You should rely try it before you buy it, if you can. I bought one in 2007, the model with all the fittings and stuff included. This is my review.
I am 178 cm 70 kg, and this boat was not comfortable for me. None of my friends could get in it

The sticky back band is a cool idea, but it was to give rely good support. In the end it just more or less stuck to my but. The plastic things that hold your thighs are always in the way when you get into and out of the boat, they put my legs to sleep so in the end I took them out and put normal fittings. The snowboarding things for the back are not so well located either. And the food pegs do not give solid support.
Paddling wise. The edges of this boat will not go unnoticed, but if you are careful while paddling it's not a problem. I was either paddling this boat or a creeker and had to get used to the edges all the time. Not too bad, just made me remember to stay in a strong paddling position. For me the boat was a bit hard to roll. I think this was because of my lousy technique and the boats more or less square shape and high side walls. My friends, who managed to squeese in, also had a hard time rolling it.
Because of the boats funny shape it does not stack well with other boats. So it was always a pain to put it on a roof rack on a car. Sure it looks good to hold it on the side when you are biking to the beach but if you are serious about moving around with it get extra straps.
...but if you get the chance to surf this boat on a wave you will forget the sleeping legs, back band pushing your butt, and all that and just surf. Compare to a Dagger kingpin or other bouncing boats this one surfs so smoothly. It's amazing how it just glides on the waves.
In the end I sold mine and was happy I still had my old trusty Kingpin
Conclution:
try it
surf it
make your own fittings
as a general play run river runner, probably not the best boat you get
