NO MORE STRESS -- Whether tied to a dock or mooring, at anchor or towing a dinghy, lines and chains create enormous stress on cleats, chocks, fairleads and related fittings, especially when suddenly jarred. ShocklesT from Davis Instruments is a patented line of simple, innovative devices that absorbs the damaging shock loads placed on a boat's hardware and cordage from wakes, chop, waves and tidal surges. They make for a safer, more comfortable boating experience.
