The Commander is so stable I am able to stand and fish at will. It tracks well and is fairly quick to paddle. The seat is comfortable but I rarely use it as I often paddle from the perch position. The one thing I would add if I designed it would be a small watertight compartment--I use a waterproof bag for my wallet, keys etc.
This yak is a lot like the Ultimate but it sits a little higher in the water and has better displacement. I also think it is more stable (the Ultimate is still very stable). All in all if u could only have one yak this would be my choice.
For a 10ft yak it is fairly quick. I am 5'10" and weigh 190lbs this yak has no problem with my weight even when loaded down. The seat is not bad but not good. I simply put a padded seat on top of the stock seat and I paddle in comfort. I put a small skeg on it and I love this small yak now.
If u are looking for a yak to fish or hunt out of this one needs to be on your list. Its light, rugged and fairly quick. U will need a skeg or rudder but the yak is well made.
