The seat can be used in two positions, high and low. I usually keep it in high position, unless I need more power for going against current or tide. The seat is the most comfortable kayak seat I have ever placed my tail end on...and it stays dry. The ability to stand for sight fishing or just to stretch out is amazing. You can use a strap to help yourself stand up but I have found if you have the seat in the high position you can just stand up.
The stand up bar was useful in the beginning before I came to realize how stable the boat is. Sort of nice to lean against when taking a picture but am considering taking it out as it sometimes gets in the way.
The kayak moves and tracks well on the water. It is very maneuverable and has a decent glide after your last stroke. But, do not expect to win any races with it. To pay for the stability you have to give up speed. In any group I have been with on the water I will be tail end Charlie. But to me, that is a price I am willing to pay for feeling comfortable in my kayak.
My only area of discomfort with this kayak is the weight. I went into it knowing it was heavy, about 100 pounds, and it is just difficult to move around on land. I have good racks on my car and have to put a blanket on the back of the car to slide it up onto the racks. It is easier getting it into the back of a pick up truck but is just generally cumbersome on land. If your launch point is a good distance from where you park then I suggest you get some wheels for it.
Overall, this is a great kayak for someone who enjoys a day of fishing or just a comfortable day on the water!
