You might also want to look at the Ericson Cruising 31. Good Old Boat has a review article in the Nov/Dec 09 issue. The owner is a writer for GOB, altho the owners did the review. I have that persons email if you want to get ahold of him about that model. At the back of that article, Ted Hood does a reivew of two other boats, a Seaborn and a Cal. All three he mentions would work offshore, He compares these three to 7 or so other 30' boats GOB has done reviews on, to show why these three get his nod over the others written about.
Then if you can not get around the ericson site, I'm thinking if olson34 is whom I think, he has moderated there many years, and knows the site like the back of his hand.
