What is luff wire?
The wire in the luff of the sail (usually a #6 luff tape on smaller 26' boats) is for feeding the sail into a foil of a roller furler. If there is a furler on your forestay I cannot imagine how you would attach hanks without removing it and the sail may not furl very well around the foil with hanks along the luff.
What is the advantage of a head foil on a boat?
Instead of having an increase in drag with increasing speed—contrary to what happens in traditional boats due to pressure drag—the hydrofoils provide a more efficient way of cruising. Decreasing the drag increases speed and fuel efficiency.
What is a head foil sailing?
Headsail Foils are used to provide a lightweight solution for keelboat racers for protection of the headstay sytem. Headsail foils available at MAURIPRO Sailing feature high strengh, lightweight and impact resistant material tubing.
What is the difference between a head sail and a jib?
Your headsail connects from the bowsprit or the deck by a rod, wire, or rope, keeping the sail in one position. Depending on the shape of your headsail, it could be referred to as a jib. This is a specialty staysail (a type of headsail) that goes in front of your sailboat's mast. One type of jib is a genoa sail.
How does a self furling jib work?
In this roller furling system, the jib is hoisted in a groove, but when not in use is furled around the headstay, rather than lowered. To furl the sail you simply pull on a line that leads from a drum at the base of the jib aft to a winch near the cockpit, which rotates the whole headstay, rolling up the jib.
How do you fit a furling jib?
Attach the furling drum to the attachment point and then attach the jib tack to the top plate on the furling drum, attach the head of the sail into the top swivel forks and then attach the halyard to the top swivel with a shackle. Hoist the sail and tension the luff.
How do foil boats work?
Foils work in a similar way to aircraft wings. In simple terms, as they move through the water they deflect the flow, which exerts a force on the foil. If that force is upward, the faster they move, the greater the lift.
How do boats stay up on foils?
Physics dictates that the faster velocity over the top of the foil also means lower pressure. With higher pressure on the bottom surface of the foil an upward force is produced, which in turn lifts the boat's hulls out of the water.
Is a hydrofoil worth it?
Adding a hydrofoil to an outboard does provide a performance boost much of the time. ... On a 16 footer with a mid-sized outboard and no tabs, for example, a hydrofoil will usually level out the ride by forcing the stern up and the bow down, and will end or greatly reduce porposing.
What is a tuff luff?
Tuff Luff Aero represents a major evolution of slotted headstay systems. Its unique aerodynamic shape provides at least 9% more lift. ( download sell sheet PDF) Faster wind reattachment to the sail with less turbulence is also a benefit of this patented teardrop shape.
What is a Yankee jib?
A Yankee sail is a jib with a high-cut clew of about 3' above the boom. A higher-clewed jib is good for reaching and is better in high waves, preventing the waves crash into the jibs foot. Yankee jibs are mostly used on traditional sailboats.
What is a 100% jib?
Jibs and Genoas are triangular sails which are affixed to a stay in front of the mast. ... Jibs are typically 100% to 115% LP and are generally used in areas with heavier winds. The smaller area of a jib allows it to be able to perform more efficiently in greater wind speed without the need to furl away sail shape.
What is a code zero sail?
A code zero is strictly a downwind sail.
A code zero is often classified as a spinnaker in terms of racing, hence the restriction on the length of the mid-girth, but it's not a true downwind sail. If you're going downwind, you'll use either a symmetrical or asymmetrical spinnaker.
Can you reef a roller furling jib?
With a furler, the genoa can be reefed or stowed from the safety of the cockpit without the physical effort of dragging sails onto the foredeck, so a small crew can sail a large boat, or a moderate size boat can be single- handed.
What is the difference between a jib and a genoa?
Colloquially the term is sometimes used interchangeably with jib. A working jib is no larger than the 100% foretriangle. A genoa is larger, with the leech going past the mast and overlapping the mainsail. ... Working jibs are also defined by the same measure, typically 100% or less of the foretriangle.
How long should my jib sheets be?
The rule of thumb with jib sheets is 1.5 times the boat length. Jib sheet length is governed by the lazy sheet, which needs to be long enough to reach the lazy winch with slack, and have a bit to spare.
