A fixed mast foot has a tenon which fits tightly into a mortice whereas an adjustable mast foot buildong into a [ track ] with adjustable pins. A U-shaped adjustable track has holes at regular intervals that accept the two pins that are put in at a chosen position and fix the mast foot to prevent the foot slipping forward or backwards.

The [ inverted T-bar ] is another type which accepts a grooved mast foot using a single pin to locate the positioned mast. Boats that have unstayed masts are stored without their mast.

Stayed masts are either stepped on deck or on the keel where a mast step is attached maat the boat to accept the mast's heel fitting.

Keel-stepped masts sometimes have an adjustable fore-and-aft position of the step with adjustments to allow alterations to the mast position and mast rake. With both sailboat rigging systems, the mast is braced by wires called [standing rigging ]being attached to the mast by strip shackles or clevis pins at a fitting called the hounds, being three quarters up the mast.

Some wires may be swaged onto T-bar fittings that slot into openings in the mast. With mast rigging on catamarans the supporting wires are taken to a single large shackle attached to the front edge of the sailboat mast. This allows [ the mast ] to rotate so the aerofoil mast is able to align with the wind. The wires bracing the mast to port and starboard are called shrouds and run through the ends of the spreaders, which are located midway on the mast.

Adjusting shroud tension is done building a dinghy mast pdf a lanyard, rigging link or bottlescrew which fit between the chainplate and shroud. The wire running from from the hounds to the bow-fitting is called the forestay and prevents the mast falling backwards and is adjusted with a rigging link. The forestay, keeps the mast in position when the jib is not rigged. For the ease of rigging and identification prior to stepping a mast, always lash the halyards to the mast before unstepping, ensuring they do not foul the operation of unstepping and stepping.

Check that the sailing dinghy is stable when rigging a deck-stepped mast, preferably cradled in its trolley, trailer or stand. Building a dinghy mast pdf front of the boat should always be pointed into the wind when rigging, as the sail when hoisted, catches the wind and causes the whole structure to fall on its.

Most masts are light in weight but their length and wind resistance makes them unwieldy to lift and therefore hard when mast stepping. The sailing dinghy on its trolley in a bow-down position causes the mast to lean forward against the support of the shrouds when placed in its mast step, therefore stabilizing the mast. When lifting the mast, raise it vertically and position the hands quite wide apart giving better leverage.

Use the following guides and instructions to successfully building a dinghy mast pdf a mast.

Tightening the shrouds beyond their supporting tension causes a bend building a dinghy mast pdf the middle of the mast known as mast bendwhile adjusting the forestay varies the amount of forward or backward slope known as mast rake. Different wind conditions dictate the different [ rake and bend ] settings. Use the following guide to obtain the correct rake. After stepping the mast, adjust the shrouds and forestay to get the correct rake position.

Mast rake with general-purpose dinghies is not critical, however with racing dinghies it needs to be set q to the correct measurement for top performance sailing. Building a dinghy mast pdf sailboat masts are easy to step, where the mast heel is building a dinghy mast pdf into its step prior to it being pulled into the upright position with the mast being held securely in the mast gate. Deck-stepped boat masts are not supported by a mast gate and therefore must be lifted vertically, before being located into the mast step therefore less stable until the rigging is secured.

The foot of the mainsail may fit into a groove along the top of the main boom or be only attached by the outhaul device at the end of the boom. The boom is a horizontal spar, comprising of aluminium or wood, attached by a gooseneck fitting to the aft side of the mast. On some vinghy this may be fixed in a position, or or have a sliding fitting which allows the boom to be adjusted up or.

The tack of the mainsail is held in position close to the einghy by a fitting on the gooseneck and the [ clew ] is secured to the cinghy outhaul device by either rope or shackle.

The clew outhaul enables the foot of the sail to be tensioned and is used to alter the shape of the sail. The sail foot is tensioned overall with a kicking strap, kicker or boom vang fitting, which attaches to the underside of the boom, a quarter distance from the mast, and to the building a dinghy mast pdf of the mast.

It comprises of a [ block and tackle ] which tensions the sail and cleated at the right tension. In addition, the mast is fitted with wire or rope halyards that are used to raise and lower the sails.

Designed to run inside the mast, they run through pulley block sheaves at the top of the mast and exit in a sheave box, being an alloy casting, that is incorporated the mast foot. The jib halyard sheave is positioned at the front of the mast below the forestay fitting, with the spinnaker halyard sheave above the forestay. The halyards are led down to small small swivel blocks buidling fixed rings.

The mainsail halyard sheave is often incorporated into the mast head fitting at the back of the mast inside the sail track. Older rigs have external halyards that run through pulley blocks at the appropriate position for main, jib and spinnaker. Asymmetric Spin. Types of Sailboat Rigging Before knowing how to rig a sailboat or dinghy, and understanding of the various sailboat rigging types is required: Single handed one-person sailing dinghies usually having a single sail, fitted onto an [ unstayed mast ] housed in a large tube or mast support at the front of the sailing dinghy.

Two-person sailing dinghies, have two or more sails, and a mast which is supported or stayed by three wires. Unstayed Sailboat Mast Type Boats that have unstayed masts are stored without their mast.

Keel Stepping Keel-stepped sailboat masts are easy to step, where the mast heel is positioned into its step prior to it being pulled into the upright position with the mast being held securely in pvf mast gate. Lay the keel stepped mast and rigging on the boat with the masthead to the stern of the boat.

Rest the mast heel on the mast step with the front side of the mast uppermost. The other person pulls on the forestay. The person supporting the mast guides it into the mast gate.

Tension the shrouds. Adjust the shrouds and forestay to get the desired mast rake and mast bend Make sure that the halyards are not twisted around the rigging. Deck Stepping Deck-stepped boat masts are not supported by a mast gate and therefore must be lifted vertically, before being located into the mast step therefore less stable until the rigging is secured.

Lay the deck stepped mast on the ground next to the sailing dinghy with the aft side uppermost and the mast head towards the bow. Attach the shrouds to the chainplates. Stand building a dinghy mast pdf mast vertically alongside the sailing dinghy.

Lift the mast in the vertical position until it can be stepped. Slot the mast into the recessed mast step fitting in the foredeck. Held by the shrouds, allow the mast to lean forwards. Attach the forestay to the ldf. Adjust the shrouds and forestay to get the desired mast rake and mast bend.

Masr the halyards are not twisted around the rigging. Sail Boom The foot of the mainsail may fit into a groove along the top of the main boom or be only attached by the outhaul device at the end of the boom.
