I can't help you on the name of the hull but someone around here should be able to help with that.
What I can tell you is that even though Sleekcraft is a good brand with quality hulls, I would keep looking unless this one is availible for a lot less than the current asking price. There are a lot of boats out there that have a better engine/jet combo and complete interior for around the same money. You might have to travel a little for it but you will be better off in the long run.
Good luck.
