Hi Mark

Even in sail boats a direct scaling would only work for a small change.

Remember the cube rule!!

Factors like Cp Cb start to react badly on a direct scaling.

Further, one knows that in a Kayak a Beam (max) of between 19" & 25/6" is about all you need for a length up to twenty plus feet.

I would think that the sort of specs I would be looking at are a Beam (max) of no more than 24" - Beam wl of about 17"to 18" LOA of about 20' Depth at knees of 13 to 14"

Careful placement of CG around LCB and a draft of no more than 4 or 5 inches.
