336 is 50% larger
LOA is not a great way to evaluate the "size feel" of a boat. Check out displacement and sail area for a better idea.For example, a h380 is only 4.5 feet longer than my h336, but it is a much, much larger boat.That said, I think that the major disadvantage of this model is the mainsheet rigging. If the boat you are considering has the mainsheet led to the steering pedestal, you can trim the main just by pulling on the sheet bare-handed. However the traveller is so small it is useless except to pull the boom that last foot to centerline. And forget about any kind of useful bimini, the mainsheet tackle will be in the way.If you have the "other" rig, with the traveller forward of the companionway, then you have to trim the main with a winch. That's fine if you have the extra winches (seems you do) but it's harder to singlehand.If your boat has the wing keel, it will not be very weatherly. The compass will tell you that you're tacking through 90 degrees, but the GPS tells a different story. Lots of leeway.But the main advantage is living space! It's a little floating condo. I've chartered 38-foot Beneteaus that didn't have as much space below.Good luck with your decision.Paulsv Escape Artisth336
