Hobie 16
The ISAF International Class Hobie 16 (H16) is a popular catamaran manufactured by the Hobie cat, Hobie Cat Company for racing and day sailing. The craft was the driving force behind the popularization of beachcats and was recently inducted into the Sailing Hall of Fame. Introduced in 1971, the Hobie 16 is the second largest boat fleet in existence with over 135,000 boats built to date. The boat is distinctly recognized for its asymmetric "banana" shaped hulls, designed to work without the need for daggerboards so the catamaran could be run up the beach without worry. The rudders kick up automatically by lifting up on the tiller crossbar. Design The Hobie 16 is manufactured in France by the Hobie Cat company, and by the Hobie Cat of America company in the United States. The Hobie 16 normally carries two sails, the mainsail and the jib. There is a kit to allow an H16 to fly a spinnaker but this is only class legal for youth racing.

Bungee Cord
file:Bungee Cord PICT6882a.jpg, Bungee cords equipped with metal hooks A bungee cord (sometimes spelled bungie; also known as a shock cord or an ocky strap) is an elastomer, elastic cord composed of one or more elastic strands forming a core, usually covered in a woven cotton or polypropylene sheath. The sheath does not materially extend elastically, but it is braided with its strands spiraling around the core so that a longitudinal pull causes it to squeeze the core, transmitting the core's elastic compression to the longitudinal extension of the sheath and cord. Specialized bungees, such as some used in bungee jumping, may be made entirely of elastic strands.

Hobart "Hobie" Alter
Hobart "Hobie" Laidlaw Alter (October 31, 1933 – March 29, 2014) was an American surf and sailing entrepreneur and pioneer, creator of the Hobie Cat catamarans, and founder of the Hobie company. He created the Hobie 33 ultralight-displacement sailboat and a mass-produced radio-controlled glider, the Hobie Hawk. Early life Hobart Laidlaw Alter was born and raised in Ontario, California, but his family had a summer house in Laguna Beach, where Alter got into the full array of ocean sports. Career Surfing and skateboarding business During a summer vacation in 1950 Alter began by building 9-foot balsawood surfboards for his friends. He asked his dad to pull the DeSoto out of the family's Laguna Beach, California, garage, and converted the garage into a woodshop for his hobby. Initiated into surfing by Walter Hoffman, he started shaping balsa boards in the early 1950s. When the family's front yard became cluttered with the remnants of surfboard production in 1953, his father mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Outhaul
An outhaul is a control line found on a sailboat. It is an element of the running rigging, used to attach the mainsail clew to the boom and tensions the foot of the sail. It commonly uses a block at the boom end and a cleat on the boom, closer to the mast, to secure the line. The outhaul is loosened to provide a fuller camber or tightened to give the sail foot a flatter camber. Depending on the wind, this will increase or decrease boat speed. Sailboat designer and sailing theorist, Frank Bethwaite Francis Dewar Bethwaite (26 May 1920 – 12 May 2012) was a New Zealand naval architect, author and Olympic meteorologist.racing sailboat, should be knotted and the boom ma ...

Downhaul
The downhaul is a line which is part of the rigging on a sailboat; it applies downward force on a spar or sail. The most common downhaul on a modern sailboat is attached to the spinnaker pole, though this may be referred to as the foreguy in some rigging nomenclature. The term is also commonly applied to the cunningham on the mainsail. In a windsurfing rig, the downhaul is the primary load-bearing line which controls the sail's shape. Modern windsurfing sails incorporate a sleeve for the mast, and therefore do not have a halyard In sailing, a halyard or halliard is a line (rope) that is used to hoist a ladder, sail, flag or yard. The term "halyard" derives from the Middle English ''halier'' ("rope to haul with"), with the last syllable altered by association with the E ... which tensions the top of the sail. The downhaul is tensioned early in the rigging process and is generally not adjustable on the water, and is therefore rather different in use than the downhaul on a sa ...

Sheet (sailing)
In sailing, a sheet is a line (rope, cable or chain) used to control the movable corner(s) (clews) of a sail. Terminology In nautical usage the term "sheet" is applied to a line or chain attached to the lower corners of a sail for the purpose of extension or change of direction. The connection in derivation with the root "shoot" is more clearly seen in "sheet-anchor", one that is kept in reserve, to be "shot" in case of emergency. Fore-and-aft rigs Fore-and-aft rigs comprise the vast majority of sailing vessels in use today, including effectively all dinghies and yachts. The sheet on a fore-and-aft sail controls the angle of the sail to the wind, and should be adjusted to keep the sail just filled. Most smaller boats use the Bermuda rig, which has two or three sets of sheets: * The mainsheet is attached to the boom, and is used to control the mainsail. In a rig with no boom on the mainsail, the mainsheet would attach directly to the mainsail clew. A mainsheet is a line con ...

Tiller
A tiller or till is a lever used to steer a vehicle. The mechanism is primarily used in watercraft, where it is attached to an outboard motor, rudder post, rudder post or stock to provide leverage in the form of torque for the helmsman to turn the rudder. A tiller may also be used in vehicles outside of water, and was seen in early automobiles. On vessels, a tiller can be used by the helmsman directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel. Rapid or excessive movement of the tiller results in an increase in drag and will result in braking or slowing the boat. Description A tiller is a lever used to steer a vehicle. It provides leverage in the form of torque to turn the device that changes the direction of the vehicle, such as a rudder on a watercraft or the surface wheels on a wheeled vehicle. A tiller can be used by directly pulling or pushing it, but it may also be moved remotely using a whipstaff, tiller lines, or a sh ...

Cam (mechanism)
A cam is a rotating or sliding piece in a linkage (mechanical), mechanical linkage used especially in transforming rotary motion into linear motion. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an Eccentric (mechanism), eccentric disc or other shape that produces a smooth reciprocating (back and forth) motion in the ''Cam follower, follower'', which is a lever making contact with the cam. A cam timer is similar, and these were widely used for electric machine control (an electromechanical timer in a washing machine being a common example) before the advent of inexpensive electronics, microcontrollers, integrated circuits, programmable logic controllers and digital control. Camshaft The cam can be seen as a device that converts rotational mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trapeze (sailing)
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. Some 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 ...

Dolphin Striker
A dolphin striker (an older term for a martingale boom or simply a martingale; sometimes called a striker) is a small vertical or near vertical ancillary spar spanning between the bowsprit and martingale thereby redirecting the tension in the forward end of the martingale slightly more vertically. This vertical component is necessary to more effectively oppose the forestays' mostly upward tension on the forward end of the bowsprit than would be the case in the absence of the dolphin striker. Around 1813 some large sailing vessels experimented with double strikers: these had two downward-pointing spars forming an inverted ''V'' in the middle of the bowsprit. However, the practice was short-lived as it did not seem to provide any additional benefit. The dolphin striker's length was typically half the length of the spritsail yard or, when spreaders were used, the same length as one spreader. On a catamaran such as the Hobie 16 and the Tornado where the mast is stepped on a beam be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crossmember
A crossmember, also known as a K-frame, is a structural component that is transverse to the main structure of a vehicle. In the automotive industry, this term typically refers to a steel component, often boxed, that is bolted across the underside of a monocoque (unibody) motor vehicle to support the engine An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power ge ... and the transmission. For the suspension of any car to operate correctly, ensuring proper handling and maintaining body panel alignment, the frame must be strong enough to cope with the loads applied to it. It must also resist deflection and have sufficient torsional strength to withstand twisting forces. A "K" member is a specific type of crossmember found in vehicles with longitudinally-mounted engines. It contains the engine ...
