff (sailed mine in up to
hurricane force conditions), very well balanced (I could balance mine, set the
wheel brake, and walk away from the
helm for at least a few minutes in calm sea state...she would track like a freight train). I cruised my extensively, no transoceanic crossings, but plenty of multi-day runs in GOM and N Carib. I know directly of several that have done transoceanic runs and I would not hesistate to take a well outfitted one across.
There are several threads here that discuss the 37 Cutter, give those a look. Also a very active owners group on the
Internet with lots of posted info. I do not have the URL handy, but a search should turn it up.
