What is the purpose of a boom vang on a sailboat?
The vang allows vertical adjustment of the boom, and is an extremely important tool to shape the main for speed. Tension the vang to tighten the leech, flatten the sail and bend the mast. Cruisers use the vang to keep the boom from rising when sailing downwind and abraiding the main.
What is downhaul in sailing?
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.
What does boom mean in sailing?
In sailing, a boom is a spar (pole), along the foot of a fore and aft rigged sail, that greatly improves control of the angle and shape of the sail. The primary action of the boom is to keep the foot flatter when the sail angle is away from the centerline of the boat.
What is a boom kicker on a sailboat?
A boomkicker is a modern mechanical device on boats that pushes the boom up by one or more glassfiber rods. If the boom is sheeted in, the rods will bend and produce a force upwards. This provides several beneficial effects for the sailor.
Why do I need a boom vang?
The boom vang (or “kicking strap”) is a system used to control the shape of the sail. It counteracts the upward force of the boom jack and the mainsail by pulling the boom downward. This results in the ability to control the shape of the sail.
Is a kicker the same as a vang?
A boom vang (US) or kicking strap (UK) (often shortened to “vang” or “kicker”) is a line or piston system on a sailboat used to exert downward force on the boom and thus control the shape of the sail.
What is the difference between a Cunningham and a boom vang?
A boom downhaul is used on a boom that connects/attaches to a track mounted gooseneck, track is mounted to the mast. 2. A cunningham is used on a gooseneck that is direct attached to a mast (no track to slide up and down on)…
What is the difference between a downhaul and a Cunningham?
The cunningham differs from a typical downhaul in the way that it attaches to the sail. The system usually consists of a line which is secured at one end to the mast or boom below the foot of the mainsail.
What do you say when the boom swings?
“Jibe-ho” accompanies the start of the boom swing across the centerline. Accidental jibes may occur when running dead downwind and the wind catches the leeward side of the sail.
Why is boom called boom?
“explosive projectile,” originally consisting of a hollow ball or shell filled with explosive material, 1580s, from French bombe, from Italian bomba, probably from Latin bombus “a deep, hollow noise; a buzzing or booming sound,” from Greek. Thus probably so called for the sound it makes.
Can you sail without a vang?
Without a vang, the boom will lift as the mainsheet is eased, opening the leech, and the top of the sail will twist off to leeward, spilling the wind. If you are sailing downwind with the mainsail eased right out, the top of the sail can twist so far off that it is forward of the shrouds.
Do all sailboats have a boom vang?
Not all sailboats have a boom gnav, and those that do often use it as a substitute for a boom vang. Boom gnav systems are most common on small sailboats, where the added lower triangle of a boom vang gets in the way.
What is a Cunningham on a sailboat?
The Cunningham is an adjustment used to tension the luff of the mainsail to move the draft forward, offsetting the wind’s efforts to push the draft aft. Most mainsails come standard with a Cunningham cringle on the luff above the tack.
Is cunningham same as downhaul?
In sailing, a cunningham or cunningham’s eye is a type of downhaul used on a Bermuda rigged sailboat to change the shape of a sail. It is named after its inventor, Briggs Cunningham, a victorious America’s Cup skipper and yacht builder.
What is the fastest point of sail?
Beam Reach
Beam Reach – This is the fastest and easiest point of sail. The windis on the side of your boat (beam) and you’ll sail with your sails outhalf way. Broad Reach – On a broad reach you’ll be heading a bit further downwind, so you will have to let your sails out a bit more.
How do you rig a downhaul?
Rig a Jib Downhaul Line – YouTube
Is it better to tack or jibe?
In a small boat such as the Tech Dinghy, the tack is a safer maneuver so you should start with the tack rather than the jibe. The closest angle you can expect to sail toward the wind is a 45° angle, so to perform a tack you must turn a minimum of 90° to complete the tack.
What do sailors yell?
“Ahoy!” – sailors would use this exclamation among themselves to call out to each other.
What are the three corners of a sail?
The peak is the very top of the sail. The throat is the top front corner of the sail. The tack (noun) is the name for the lower corner of the sail closest to the mast. Not to be confused with a tack which describes which side of a sailboat the wind is coming from while under way—port or starboard.
What holds up the boom on a sailboat?
topping lifts
Part of the running rigging, topping lifts are primarily used to hold a boom up when the sail is lowered. This line would run from near the free end of the boom(s) forward to the top of the mast. The line may be run over a block at the top of the mast and down to the deck to allow it to be adjusted.

What is the best angle to sail?
About the best angle off the wind that most sailboats can achieve is 30 degrees. Any less than this and the wing shape of the sail begins to deflate.
