Here is my review of having the kayak on a LAKE. Winds (10-15mph), very minor boat traffic (water still cold, 50 degrees).
I have finally had the kayak out on the water a few times now and would like to add my 2 cents worth of the experience I have when comparing it to the 12'-8" I had.
First off I do notice that the FS128T IS a little more stable. I forgot what I was doing, but I leaned to the side, and quickly had to upright myself to avoid rolling. Once I got that pivotal point out of the way, I was fine after that. That was a close call. But it is still stable, I just found out what the limits were unintentionally. This was also with the seat in the higher position.
A lot of people mention that these kayaks are slow. Comparing it to the FS128T, I believe it's faster, and doesn't take much for me to go. You definitely feel the weight difference.
As for paddling and turning. Holy crap, I can turn this kayak on a dime. I really like that. Not much effort to change direction. I was able to go a pretty decent speed as well. I did notice that I had to redirect myself more often. Nothing too crazy, but I see where the tracking comes in to play. Especially when the winds started blowing. I did not use the wind chute, or anchor to hold my position. Might try that next time, especially the chute. See if that would make a difference.
I dropped the seat down in to the lower position and that was definitely more comfortable. Easier to paddle, and obviously felt more stable in that position. In the lower position, it definitely makes it a little harder to stand up. I might install an assist strap, like the FS128T has. That was rather convenient.
I definitely like the shorter length. Everything behind me is easy to access, and I don't need to crawl on the deck just to get something.
Putting the kayak on top of the vehicle is soooo easy. I was really worried about that, but that is working out really well. 50 lbs vs 98lbs = night and day, in a good way!
There's some of the things I've noticed so far. All in all, it's definitely a change. Taking a little getting used to. I think it'll get more comfortable and easier the more I use it. Regardless, no turning back now
