Sails, Rigging & Deck Gear

Many of Practical Sailor's previous reports have explored the risks of multihull capsize, and what sailors and designers are doing to reduce this risk, which, though generally low, increases as designers push for more speed. One detail that we have not explored in great depth is the engineering of a “dump line,” which allows the helmsman (or automatic system) to quickly release the mainsheet in case a capsize is imminent. Simon Angus, a Canadian sailboat designer and builder who recently launched a new 40-foot catamaran that fits into a shipping container, has a manual system that involves the clever use of Ronstan’s constrictor textile rope clutches, which allows a person at the helm to quickly release the mainsheet with the swift tug on a parachute cord.
