C310 is an excellent choice
We took delivery of our C310 the first of April and have been sailing almost every weekend since. The boat handles very well and is very easy for two to sail in most conditions. We have the furling main sail and wouldn't trade it for anything, there is nothing quite like being able to winch the sail in and out of the mast from the cockpit. There is plenty of head room (unless you are over 6') and the large forward berth with the innerspring mattress really sold us on the boat.We sail on the Columbia river in Portland Oregon and have found that the 310 holds its own against most of the other boats on the river. And the quality of the Catalina is excellent, very few problems with this boat.Wish you the best with your decision. Good sailing. Hope to see you on the list of new C310 owners.
