I just bought a 10' Nucanoe. I only took it out 1 time so keep that in mind. Mostly I'm comparing it to my Ultimate 12.
Much more stable and comfortable than the Ultimate 12. I got a padded swivel seat (any boat seat fits). I forgot how nice it is to fish out of a swivel seat. Plus you're elevated above the floor by almost a foot. More room than the Ultimate 12. Paddling position seems very comfortable because you can hold your hands low.
Heavy, 59 pounds plus luxury seat. I'm glad I got the 10' model. It's 18 pounds lighter. Unless you want to stand or fish with 2 people I'd go with the 10' model. I'm returning the cart that's made for the Nucanoe. It's easy to attach but it doesn't support the weight of the boat. I'm ordering a center kayak cart, maybe a wheeleez tuff tire cart. It seems slower paddling than my Ultimate 12, but I'm not sure by how much. I'll know more when I take both boats out at the same time.
