Watson here!
Well... not exactly. More like Frank. As my rough caculations have it - given the variables that: 1. The sail is not the same length as the boom.
2. The point of attachment for the sheeting is not in the center of the boom - affecting the curvature.
But, for a 12' boom with a very noticable deflection of 2.5" the reduction in boom length is only about 0.73".
Keep in mind that the exact position of the point of attachment for the main sheet and of the clew are being roughly but fairly estimated.
Best,
Frank
p.s. If the vang is tight, and the load is more to the front of the boom, will the later part of the boom retain more of its orginal shape? And would this bring curvature more forward?
