Shock load is the result of arresting the motion of the swinging boom (propelled by the wind in the sail). If there is no motion (the preventer being properly snug), then the limit of motion is the stretch in the line used for the preventer (LINE WITH STRETCH HAS A CUSHIONING EFFECT HERE) and the shock load is not much higher than the force on the sail before the gybe.

If you are connecting the boom to a block on the genoa track as a preventer, there shouldn't be much tension at all......what am I missing? Rob Abbott AZURA C&C 32 - 84 Halifax, N.S.
