Nick is right about hobies being fun boats for teenagers. He is also right that the Getaway (which is almost identical to a Wave but bigger) is good for a family boat. However, righting a Wave is far easier than a Getaway and a Wave can be pushed up on a beach by one person - not so a Getaway. I was torn between the two and ended up going with the Wave so that the kids would be able to sail it alone without me having to go help with anything - But then I also have other boats for the family to cruise on.
PS - the best thing about either the getaway or the wave is that they are made of rotomolded plastic and not fiberglass. You can run them into the dock and they wont care. You can drag them over gravel and they dont care. Fiberglass demands a lot more attention.
