The Pygmy page has some interesting articles on multi-chine vs hard chine performance, i.e. Coho and Arctic Tern.
John Lockwood's computer studies and research shows about a 3.2% difference in efficiency. That is .128 of a mile at 4 mph.
So after an hour at a brisk paddle, one is a little over 200 yards ahead of the other. Rest stops, gliding to look at scenery, paddle choice, stroke efficiency, taking a drink or snack, drifting off course and correcting, wind and wave conditions equal lots of other variables that have more effect.
If you like the looks of a kayak and it is comfortable, it is probably a good choice to build.
