Abstract
A resilient, shock absorption assembly that mounts between available sail rigging lines and a boat hull. In one assembly, a piston is resiliently biased relative to a housing and contained spring to permit reciprocating movement. Couplers at distal ends of the piston and housing attach to suitable rigging lines and/or the boat. In other assemblies, resilient elastomer cores bias movement of a piston or cable. In another assembly fitted within a main sail boom, a cable biases the boom rigging lines. In still another construction, an “A-shape”, mast replacement framework is secured to pivot from a boat's deck. Resiliently biased cables act as a mast and support a sail boom. One or more separate resilient assemblies can be coupled to the sail. The cable mast and rigging lines are thus made resilient to counterbalance the boat against heeling with the presence of rough water and gusty winds.
