The development of the rig is thought to have begun with fore-and-aft rigged boats built by a Dutch-born Bermudian in the 17th Century. The Dutch were influenced by Moorish lateen rigs introduced during Spain's rule of their country. The Dutch eventually modified the design by omitting the masts, with the yard arms of the lateens being stepped in thwarts. By this process, the yards became raked masts. Lateen sails mounted this way were known as leg-of-mutton sails in English. The Dutch called a vessel rigged in this manner a bezaan jacht. A bezaan jacht is visible in a painting of King Charles II arriving in Rotterdam in 1660. After sailing on such a vessel, Charles was so impressed that his eventual successor, The Prince of Orange presented him with a copy of his own, which Charles named Bezaan The bezaan rig had been introduced to Bermuda some decades before this. Captain John Smith reported that Captain Nathaniel Butler, who was the governor of Bermuda from 1619 to 1622, employed a the Dutch boat builder, one of the crew of a Dutch frigate which had been wrecked on Bermuda, who quickly established a leading position among Bermuda's boat makers (to the resentment of many of his competitors, who were forced to emulate his designs). A poem published by John H. Hardie in 1671 described Bermuda's boats such: With tripple corner'd Sayls they always float, About the Islands, in the world there are, None in all points that may with them compare.
Ships of somewhat similar design were in fact recorded in Holland during the 17th Century. The rig was eventually adopted almost universally on small sailing craft in the 20th Century, although as seen on most modern vessels it is very much less extreme than on traditional Bermudian designs, with lower, vertical masts, shorter booms, omitted bowsprits, and much less area of canvas.
The Bermuda sloop became the predominant type of sailing vessel both in the Bermudian colony and amongst sloop rigs worldwide as Bermudian traders visited foreign nations. Soon, shipbuilding became one of the primary trades on the island and ships were exported throughout the English colonies on the American seaboard, and in the West Indies, and eventually to Europe. Bermudians built roughly a thousand ships during the 18th Century. Although many of these were sold abroad, the colony maintained its own large merchant fleet, which, thanks as partly to the domination of trade in many American seaboard ports by branches of wealthy Bermudian families, and partly to the suitability and availability of Bermudian vessels, carried much of the produce exported from the American south to Bermuda and to the West Indies. Bermuda sloop design strongly influenced the development of vessels built by the Chesapeake builders, and Bermudian features like the raked mast began to appear in American schooners.
The Bermuda sloop differed from other sloops partly in the form of its hull, which was very stiff. This stiffness was a result partially of the shipbuilding skills on the islanders, but also thanks to the availability of large quantities of Bermuda cedar, which has superior qualities of rot-resistance, low density (making the ships lighter and faster) and high strength (making the ships more durable). Designed to sail primarily on the open ocean, their relatively deep hulls gave them superior seaworthiness by comparison to similar vessels, such as the Baltimore clipper, which were intended to operate in coastal waters. Despite this, single-masted Bermudian sloops were optimised for speed, and were very demanding craft to sail. In rough weather, they were easily swamped. The vessels carried little fixed ballast, allowing for the carriage of large cargoes.
During wartime, much of Bermuda's merchant fleet turned to privateering, a lucrative activity to which the fast sloops were well-endowed. They often carried sufficient crew out to return with several prizes, and these extra crew were useful both as movable ballast, and in handling the labour-intensive sloops. The threat of piracy and privateering was a large problem for mariners of all nations during the 17th and 18th centuries, but it was also as widely popular an enterprise. Bermudian mariners excelled at the activity, thanks largely to the speed, especially to windward, and maneouverability of the Bermuda sloops, which suited them well to the role. The same abilities allowed Bermuda sloops to escape from better-armed privateers - and, even more so, to escape from larger men-of-war, which, with their square rigs, could not sail as closely to windward. The ability of the sloop rig in general to sail upwind meant a Bermuda sloop could outrun most other sailing ships by simply turning upwind and leaving its pursuers foundering in its wake. This evasiveness meant they were highly prized amongst merchantmen. Of course, these qualities also made Bermuda sloops the ship of choice for the pirates themselves, earlier in the 18th Century, as well as for smugglers.
The American War of 1812 was to be the encore of Bermudian privateering, which had died out after the 1790s, due partly to the build up of the naval base in Bermuda, which reduced the Admiralty's reliance on privateers in the western Atlantic, and partly to successful American legal suits, and claims for damages pressed against British privateers, a large portion of which were aimed squarely at the Bermudians. During the course of the American War of 1812, Bermudian privateers were to capture 298 ships (the total captures by all British naval and privateering vessels between the Great Lakes and the West Indies was 1,593 vessels).
The characteristics of the Bermudian vessels were such that, when the Royal Navy began building up its establishment in Bermuda, following US independence, it commissioned large numbers of these vessels from Bermudian builders, and bought many more up from trade. As the long-boomed, single-masted designs were such demanding sailers, the navy favoured multiple-masted designs, which also had the advantage of longer decks, which carried more guns. Although, today, these vessels might be considered schooners, and some might debate the use of the term sloop for multiple-masted vessels, the Royal Navy rated such vessels as sloops-of-war. The first three built, HMS Dasher, HMS Driver, and HMS Hunter, were each of 200 tons, well-armed, with twelve 24 pounders (Note: this contention must be challenged, while the ships would carry 12 guns, there is little likelihood they might carry 24 pounders: the armament of enormous ships of the line. Even a 36 gun frigate, a much larger ship than a Bermudian, carried only 18 pounders and long 9's. I suspect the author here is referring to carronades. If a Bermuda sloop were armed with long guns, they were at best 6 pounders and possibly 4's). They were intended to counter the then-extant menace of French privateers, which the Navy's ships-of-the-line were ill-designed to counter Eventually, Bermuda sloops became the standard advice vessels of the navy, used for communications, reconnoitring, anti-slaving, and anti-smuggling, and other roles to which they were well suited. The most notable examples of these were HMS Pickle, which raced back to England with news of the British victory and the death of Admiral Lord Nelson at the end of the Battle of Trafalgar (it had also been Bermudian picket boats which had given warning of the enemy fleet), and HMS Whiting, of 79 tons and four guns, which lowered anchor in the harbour of Hampton Roads on 8 July, 1812. She was carrying despatches from Portsmouth, and, while her captain was being rowed ashore, the American privateer Dash, which happened to be leaving port, seized the vessel. The crew of the Whiting had not yet received news of the American declaration of war, and her capture was the first naval action of the American War of 1812.
Many of the shipwrights who helped to develop shipbuilding in the American south, especially on the Virginia shore of the Chesapeake (Bermuda, also known as Virgineola, had once been part of Virginia, and had maintained close connections ever since), were Bermudian slaves, and the design and success of the area's schooners owes something to them, also
Although the term Bermuda sloop is applied to refer specifically to the type of small sailing ships discussed above, the term also was used to describe the small working boats used for moving freight about Bermuda's islands, for fishing, and other coastal activities. Motor vehicles were banned in Bermuda until after the Second World War, and the roads were few and poor until the requirements of that war advanced their development. Boats, as a consequence, remained the primary method of moving people and materials around Bermuda well into the 20th Century. The Bermuda rig had begun its development in such small boats in the 17th Century, before being adapted to ships, and by the 19th Century the working boats of the island conformed to an almost pure design, with high, raked masts, long bowsprits, and vast areas of sail. They were, in appearance, scale models of the sea-going sloops. Although such small sloops are rare, today (the one pictured at right is a 19th Century survivor), the design was scaled down to produce the Bermuda Fitted Dinghy, a class of racing vessel used in traditional competition between Bermudian yacht clubs. The term Bermuda sloop has come to be used outside of Bermuda, today, to describe any single masted, Bermuda rigged boat, also known as Marconi sloops, although most are far less extreme in their design than was once the norm in Bermuda, with bowsprits omitted, masts vertical and shortened, and booms similarly shortened. Spinnaker booms and multiple jibs are rarely seen. The reduced sail area makes modern boats much more manageable, especially for small or inexperienced crews.
