I've borrowed a friend's Vesper (no skeg) a few times. I'm 6'2" and 165. Once I squeezed in, I fit fine (but it wasn't like I spent hours in this kayak).
Tracking - Oh, but the tracking was miserable. After a few powerful strokes, it would pull to the left and it took several left only strokes to get it back in line. Then it would go to the right....
I wouldn't own this thing without adding a skeg. Maybe it is a later one with the worn mold tooling.
