Larry Samuels (and also Dennis Farrell) were nice enough to point out to me
the keel retaining bolt/rod is actually in double shear. Larry explained to
me that since the keel retainer has to be sheared twice, it can actually
take twice the load to shear it. In other words, the figures I give for
shear strength are actually 1/2 the real shear factor. The 5/16 keel pin
calculated to shear at 1000 lbs will actually shear at 2000 lbs because it
goes through the trunk two times, one on each side.
Also the trunk is not flush to the keel so the pins are not in perfect
shear.
My thanks to Larry and Dennis for catching this.
