Is this idea commonly accepted?

Interesting site and good information.

However, they have left out something in their comparison of the 15' and 17'
kayaks. What is the displacement used for their calculations? If those numbers
are for the rated displacement of each kayak (or at least a value somewhere
meaningful inside the range for which the kayak is designed), then the
resistance cannot be directly compared. If you put a big paddler, correct for
the big kayak, in the little kayak, it's wetted surface would increase as would
its drag. It may be the case that under those conditions, the overall
resistance of the larger kayak is less. You have to compare them at the same
displacement to compare them equally.
