Here’s one I managed to miss last year when I was looking for a car-topable non-kayak that would be easier to launch and manage single handed than my Norseboat and to explore some areas that do not have ramps. Kailua Kanu in Kailua, Hawaii, makes a nice sixteen footer that weighs only 80 lbs and costs only $3800. It even has an available sail kit!
The pictures are caps from the flash movie on the site’s homepage, which otherwise go by too fast to see. Looks like a good choice if you don’t have the time to build an Ulua!
