Okay, based upon your posts, since you don't care about speed, I would recommend a Hobie Wave. Simple, very durable boat that you can have a lot of fun with. It can carry a lot of people, or you can sail it by yourself in heavy air and have a blast. It comes with just the mainsail, but you can always add a jib and or a Hooter later to spice it up if you want.

Problem is that used ones are hard to find -- and when they become available, they are immediately snapped up by the people in the Wave fleets, because there is a great demand for them.
