Peter correctly figured what I figured incorrectly. I tried solving it as a static equation, using the bow as the origin. And didn't come up with the correct answer. that's why I don't have a PE stamp, either! ;) Here's how I should have figured it--I threw away my previous notes, so can't check my (bad) math. Kayak weighs 56 lbs. Force X at the rack, plus force Y at the stern grab loop. X+Y=56 For the sake of easy calculation, I figured a 16' kayak. (4' * X) - (8' x 56) + (16' * Y) = 0 (zero net rotation...equilibrium) X + Y - Y = 56 - Y X = 56 - Y (4' * (56 - Y)) - (8' x 56) + (16' * Y) 4'*56 - 4'Y - 8'*56 + 16'Y = 0 224 ft-lb - 4'Y - 448 ft-lb + 16'Y = 0 12'Y = 224 ft-lb Y = 18.67 lb.
