I have chartered the 440 and/or the 450 probably 6 or 7 times in the Carib and I currently own a 42 in the New York area. For a couple who uses the boat as their primary whether as live abroad, day sails or coastal cruising, I think the 42 is one of the best fits size, handling, performance (we use the Code 0 almost all the time) that one can make; however, for charter for 4 or more my favorite boat by far (and I have chartered FPs, Lepoards, Catana etc) the Lagoon 450 is the best. Hands down the flybridge is the determining factor every time. If money isnt the issue, book the 450 and dont even think about it.
