Sloop

January 22, 2011 by staff 

Sloop, A sloop (Sloep of Dutch) is a sailing vessel with fore and aft rigs and a single mast further forward than the mast of a cutter. A preliminary sloop triangle is smaller than a knife, unlike a cup; a sloop usually bends only one headsail, though this distinction is not definitive, as some sloops of Sloop friendship have more than one. Ultimately the position of the mast is the most important factor in determining whether a ship is classified as a sloop. [Citation needed]

On a gaff, one boat masts, the clearest distinction between a sloop and a cutter along the forestay. The sloop, he runs to the outer end of the bowsprit, which means that the bowsprit must remain in position and cannot be retracted. On a cut, the short stay at the head of the stem of the hull. This allows the bowsprit to run back toward the inside and tidy. This can be useful in congested ports or when stowing the jib in strong wind

No design is perfect for all conditions; sloops are designed to optimize upwind sailing. However, sloops also offer an excellent overall compromise acceptable if it is not optimal at all points of sail. It is clear that management’s most difficult sailing into the wind (known as sailing close-hauled), which requires some specific design features. The sail must be as vertical as possible to maximize the power of wind.

Two forces acting on a ship to push it vertically (also known as heel over): (1) the weight of the platform itself will tend to heel the boat, and (2) the lateral force of wind on sails. The sloop is a platform of light with fewer lines and spars; sails on a sloop tend to be flat which minimizes the side force when it is well stocked. The tipping forces are counterbalanced by the keel, which uses weight and hydrodynamic forces to compensate for the rigging and sails.

When sailing upwind, it is also important to minimize the drag of wind on the sail and rigging. A major cause of the drag of the sail is a vortex of turbulent air generated by the top of the mast and sail. Secondary causes are non-optimal aerodynamic shapes of masts, stays and control lines. The sloop minimizes the drag of the tip vortex with a design of sails high and narrow (high aspect), maximizing the amount of sail for a tip vortex given relative to a square-rigged or gaff-rigged ship. In addition, the simplicity of the platform reduces the induced drag by control lines, masts and spars.

The modern yachting sloop is known as the Bermuda sloop, because of its platform in Bermuda (also known as Marconi rig, because of its resemblance to the towers wireless by Guglielmo Marconi), which is the flat -optimal shape for the sail to the wind, consequently sloops are popular with boaters and marine sports, and racing. The rig is simple in its basic form, but when set correctly, it is handy and fast. The main drawback is the relatively large size of the sails, especially on large vessels. It is also less successful sailing downwind, the addition of a spinnaker is a need for faster speed downwind, but in all the strongest winds, and the spinnaker is a sail inherently unstable and requires constant trimming.
