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 a cunningham and how is it used?
The cunningham controls the fore and aft position of draft in the mainsail or genoa and works together with the traveler, mainsheet, outhaul and vang to optimize sail shape and increase boatspeed. Cunningham controls lead to the crew to encourage adjustment as wind speed changes.
What is the difference between a cunningham and a boom vang?
1. 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 topping lift on a sailboat?
The topping lift (more rarely known as an uphaul) is a line which applies upward force on a boom on a sailboat. 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.
Is the cunningham the 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 then passed through a cringle in the luff of the sail near the foot, but above the tack, and then led down on the other side to a fitting on the mast or boom or on deck.
How do you heave too?
To heave to, trim the storm jib to windward, force the bow off the wind and then tie the helm down to maintain a slightly upwind. The boat will seek an angle approximately 60 degrees off the wind and will then proceed forward at one or two knots.
How do you rig a boom vang?
To install a boom vang on a C-22 or similar sailboat:
- The vang should be installed at a 45 degree angle between the mast and boom.
- Measure the same distance along the bottom side of the boom from the aft side of the mast and make a pencil mark.
What is a traveler on a sailboat?
The mainsheet traveler is a device that allows for changing the position where the mainsheet tackle connects to the boat. The traveler is typically mounted either in the cockpit or on the cabin top for mid-boom sheeting.
Who adjusts the sails on a ship?
The running rigging has three main roles, to support the sail structure, to shape the sail and to adjust its angle to the wind.
What is a sail flattener?
The distance from the water line to the bottom of a boat’s keel.When the line is tightened, the grommet is pulled down to the boom and out as far as the sail can stretch. Also called “flattener”. Foot: The bottom edge of a sail.
Where is the cunningham on a sail?
The Cunningham tackle attaches to the luff of the main just above the tack. 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.
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.
Is a topping lift necessary?
It is important to note that with an adjustable topping lift it is essential that this line is released once the mainsail is hoisted, allowing the sail to pull taut. In this position, the mainsail can achieve an effective shape and can be trimmed nicely for sailing at different points of sail.
Do all sailboats have a topping lift?
Most sailboats have a traditional topping lift to perform this function, whole some boats use a newer rigid vang to hold up the boom. Shown in this photo is an adjustable topping lift from the outboard end of the boom to the masthead.
When should I adjust my topping lift?
When the sail is raised, the topping lift should be adjusted to take out any slack in it while taking care to not over-tighten it. When the mainsail is reefed, the boom will rise to meet the new clew, this will also induce a lot of slack into the topping lift.
What does the downhaul do?
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 is downhaul used for?
A downhaul is a common term used in reference to a rope, which is usually a part of the rigging on a boat, that is used to haul down or to assist in hauling down a sail. With it, a downward force is applied on the spar or sail. It is common for this rope to be attached to the spinnaker pole.
What is a clew on a sailboat?
Clew – The corner where the leech and foot connect is called the clew on a fore-and-aft sail. On a jib, the sheet is connected to the clew; on a mainsail, the sheet is connected to the boom (if present) near the clew. Clews are the lower two corners of a square sail.
What does reaching mean in sailing?
When the wind is coming from the side of the sailing craft, this is called reaching. A “beam reach” is when the true wind is at a right angle to the sailing craft. A “close reach” is a course closer to the true wind than a beam reach but below close-hauled; i.e., any angle between a beam reach and close-hauled.
What is heave min?
In sailing, heaving to (to heave to and to be hove to) is a way of slowing a sailing vessel’s forward progress, as well as fixing the helm and sail positions so that the vessel does not have to be steered.
Can you stop a boat in the middle of the ocean?
Can you drop anchor in the middle of the ocean? The answer to that is ‘no’. Anchoring in the middle of the ocean is not possible due to the depth. In order to maintain good holding, you want at least 7 times more line out than there is water underneath your boat.
