I have an old inland surfer 4-skim. it's a REALLY small board at 4.4. I'm 215 and can ride it for days and my sis' ex at 250 can ride it as well. it's not the "ideal" size for me but scored it for 100bux back in 2008 and we still take it out almost every time for some fun. it's a board that with a wave lacking push it'll still ride wireless due to it's size.
those boards above should support you all day long. broadcast is one of the best "boat boards" out there and lots of beginners have started on it. we had the 5.0 back in 07-12 and used it for years with all kinds of weights..
