Hi Eric and all, I wrote: >I was reading an article by Kent Ford in a past issue of Paddler magazine >(May/June 1999). The title of the piece is "Make Your Boat Glide". He >talks about how rocking fore and aft and side to side cause considerable >drag on the hull. Kent claims that, "A barely visible wobble or bob, say >one-half inch, is like dragging a coffee cup-sized anchor on each side of >the boat." I'm having a hard time believing this. Could someone enlighten >me please? Eric replied: <<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).>> Kent mentions "rocking fore and aft" but doesn't expand on it for some reason. All he says is, "the hull of a kayak or canoe slows significantly when it bobs front to back, or rocks side to side." He's not talking about any particular boat. There are photos of a couple boats, none of which are slalom boats. It seems to me that a slalom boat might suffer more that other types when it bobs and rocks.
