Fishboy: I'm a neewbie to the sport and this fall will complete my first year on the yak...most of my launches have been on the surf with some occasional lake peaceful launches.
I have a Tarpon 140 and luv it. Enjoy the handling, speed, and stability...hatches are so...so...
I'm 5'10" and 185lbs. apparently water in the footwells and cockpit is common with weights exceeding 200...therefore this yak is not your choice.
I'm not familiar with the heritage but I'm sure many will recommend the SOT yaks for fishing purposes...I agree. Standby, I'm sure many of the experts will chime in with some advice.
PS recommend checking out www.kayakfishingstuff.com
where you'll find lots of useful info about various yaks including personal yak reviews.
