I know we beat this subject up not that long ago, but I got a new datapoint yesterday which I slipped onto our local Chesapeake Paddler Association (CPA) list, and it has generated some interest. So, for PaddleWise, an interesting factoid --- Was speaking with a Yakima customer service rep yesterday about kayak racks. He gave me what sounded like a standard "please always use bow and stern lines" disclaimer, which grew into a short discussion. Apparently Yak did some tests recently, and discovered that when a vehicle with a sea kayak on the roof passes a semi-truck heading the opposite direction on a two lane highway, the wind blast created generates a 200 pound instantaneous vertical lift on the boat's bow. That's a bunch of pounds now trying to lever your boat out of its straps or, as Chuck Sutherland pointed out this morning on his CPA response, the forward rack and boat off the roof! He was not speaking hypothetically, apparently. Something to think about if you don't like taking the extra time or effort to tie down the loose ends!
