One of the many revelations when I first changed over from paddling skis to kayaks was that kayaks came in different volumes (sizes). One size does not fit all.
This means that there were slight variations on models of boats from the same manufacturer.
The most common rule of thumb, and please remember that this is referring to paddling in the early 80's, was that light weight's paddled a Tiger, mid-rangers paddled Cleavers, and us of a heavier build paddled the Cleaver-X. Boat selection was simple!
