In sailing, a snow, snaw or snauw is a square-rigged vessel with two masts, complemented by a snow- or trysail-mast stepped immediately abaft (behind) the main mast. [1]
The word 'snow' comes from 'snauw', which is an old Dutch word for beak, a reference to the characteristic sharp bow of the vessel. [1] The snow evolved from the (three-masted) ship: the mizzen mast of a ship was gradually moved closer towards the mainmast, until the mizzen mast was no longer a separate mast, but was instead made fast at the main mast top. As such, in the 17th century the snow used to be sometimes classified as a three-masted vessel. [2]
The snow dates back to the late 17th century and originally had a loose-footed gaff sail; the boom was introduced somewhere in the 18th century. It was a popular type of vessel in the Baltic Sea and was employed by a large number of nations during its time. The snow was considered a handy and fast sailing vessel, typically the largest two-masted vessel around, and was employed in both navy and merchant service. [3] When used as a naval vessel, snows were, in the early 18th century, typically fitted with 5 to 16 guns. Naval snows were mostly used for coastal patrols and privateering whereas in the merchant service snows traded all the way to the Mediterranean and sometimes even sailed as far as the West Indies.
Snow: the largest of all old two-masted vessels. The sails and rigging on the main mast of a snow are exactly similar to those on the same masts in a full-rigged ship; only that there is a small mast behind the mainmast of the former, which carries a sail nearly resembling the mizzen of a ship.
While the snow and the brig might appear closely related, this is in fact not the case. The two rigs developed from different directions, the brig evolving from the generally smaller brigantine, and the much older snow evolving from the larger three-masted ship. [1]
The most visible difference between the brig and the snow is the latter's "snow-mast", stepped directly behind the main mast. [5] In contrast to the brig, where the gaff and boom attach directly to the main mast, a snow's gaff, and in later times, its boom, were attached to the snow-mast. The use of this characteristic snow-mast offered several advantages over attaching the gaff directly to the main mast. [6]
The yoke (or jaw) of the gaff and the lacing of the gaff sail on a snow could move freely on the snow mast, unhindered by the iron bands that held together the (main) mast, nor limited by the main yard. The gaff on the snow mast could be raised higher than the main yard and independently of it. The resulting freedom allowed a snow, in contrast to a brig, to fly a main course without complications, as they typically did. [7]
However, in the late 18th century, brigs started to set main courses as well, which gave rise to the term snow-brig. The differences lessened even further when the snow-mast was replaced by a steel cable, at which point the term "snow-brig" gradually became interchangeable with the term "brig" and the term "snow" fell in disuse.
The twin brigs Lawrence and Niagara, American warships which participated in the Battle of Lake Erie in 1813, were both snow-brigs.
A schooner is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a topgallant. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner.
A sailing vessel's rig is its arrangement of masts, sails and rigging. Examples include a schooner rig, cutter rig, junk rig, etc. A rig may be broadly categorized as "fore-and-aft", "square", or a combination of both. Within the fore-and-aft category there is a variety of triangular and quadrilateral sail shapes. Spars or battens may be used to help shape a given kind of sail. Each rig may be described with a sail plan—formally, a drawing of a vessel, viewed from the side.
A brigantine is a two-masted sailing vessel with a fully square-rigged foremast and at least two sails on the main mast: a square topsail and a gaff sail mainsail. The main mast is the second and taller of the two masts.
A brig is a type of sailing vessel defined by its rig: two masts which are both square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships.
The bilander, also spelled billander or bélandre is a two-masted vessel, the foremast carrying square rigs on all of its yards and its taller mainmast having a long lateen mainsail yard with corresponding trapezoidal sail and rig inclined at about 45° with square rigs on the yards above that, the lowermost secured at the corners by a crossjack.
A barque, barc, or bark is a type of sailing vessel with three or more masts and mainmasts rigged square and only the mizzen rigged fore and aft. Sometimes, the mizzen is only partly fore-and-aft rigged, bearing a square-rigged sail above.
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.
A topsail ("tops'l") is a sail set above another sail; on square-rigged vessels further sails may be set above topsails.
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
A mainsail is a sail rigged on the main mast of a sailing vessel.
A barquentine or schooner barque is a sailing vessel with three or more masts; with a square rigged foremast and fore-and-aft rigged main, mizzen and any other masts.
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, 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.
A full-rigged ship or fully rigged ship is a sailing vessel with a sail plan of three or more masts, all of them square-rigged. Such a vessel is said to have a ship rig or be ship-rigged, with each mast stepped in three segments: lower, top, and topgallant.
A Thames sailing barge is a type of commercial sailing boat once common on the River Thames in London. The flat-bottomed barges, with a shallow draught and leeboards, were perfectly adapted to the Thames Estuary, with its shallow waters and narrow tributary rivers. The larger barges were seaworthy vessels, and were the largest sailing vessel to be handled by just two men. The average size was about 120 tons and they carried 4,200 square feet (390 m2) of canvas sail in six working sails. The mainsail was loose-footed and set up with a sprit, and was brailed to the mast when not needed. It is sheeted to a horse, as is the foresail; they require no attention when tacking. The foresail is often held back by the mate to help the vessel come about more swiftly.
A trysail is a small triangular or gaff rigged sail hoisted in place of a larger mainsail when winds are very high. The trysail provides enough thrust to maintain control of the ship, e.g. to avoid ship damage, and to keep the bow to the wind. It is hoisted abaft the mainmast or, on a brig, abaft the foremast. A trysail is analogous to a storm jib.
A polacca is a type of seventeenth- to nineteenth-century sailing vessel, similar to the xebec. The name is the feminine of "Polish" in the Italian language. The polacca was frequently seen in the Mediterranean. It had two or three single-pole masts, the three-masted vessels often with a lateen hoisted on the foremast and a gaff or lateen on the mizzen mast. The mainmast was square-rigged after the European style. Special polaccas were used by Murat Reis, whose ships had lateen sails in front and fore-and-aft rig behind.
A jackass-barque, sometimes spelled jackass bark, is a sailing ship with three masts, of which the foremast is square-rigged and the main is partially square-rigged and partially fore-and-aft rigged (course). The mizzen mast is fore-and-aft rigged.
Amazing Grace is an 83' topsail schooner. Its home port is in San Juan, Puerto Rico. The ship serves as the platform for the non-profit Maritime Leadership and is also available for private charters and memorials at sea. Maritime Leadership provides traditional sail training adventures through sailings ranging from 3–48 hours.
A sail plan is a drawing of a sailing craft, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. By extension, "sail plan" describes the arrangement of sails on a craft. A sailing craft may be waterborne, an iceboat, or a sail-powered land vehicle.
