Identify at least 15 parts of a sailboat.

The names of the parts of a sailboat can be broken down into three sets of terms:

Parts of the sail
Parts of the rigging
Parts of the boat

Parts of the sail.

Battens: Plastic or wooden slats inserted in the leech of the mainsail to help stabilize back edge.

Clew: The lower aft corner of the mainsail. The clew is located where the leech and the foot intersect.

Cringle: A grommet or metal ring in a sail though which a line is usually attached.

Foot: The bottom edge of a sail. The foot of the sail is between the clew and the tack.

Grommet: A stainless steel ring within the clew, tack, or head of the mainsail. Used to connect a control line. Also known as cringle.

Head: Top of the Sail.

Jib: The sail between the forestay and the mast. Also called the headsail. There are several sizes of Jibs.

Leech (leach): The aft or back edge of the sail. Lies between the clew and the head.

Luff: The forward edge of the sail or the flapping of a sail when it is not trimmed properly.

Mainsail: The sail aft of the mast which is attached to the mast and the boom.

Roach (or roach line): An imaginary straight line between clew and head of the mainsail. Sail battens extend the leech of the mainsail beyond the roach line.

Spinnaker: A large balloon sail attached to the mast at the front of the boat. It is used when sailing directly downwind (running with the wind).

Tack: The front lower corner of the sail (same word used to describe point of sail)

Parts of the rigging.

Backstay: A line or cable which supports the mast from the stern of the boat.

Bail: A sturdy steel strap on the aft portion of the mast base to which the boom is connected.

Block: A device used to change a line's direction (nautical term for pulley).

Boom: The horizontal spar which extends aft (backwards) from the mast to which the foot of the mainsail attaches.

Boom Topping Lift: A line which extends from the boom to the mast. Supports the boom when the mainsail is taken down.

Boom Vang: A line which places downward tension on the boom.

Chain Plate: A metal plate to which a shroud is attached.

Cleat: A metal or plastic device used to secure a line. There are many types of cleats.

Cunningham: A line connected to the tack used to extend the luff of the mainsail downward toward the deck.
Forestay (Headstay): A line or cable which supports the mast from the bow of the boat.

Gooseneck: A universal joint between boom and mast. The gooseneck attaches to the bail of the mast.

Halyard: A line (rope) used to raise a sail. Use a bowline to tie the head of the sail to the halyard

Mast: The main and highest spar in the center of the boat to which the jib and mainsail are attached.

Outhaul: Places backward tension on the clew of the mainsail. When tightened it will flatten the lower one-third of the mainsail.

Painter: A line used in securing your boat dockside or to accept a tow.

Reefing Line: A line used to shorten the sail.

Sheet: The chief line which is used to adjust a sail against the force of the wind. The mainsail has one sheet. The jib has two, a working (windward) sheet and a lazy (leeward) sheet.

Shroud Lines: Lines or cables which give lateral (side to side) stability to the mast.

Spar: Any pole or mast to secure rigging or sails to.

Spreaders: Horizontal spars which spread the shrouds from the mast.

Step: Portion of the hull that the mast rests upon. Also used as a verb to describe mating mast and hull... as in "Could you help me step the mast?"

Winch: A device used to tighten a line.

Parts of the boat.

Autobailer: A mechanism that (when open and boat is underway) drains water from the cockpit.

Beam: The boat's greatest width.

Bilge: The part of the hull below the cabin's floor, the lowest part of the boat.

Bow: Front of the boat.

Cockpit: The interior of the boat.

Daggerboard: The removable "keel" of your boat. The daggerboard makes sailing at an angle to the wind direction possible. The blunt edge of the daggerboard faces forward.

Daggerboard well: Also called the "trunk" or daggerboard slot. Narrow opening that daggerboard is inserted into.
Deck: Top of the boat which covers the hull.

Gudgeon: A stainless steel strip attached to the outer wall of the transom. Mates with the pins (pintels) of the rudderhead.

Gunwale: Upper surface of a cockpit sidewall.

Hull: Body of the boat.

Pintel: A stainless steel pin located on the forward edge of the rudderhead. The rudders pintels are inserted into the transom gudegons to mate transom and rudder assembly.

Port: The boat's left side.

Rudder: A control surface located behind the transom. Used to steer your boat. Push the tiller to the left and the rudder goes right.

Rudderhead: A metal housing that connect rudder, tiller, and transom. A kick-up rudderhead is designed to allow the rudder to "kick-up" or hinge rearward upon striking bottom while sailing.

Stern: Back of the boat.

Starboard: The boat's right side.

Tiller: A spar attached to the rudder. If you turn the tiller to port the boat will go to starboard.

Transom: The aft (back) wall of your boat.

This illustration shows a number of parts of a small sail boat.
