30-576: The MG 335 is a British sailboat , that was designed by Tony Castro and first built in 1986. The design is out of production. The boat was built by Northshore Yachts in the United Kingdom between 1986 and 1994. The MG 335 is a small recreational keelboat , built predominantly of glassfibre . It has a fractional sloop rig, an internally-mounted spade-type rudder and a fixed fin keel . It displaces 8,900 lb (4,037 kg) and carries 3,800 lb (1,724 kg) of ballast. The boat has

60-436: A crane and are typically stepped on the keel through any cabin or other superstructure. Many sailboats have an alternate means of propulsion, in case the wind dies or where close maneuvering under sail is impractical. The smallest boats may use a paddle ; bigger ones may have oars ; still others may employ an outboard motor , mounted on the transom; still others may have an inboard engine . Gaff sail Gaff rig

90-457: A draft of 6.25 ft (1.91 m) with the standard keel. The boat is fitted with a Volvo model 2002 diesel engine . The fuel tank holds 25 U.S. gallons (95 L; 21 imp gal) and the fresh water tank has a capacity of 55 U.S. gallons (210 L; 46 imp gal). The boat has a PHRF racing average handicap of 138 with a high of 138 and low of 138. It has a hull speed of 7.05 kn (13.06 km/h). The MG 335 design

120-516: A gaff rig has a shorter mast than a Bermudan rig . In short-ended craft with full body, heavy displacement and moderate ballast ratio, it is difficult to set enough sail area in the Bermudan rig without a mast of excessive height and a centre of effort (CE) too high for the limited stability of the hull . Because of its low aspect ratio , the gaff rig is less prone to stalling if oversheeted than something taller and narrower. Whilst reaching ,

150-463: A given hull design. A sail hoisted from a gaff is called a gaff-rigged (or, less commonly, gaff rigged or gaffrigged ) sail . Gaff rig remains the most popular fore-aft rig for schooner and barquentine mainsails and other course sails , and spanker sails on a square rigged vessel are always gaff rigged. On other rigs, particularly the sloop , ketch and yawl , gaff rigged sails were once common but have now been largely replaced by

180-407: A jib. Most modern designs have only one sail, the mainsail; however, the traditional catboat could carry multiple sails from the gaff rig. Catboat is a charming and distinctive sailboat featuring a single mast with a single large sail, known as a gaff-rigged sail, and a broad beam that ensures stability. This type of vessel, named after the "cat" tackle used in sailing, has a rich history dating back to

210-431: A lot of weight in two "wings" which run sideways from the main part of the keel. Even more recent is the concept of canting keels , designed to move the weight at the bottom of a sailboat to the upwind side, allowing the boat to carry more sails. A twin keel has the benefit of a shallower draft and can allow the boat to stand on dry land. Multihulls, on the other hand, have minimal need for such ballast, as they depend on

240-411: A reduced draft, with a much reduced underwater profile. This, in turn, results directly in reduced wetted surface area and drag. Without a ballast keel, multihulls can go in shallow waters where monohulls can not. There are trade-offs, however, in multihull design. A well designed ballasted boat can recover from a capsize, even from turning over completely. Righting a multihull that has gotten upside down

270-501: Is a sailing rig (configuration of sails, mast and stays) 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. The gaff enables a fore-and-aft sail to be four sided, rather than triangular. A gaff rig typically carries 25 percent more sail than an equivalent Bermuda rig for

300-399: Is another rig with a four-sided fore-aft sail . Unlike the gaff rig where the head hangs from a spar along its edge, this rig supports the leech of the sail by means of a spar named a sprit . The forward end of the sprit is attached to the mast but bisects the face of the sail, with the after end of the sprit attaching to the peak and/or the clew of the sail. For a given sail area

330-489: Is difficult in any case and impossible without help unless the boat is small or carries special equipment for the purpose. Multihulls often prove more difficult to tack, since the reduced weight leads directly to reduced momentum, causing multihulls to more quickly lose speed when headed into the wind. Also, structural integrity is much easier to achieve in a one piece monohull than in a two or three piece multihull whose connecting structure must be substantial and well connected to

360-461: Is easier for a short-handed crew to manage. A yawl is similar to a ketch, with a shorter mizzen mast carried astern the rudderpost more for balancing the helm than propulsion. Traditional sailboats are monohulls , but multi-hull catamarans and trimarans are gaining popularity. Monohull boats generally rely on ballast for stability and usually are displacement hulls. This stabilizing ballast can, in boats designed for racing, be as much as 50% of

390-436: Is similar to a sloop with a single mast and mainsail, but generally carries the mast further aft to allow for a jib and staysail to be attached to the head stay and inner forestay, respectively. Once a common racing configuration, today it gives versatility to cruising boats, especially in allowing a small staysail to be flown from the inner stay in high winds. A catboat has a single mast mounted far forward and does not carry

420-421: Is the sloop, which features one mast and two sails, typically a Bermuda rigged main , and a headsail . This simple configuration is very efficient for sailing into the wind. A fractional rigged sloop has its forestay attached at a point below the top of the mast, allowing the mainsail to be flattened to improve performance by raking the upper part of the mast aft by tensioning the backstay. A smaller headsail

450-469: Is what prevents leeway and allows sailing towards the wind. This can be an external piece or a part of the hull. Most monohulls larger than a dinghy require built-in ballast . Depending on the design of the boat, ballast may be 20 to 50 percent of the displacement. The ballast is often integrated into their keels as large masses of lead or cast iron. This secures the ballast and gets it as low as possible to improve its effectiveness. External keels are cast in

480-457: The Bermuda rig sail, which, in addition to being simpler than the gaff rig, usually allows vessels to sail closer to the direction from which the wind is blowing (i.e. "closer to the wind"). The gaff is hoisted by two halyards : Additionally, a gaff vang may be fitted. It is a line attached to the end of the gaff which prevents the gaff from sagging downwind. Gaff vangs are difficult to rig on

510-488: The aft -most sail, so are typically only found on schooners or ketches, and then only on the foresail or mainsail. A triangular fore-and-aft sail called a jib-headed topsail may be carried between the gaff and the mast . Gunter-rigged boats are similar, smaller vessels on which a spar (commonly, but incorrectly called the gaff) is raised until it is nearly vertical, parallel to the mast and close adjacent to it. Topsails are never carried on gunter rigs. The spritsail

540-545: The 19th century in the coastal regions of the United States, particularly New England, where it was widely used by fishermen and sailors. With its straightforward design and uncomplicated rigging, the catboat offers a straightforward and laid-back sailing experience, making it an ideal choice for beginners and pleasure sailors alike. Even today, catboats continue to be cherished by enthusiasts who appreciate their heritage and enjoy their picturesque appearance while cruising through

570-444: The CE being set further back, will encourage a small craft to bear up into the wind, i.e. strong weather helm . The boat builder can compensate for this at design stage, e.g. by shifting the keel slightly aft, or having two jibs to counter the effect. The gaff-cutter is in fact a very popular sailplan for small craft. The helmsman can reduce weather helm significantly, simply by sheeting out

600-481: The bottom end in a receptacle that is supported above the keel of the boat or on the deck or other superstructure that allows the mast to be raised at a hinge point until it is erect. Some masts are supported solely at the keel and laterally at the deck and are called "unstayed". Most masts rely in part or entirely (for those stepped on the deck) on standing rigging , supporting them side-to-side and fore-and aft to hold them up. Masts over 25 feet (7.6 m) may require

630-532: The geometry of their design, the wide base of their multiple hulls, for their stability. Designers of performance multihulls, such as the Open 60's , go to great lengths to reduce overall boat weight as much as possible. This leads some to comment that designing a multihull is similar to designing an aircraft. A centreboard or daggerboard is retractable lightweight keel which can be pulled up in shallow water. On small sailboats, masts may be "stepped" (put in place) with

660-470: The hull itself has sufficient buoyancy to remain afloat. A multihull optimized for light weight (at the expense of cruising amenities and storage for food and other supplies), combined with the absence of ballast can result in performance gains in terms of acceleration, top speed, and manoeuvrability. The lack of ballast makes it much easier to get a lightweight multihull on plane, reducing its wetted surface area and thus its drag. Reduced overall weight means

690-450: The hulls. All these hull types may also be manufactured as, or outfitted with, hydrofoils . All vessels have a keel , it is the backbone of the hull. In traditional construction, it is the structure upon which all else depends. Modern monocoque designs include a virtual keel. Even multihulls have keels. On a sailboat, the word "keel" is also used to refer to the area that is added to the hull to improve its lateral plane. The lateral plane

720-573: The mainmast, but forward of the rudder post. The second mast is called the mizzen mast and the sail is called the mizzen sail. A ketch can also be Cutter-rigged with two head sails. A schooner has a mainmast taller than its foremast , distinguishing it from a ketch or a yawl. A schooner can have more than two masts, with the foremast always lower than the foremost main. Traditional topsail schooners have topmasts allowing triangular topsails sails to be flown above their gaff sails ; many modern schooners are Bermuda rigged. The most common modern sailboat

750-403: The mainsail. Sheeting out may appear to create an inefficient belly in the sail, but it is often a pragmatic alternative to having a heavy helm. A swing keel lifted halfway is the perfect treatment for weather helm on a gaffer. The usual adjustments to mast rake, or even bowsprit length may be made to a gaffer with persistent heavy weather (or lee) helm. On a gaff-rigged vessel, any heading where

780-399: The shape of the keel. A monohull's keel is made effective by a combination of weight, depth, and length. Most modern monohull boats have fin keels, which are heavy and deep, but short in relation to the hull length. More traditional yachts carried a full keel which is generally half or more of the length of the boat. A recent feature is a winged keel , which is short and shallow, but carries

810-399: The waterways. A dinghy is a type of small open sailboat commonly used for recreation, sail training , and tending a larger vessel. They are popular in youth sailing programs for their short LOA , simple operation and minimal maintenance. They have three (or fewer) sails : the mainsail , jib , and spinnaker . Ketches are similar to a sloop, but there is a second shorter mast astern of

840-720: The weight of the boat, but is generally around 30%. It creates two problems; one, it gives the monohull tremendous inertia, making it less maneuverable and reducing its acceleration. Secondly, unless it has been built with buoyant foam or air tanks, if a monohull fills with water, it will sink. Multihulls rely on the geometry and the broad stance of their multiple hulls for their stability, eschewing any form of ballast. Some multihulls are designed to be as light-weight as possible while still maintaining structural integrity. They can be built with foam-filled flotation chambers and some modern trimarans are rated as unsinkable, meaning that, should every crew compartment be completely filled with water,

870-437: The wind is within 20 degrees of dead aft is considered a run . When running with a gaff rig, the CE of the mainsail may actually be overboard of the hull, in a stiff wind the craft may want to broach . Running goose winged with a balloon staysail poled out to windward will balance the CE; Nick Skeates circumnavigated Wylo II with this configuration. In light winds, or when racing, a watersail may also be set. Since 1972,

900-753: Was developed into the CS 34 in 1989, also designed by Castro and built by CS Yachts in Canada . The CS 34 differs in that it has a taller mast with a masthead rig and higher displacement than the MG 335.
