newb-stability-outrigger?

[sdcityboy]

I'm 5' 8" and 235 lb(and a replaced hip) and i decided that for some fun and exercise i would try kayaking. got a great deal on a used cobra explorer. took it to the bay and practiced self rescue and paddled my butt off. so why not add fishing! Now i'm hooked. Need to upgrade. After maneuvering my fat ass all over this small yak (11'3"x31") stability is my main concern-can't see hitting la jolla without the full use of the old hip. Was thinking about the fnd but now i see this web site with sort of an outrigger. looks promising. any opinions? http://www.keywestpaddlesports.com/05_Steady-Sport.asp
