Contrary to the previous message....
the hulls are fairly different.As the post suggests, the capri is more of the racing boat, the Cat a cruising boat. There are better accomodations below in the Cat (for cooking, sleeping, etc) while the capri is the more spaceous of the two above decks -- cockpit is larger, and the hull is appreciably wider with walkways along topsides -- these allow crew more freedom in movement, access to sails, etc.Depending on what you really want the boat for, one would be preferable over the other, but you can't really go wrong owning either boat.Good Sailing,Brad
