RE: [Paddlewise] What a drag

I understand that you couldn't find anything on "changing the heel" but what
about "rocking fore and aft and side to side"? Also, what type of boat was
Ford discussing? If he was talking about a slalom race boat (very low
volume), I would think the already high drag could be multiplied greatly by
a side-to-side rocking (not a one time change of heel).

I have trouble believing it too. I can find nothing in my stuff that
suggests such a thing and changing the heel such a small amount doesn't
change the form characteristics enough to account for it (sometimes the form
gets improved by heel). Did Ford say where he got the information?
