A boomkin, bumkin, or bumpkin is a short spar that may project either fore or aft on a sailing vessel, depending on its function. Traditionally, it was a strong, usually wooden spar extending forward over the bow of a Western sailing ship holding a block through which the tack of the foresail was passed; on some modern sailing yachts with long main booms it is a short spar extending aft from the stern anchoring a central backstay. [1]

Contents

Historically, boomkins were employed in pairs, one on either side of the vessel, often canted downwards over the main head-rail. Originally butted at their inboard ends against a knighthead, bolting prevailed since the end of the 18th century.

They are not to be confused with catheads, heavy wooden beams on either side of a traditional vessel's bow angled forward at roughly 45 degrees which support the ship's anchors when being raised or lowered.

History

Traditional boomkins found on English sailing vessels gradually evolved from 1710 until around 1850. [1]

Rigging Ropes, cables and chains which support masts of sailing ships

Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—standing rigging, including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are attached—the running rigging, including halyards, braces, sheets and vangs.

Sailboat Boat propelled partly or entirely by sails

A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture.

Sail plan Description of the specific ways that a sailing craft is rigged

A sail plan is a description of the specific ways that a sailing craft is rigged. Also, the term "sail plan" is a graphic depiction of the arrangement of the sails for a given sailing craft.

Yawl Type of sailboat

A yawl is a type of boat. The term has several meanings. It can apply to the rig, to the hull type or to the use which the vessel is put.

Tall ship Large, traditionally rigged sailing vessel

A tall ship is a large, traditionally-rigged sailing vessel. Popular modern tall ship rigs include topsail schooners, brigantines, brigs and barques. "Tall ship" can also be defined more specifically by an organization, such as for a race or festival.

Backstay

A backstay is a piece of standing rigging on a sailing vessel that runs from the mast to either its transom or rear quarter, counteracting the forestay and jib. It is an important sail trim control and has a direct effect on the shape of the mainsail and the headsail. Backstays are generally adjusted by block and tackle, hydraulic adjusters, or lines leading to winches.

Maritime flag Flag designated for use on ships or at sea

A maritime flag is a flag designated for use on ships, boats, and other watercraft. Naval flags are considered important at sea and the rules and regulations for the flying of flags are strictly enforced. The flag flown is related to the country of registration: so much so that the word "flag" is often used symbolically as a metonym for "country of registration".

Cutter (boat) Type of boat

A cutter is a type of watercraft. The term has several meanings. It can apply to the rig of a sailing vessel, to a governmental enforcement agency vessel, to a type of ship's boat which can be used under sail or oars, or, historically, to a type of fast-sailing vessel introduced in the 18th century, some of which were used as small warships.

Gaff rig Sailing rig configuration

Gaff rig is a sailing rig in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar (pole) called the gaff. Because of the size and shape of the sail, a gaff rig will have running backstays rather than permanent backstays.

Running rigging Lines that control sails

Running rigging is the rigging of a sailing vessel that is used for raising, lowering, shaping and controlling the sails on a sailing vessel—as opposed to the standing rigging, which supports the mast and bowsprit. Running rigging varies between vessels that are rigged fore and aft and those that are square-rigged.

Mast (sailing) Pole used in rigging of a sailing vessel

The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed.

This is a glossary of nautical terms; some remain current, while many date from the 17th to 19th centuries.

Full-rigged ship Sailing vessel with three or more square-rigged masts

A full-rigged ship or fully rigged ship is a sailing vessel's sail plan with three or more masts, all of them square-rigged. A full-rigged ship is said to have a ship rig or be ship-rigged. Such vessels also have each mast stepped in three segments: lower mast, top mast, and topgallant mast. Other large, multi-masted sailing vessels may be regarded as ships while lacking one of the elements of a full-rigged ship, e.g. having one or more masts support only a fore-and-aft sail or having a mast that only has two segments.

Gunter rig is a configuration of sail and spars used in sailing. It is a fore and aft sail set abaft (behind) the mast. The lower half of the luff (front) of the sail is attached to the mast, and the upper half is fastened to a spar which is approximately vertical and reaches above the top of the mast. This spar is called a "yard", but it is common for some to confuse it with a "gaff". The overall shape of a gunter sail is roughly triangular, so having a superficial resemblance to Bermuda rig.

Stays (nautical)

Stays are ropes, wires, or rods on sailing vessels that run fore-and-aft along the centerline from the masts to the hull, deck, bowsprit, or to other masts which serve to stabilize the masts.

Topmast Section of mast on sailing ship

The masts of traditional sailing ships were not single spars, but were constructed of separate sections or masts, each with its own rigging. The topmast is one of these.

Drascombe Family of British sailboats

The word Drascombe is a trademark that was first registered by John Watkinson who applied it to a series of sailing boats which he designed and built in the period 1965–79 and sold in the United Kingdom (UK). They comprised the Coaster, Cruiser Longboat, Dabber, Drifter, Driver, Gig, Launch, Longboat, Lugger, Peterboat, Scaffie, Scaith and Skiff, together with a few other one-offs. They have wide and deep cockpits, adaptable boomless rigs and high bulwarks.

The following outline is provided as an overview of and topical guide to sailing:

The Drascombe Lugger is a British trailerable sailboat that was designed by John L. Watkinson and first built in 1968.
