I'm with mitchell on this one. Quad or a twin/keel. Hell I weight 195 and have a thick 5'5" I can ride through mushy sections. I have a Hanson longboard and it is heavy and too long. Hell I even made a Grande Simmons and at 7'....still too big. For your weight I would not go over 5'9".....I don't like these models too fat (uncomfortable to sit on) or too long (feel sluggish) DawnpatrolSUP board above would be a no brains given your size. Don't be fooled into thinking it wont work because of the length.
