I have been paddling an Ocean Kayak Prowler Trident 15 for 2 years. I have 11 kayaks. I have a Malibu extreme, 3 other models of Ocean Kayaks and a wilderness. I have paddled some Hobie kayaks too. I fish off the beach mostly in the summer and fish bays during the rest of the year. I guide eco-tours in everything from little tiny creeks all the way out to the beach. If you are going to be in open water it is the bomb. If you are going to paddle creeks, I would suggest something shorter. I will occasionally let some of my larger customers paddle mine, just for comfort reasons, and the fact that the weight capacity is larger. I have noticed that most of the taller guys ( over 6') dont look reall comfortable with the leg room. Its a surprisingly short cockpit i guess. I am 5'9" and my legs are quite comfortable in it.
The T-15 tracks well, it handles the rolling waves well, very stable ( i can stand up fairly easily if I need to) It is not a fast ride, and I am often behind my customers in some of the smaller kayaks, but I am not about speed, so I don't mind.
I hope that this info has been helpful.
