In sailing, the trapeze is a wire that comes from a point high on the mast, usually where the shrouds are fixed, to a hook on the crew member's harness at approximately waist level. The position when extended on the trapeze is outside the hull, braced against it (or an extension of it outwards) with the soles of the feet, facing the masthead, and clipped on by a hook on the trapeze harness. This gives the crew member more leverage to keep the boat flat by allowing the crew member's centre of gravity to balance the force of the wind in the sails.
An additional benefit is the ability to "walk" along the gunwale to balance the boat's trim fore and aft. This is necessary to prevent racing catamarans such as the Tornado from digging the bow into the water, also called pitchpoling, and causing a nosedive and often a spectacular capsize.
Boats may have only one trapeze, such as the 420 and the 29er, where only the crew uses the trapeze. Dinghies, such as the International 14 and the 49er, may have trapeze wires for both the skipper and the crew. The trapeze has several colloquial names such as "the wire" or simply "the trap".
When a boat loses power in its sails, and heels to the windward side, the crew on the trapeze may get dipped in the water if they do not react in time.
Some classes allow footloops on the gunwale to allow those on the trapeze to locate their feet with relative security. This helps to prevent the crew from swinging forward, sometimes round the forestay when the boat decelerates suddenly.
Due to safety concerns, the International Sailing Federation changed the rules in 2004 concerning trapeze harnesses, effective January 1, 2009: "40.2 A trapeze or hiking harness shall have a device capable of quickly releasing the competitor from the boat at all times while in use.” However, the ISAF 2009–2013 Racing Rules of Sailing which took effect January 1, 2009 does not include this provision, so this rule change is postponed.
Quick release harnesses are already widely in use, and make it possible for sailors to unhook themselves from the wire from all angles while it is under tension, thus decreasing the chance of getting trapped underwater or in dangerous conditions. The adoption of quick release harnesses has not been universal due to the reduced reliability of the moving parts; stories of such systems releasing unexpectedly have caused many to shun them in favour of traditional fixed hooks.
There are counterclaims for the origin of the device:
On balance it seems likely that Peter Scott developed Beecher Moore's Bell Rope, which was satisfactory for river use, into the more seaworthy harness used on Thunder and Lightning in its 1938 Prince of Wales Cup success. The modern trapeze developed from there - in spite of some temporary official opposition.
Dinghy sailing is the activity of sailing small boats by using five essential controls:
The Mirror is a type of popular sailing dinghy with more than 70,000 built.
Running rigging is the rigging of a sailing vessel that is used for raising, lowering, shaping and controlling the sails on a sailing vessel—as opposed to the standing rigging, which supports the mast and bowsprit. Running rigging varies between vessels that are rigged fore and aft and those that are square-rigged.
Jack Holt, OBE was a prolific designer of sailing dinghies. His pioneering designs of dinghies using plywood did much to popularise the sport of sailing in the period immediately following World War II.
The 49er and 49er FX is a two-handed skiff-type high-performance sailing dinghy. The two crew work on different roles with the helm making many tactical decisions, as well as steering, and the crew doing most of the sail control. Both of the crew are equipped with their own trapeze and sailing is done while cantilevered over the water to the fullest extent to balance against the sails.
The International 420 Dinghy is a sailing dinghy popular for racing and teaching. The hull is fiberglass with internal buoyancy tanks. The 420 has a bermuda rig and an optional spinnaker and trapeze. It has a large sail-area-to-weight ratio, and is designed to plane easily. It can be rigged to be sailed single-handed or double-handed. The 420 is an International class recognized by World Sailing. The name refers to the boat's length of 420 centimetres.
The Lightning is an American sailing dinghy that was designed by Olin Stephens of Sparkman & Stephens, as a one-design racer and first built in 1938.
In sailing, hiking is the action of moving the crew's body weight as far to windward (upwind) as possible, in order to decrease the extent the boat heels. By moving the crew's weight to windward, the moment of that force around the boat's center of buoyancy is increased. This opposes the heeling movement of the wind pushing sideways against the boat's sails. It is usually done by leaning over the edge of the boat as it heels. Some boats are fitted with equipment such as hiking straps and trapezes to make hiking more effective.
The Fireball is a British sailing dinghy that was designed by Peter Milne as a one-design racer and first built in 1962.
The Laser 4000 is a racing dinghy designed by Phil Morrison crewed by two persons. Its one-design weight-equalised system enables physically differing sailors to compete on a level playing field. It is most popular in Europe, particularly the UK, France and Italy.
The International 14 is a British racing sailboat, crewed by two sailors. The class was established in 1928.
The Merlin Rocket is a 14 foot (4.3 m) dinghy sailed in the United Kingdom. It is an active class, now with over 3700 boats built.
The Laser 3000 is a racing sailing dinghy crewed by two persons with a trapeze for the crew. Launched in 1996, the 3000 was developed from the Laser 2, using the original Frank Bethwaite-designed planing hull combined with a brand new self-draining deck by Derek Clark. Clark also re-designed the rig, using spars and sails from premium proprietary sources and replacing the symmetric spinnaker of the Laser 2 by a larger asymmetrical spinnaker. The gennaker is chute-launched and retrieved using a single halyard line, and is set on a retractable bowsprit. Helm balance and handling were improved using a shorter-footed mainsail with two full-width battens giving a larger roach. A mast with conventional spreaders replaced the now-unusual diamond arrangement of the Laser 2.
The Jacksnipe is a two-man racing sailing dinghy with a single trapeze for the crew and symmetrical spinnaker.
The Laser Vago is a British/American sailing dinghy that was designed by Jo Richards as a one-design racer and first built in 2005.
The Buzz is a sailing dinghy designed in 1994 by Ian Howlett and John Caig and manufactured by Reg White Limited of Brightlingsea as part of the "White Formula" range of boats originally marketed by Topper International Ltd but since 2013 by Vantage Sailing. The Buzz is a double handed racing boat, with a single trapeze for the crewman. The boat has a fully battened mainsail, furling jib and an asymmetrical spinnaker. There have been around 500 boats built. The Buzz is designed to be an easy to sail boat, but it can also be raced competitively.
The B14 is a two man monohull dinghy, designed by Julian Bethwaite. It is recognised as an international class by the International Sailing Federation. The boat was designed in 1984.
ISO is an International Sailing Federation (ISAF) class of two-person sailing dinghy with a single trapeze and an asymmetric spinnaker. The ISO was designed in 1993 by Ian Howlett and John Caig and manufactured by Reg White Limited of Brightlingsea as part of the "White Formula" range of boats originally marketed by Topper International Ltd and since 2013 by Vantage Sailing Ltd. The boat has a fully battened mainsail, jib and an asymmetric spinnaker.
Beecher Moore was a highly influential figure in the development of dinghy sailing in the United Kingdom after the Second World War. He worked for many years with Jack Holt who designed numerous dinghies, and together they did much to make sailing a pastime accessible to the masses.
The lug sail, or lugsail, is a fore-and-aft, four-cornered sail that is suspended from a spar, called a yard. When raised, the sail area overlaps the mast. For "standing lug" rigs, the sail may remain on the same side of the mast on both the port and starboard tacks. For "dipping lug" rigs, the sail is lowered partially or totally to be brought around to the leeward side of the mast in order to optimize the efficiency of the sail on both tacks.
