What is a lug on a boat?

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.

Where did the lug sail originate?

The lugsail was extensively used in the Bay of Biscay and thereabouts, and experts say that it originated on the Basque coast. This rig never took hold among deep-sea ships, yet was used almost exclusively among smaller vessels, at least from the sixteenth century on.

Where did lug sail technology originate in Asia?

Today, the batten lug is found almost exclusively in East Asia, and found there in great numbers. Its prevalence in China, and its virtual absence elsewhere in the world, has given rise to the natural assumption that the batten lug sail must have been an innovation of strictly Chinese origin.

How do you tack a dipping lug sail?

The traditional method for tacking the dipping lug is to lower the sail as she comes through the wind, cast off the tack tie down, carry the sail and yard around to the new leeward side of the boat, reattach the tack line and re-raise the sail.

Why are triangular sails better?

Triangular sails make it easy to navigate using a half wind which helps the boat maneuver. As wind passes around the airfoil, negative pressure is induced out front of and on the leeward side of the sail. This causes surrounding air to rush into the sail, which helps propel the boat.

What is the mizzen sail?

A mizzen sail is a small triangular or quadrilateral sail at the stern of a boat. A steadying sail is a mizzen sail on motor vessels such as old-fashioned drifters and navy ships (such as HMS Prince Albert). The sail’s prime function is to reduce rolling rather than to provide drive.

What is a junk rigged sailboat?

The junk rig, also known as the Chinese lugsail or sampan rig, is a type of sail rig in which rigid members, called battens, span the full width of the sail and extend the sail forward of the mast.

Are junk sails good?

When running and on a broad reach, junk sails are faster than a similarly sized Bermuda sail without a spinnaker. Bermuda sails collapse often downwind, which is called a stall, due to the sails lack of rigid battens supporting it.

What were Chinese junk sails made of?

Made from wood, junks were boats with flat bottoms. The square rigged sails were mounted on bamboo poles that can be closed together. The sails were considered the main part of the boat, which also facilitated the boat with great speed. However, unlike other types of boats, junks don’t have any keel (flat bottom).

What is a dipping lug?

Definition of dipping lug : a lugsail in which the tack is made fast to the deck forward of the mast and the yardarm must be dipped and hoisted again on the other side of the mast in tacking.

What is a drifter sail?

Drifters are a hybrid designed specifically for cruising sailors. Its wind range is from 1-15 knots when the apparent wind angle is 30-90 degrees. It can be used on a run when set wing-and-wing with a whisker pole. A Drifter is even easier to use than a cruising spinnaker since the sail has the same profile as a genoa.

Why do boats have 2 sails?

The wind that sweeps around the first sail can be easily caught by the second and add to the overall speed of your sailboat. To easily demonstrate this, take down that extra sail if possible.

What is a battened sail?

On sailboats, a sail batten is a flexible insert in a sail, parallel to the direction of wind flow, that helps shape its qualities as an airfoil. Battens are long, thin strips of material, historically wooden but today usually fiberglass, vinyl, or carbon fiber, used to support the roach of a sail.

What is a cat rigged sailboat?

A boat or yacht that is Cat-rigged has a single mast, stepped well forward, carrying a single fore and aft sail, behind the mast. A boat that is cat-rigged can also be described as having a Una rig. Laser dinghies are cat-rigged, as are Finn dinghies, Optimists, many Freedom Yachts and many traditional fishing vessels.

Why are junk sails red?

The reddish-brown color of the traditional junk sail is a result of an additive, what’s known as “tanbark.” The woven grass (then later canvas) sails were “tanned” to protect them from the elements—dipped in tannins extracted from the bark of oak trees.
