IMO, that boat is too small for a man your size. I suspect your weight is going to put it so low in the water that it will be a slug to paddle.
Case in point,I bought a 14' Necky Vector SOT that is rated to handle my 230 lbs and it does as long as I don't mind sitting in a puddle. That wasn't an issue in the summer, but in 40 deg water it isn't cool.
I think you would be much happier with a WS Tarpon 160 or a Native Watercraft.
