I am 5'8" and 225, and it fit me well. My legs are short enough the footpegs fit well, and it had the optional seat which was very comfortable. Ten minutes into the trip, the whitecaps started, and it was great fun surfing the waves. Twenty minutes into the trip I ducked into a quiet bay out of the wind. I then headed south into the wind back to the ramp. For 20 minutes I worked very hard for almost no gain, perhaps one mile an hour. If I had not had to be back in one hour, I would have just stayed out and played. Halfway back, the waves reduced to non-whitecap status, and I was able to increase to 3 or 4 mph.
The complaints I have are minor, with the largest being how wet the ride was, but one should expect that in a SOT. If I could find a kayak 2 feet longer and 2 inched narrower, one would have much more speed and not much less stability. I am seriously considering an RTM Disco, affordable and fast. But for a 12'6" kayak, the Cayman was fine and I would buy one as a backup if the price is right. If one has trouble tracking in this kayak, consider your paddling style rather than blaming the kayak.
I looked around for another boat looked to Perception and didn't like what I saw, looked at Islander boats, but just didn't like the shape, lack of room, and the flatness of the boat. I also looked at cobra, but didn't like all the hatches, my kahuna had alot of hatches and did they leak!
I was just looking and found my cayman, this was the first boat that I found that I felt comfortable with look wise, shape, depth, and storage. The guy at the shop couldn't give me alot of info so I bought it. I like the boat I paddle the open ocean on a regular basis as well as surf when it's good and have even done some flat water paddling and didn't have any problems. Over all I like the boat I bought. I know this may sound alittle silly but the color is really cool as well.
