I just purchased the Fenn Swordfish after trying several others, (Epic V-8, V-10 sport, Fenn Mako XT). There was definitely a feel and stability difference between them all. To start with, the Epics are heavier and built for larger paddlers. I am 5'8", 160 pounds a very fit. When I sit in the Epics there is way to much extra space, (look at the size of the company owners, they are large guys and they make Surfski's to fit people their size), and I would require lots of padding to make them fit right.
The Swordfish fit me with no padding required. It's a little less stable but a lot faster on both flat water and the ocean and it turns much better than the other Surfskis. The more I paddle it the more stable it is becoming and for an intermediate paddler it is a great Surfski to grow into, versus growing out of.
The build quality is excellent, these boats are made in South Africa. As far as looks go the Swordfish is beautiful, I wouldn't want to see the guys wife who stated below that it's ugly, he really needs to see the optometrist.
