Again, how
does a longer kayak "overall" not have a longer waterline for
the same type hull

The original poster said nothing about "same type hulls." He
provided two overall lengths and asked for an assessment of
how the speed would compare. I correctly stated that one cannot
determine that from the information on overall length.

But for a given
hull design, it still looks to me that that will be the major
factor according to the sites I posted.

You're ignoring the data on the graph. The data comes from
Sea Kayaker magazine and clearly shows that there is no
correlation between overall length and resistance. Why do
you keep insisting that there is?

No, I'm posting web sites that state the opposite of you, not MY
opinion. Which of course you have snipped.

Try reading a book on the hydrodynamics of hulls. C.A. Marchaj's
"Sailing Theory and Practice" is a good one. You can also stop
assuming that overall length and waterline length are interchangable.

I was seriously asking for data.

I gave you some. It shows that there is no correlation between
resistance and length for 24 common sea kayaks that have been
reviewed in Sea Kayaker magazine.
