History

The xebec owes much of its design to the earlier galleys and galleasses of the Mediterranean. The root of the name probably comes from an Arabic word for 'small ship', and is rendered into English in three forms: 'xebec', 'chebec', and 'zebec', though the word exists in many other languages as well, indicating its popularity (or at least knowledge of its existence) in the rest of Europe.

These ships had long narrow hulls, and were fitted with oars like their galley predecessors. They were intended to be fast and maneuverable, whether under oar-power or under sail.

17th and 18th century Christian shipping in the Mediterranean was threatened by the Barbary corsairs, who were Muslim pirates based in Northern Africa. The vessel of choice for these pirates in the early days was the galley, whose oars allowed them to overtake merchant vessels caught in light wind. But as time wore on, the trading nations responded to the threat by deploying warships to tackle the corsair problem. Galleys were swift and carried many men, but were not designed to stand up to the broadsides of modern warships.

In response, the Barbary Corsairs evolved their galleys into a new design that would stay competitive with the warships sent against them. In order to mount broadside guns, they widened the hull for extra deck-room and stability, and they removed many or all of the rowers to make room for broadside guns. These changes shifted the motive power of the vessel away from oar-power and onto the three huge lateen sails. And thus, the graceful and distinctive form of the xebec was born.

Their foremasts are typically raked forward, while the main and mizzen were either straight or raked slightly back. The massive lateen yards were so large that they were frequently composed of two spars lashed together -- more like masts than typical yards. Most xebecs did not have a bowsprit, but their beakheads frequently featured a long prow.

A few of the western nations tried square sails on the xebec's mainmast and sometimes even the mizzenmast. The square-rigged mainmast would have topsails and even topgallants, and the mizzen would have a square topsail (while still maintaining the lateen lower-sail). A xebec rigged this way was known as a Polacre-Xebec.

Commonly, though, the standard lateen rig for xebecs had a single triangular sail on each mast, and had none of a square rig's topsails or topgallants. The lateen rig offered many advantages over the square rig, the most significant of which was the ability to pinch far closer to the wind than square sails could. This meant they could both quickly catch up to and quickly flee from square-rigged vessels when sailing close to the wind.

The corsairs favored the xebec for its speed and maneuverability, and for its shallow draft which also aided in escaping larger vessels. These qualities were recognized by many of the European navies, and the vessel was quickly adopted into the Mediterranean squadrons as commerce-raiders and anti-piracy cruisers. As warships, xebecs mounted as many as 36 guns on their topdeck. Depending on the weight of the guns, this made them competitive with naval sloops of war, and even with some of the frigates of the day.

The xebec under sail was a beautiful sight, and it is said that the design was one of the fastest and most agile in the Mediterranean. Some of the same qualities that made it so successful in light seas also made it unsuitable for rough weather. The low freeboard and the shallow draught made the vessel vulnerable to swamping, and it would roll heavily on anything more than moderate waves. Thus, the advantages that the xebec has inland make it a poor choice for open-ocean sailing.

Xebecs were also lightly-built vessels. Unlike the massive, bulky timbers of ships of the line, xebecs were delicate and graceful. They were gazelles, not war-horses. Their tactics in battle reflected this. Xebec captains were loath to engage a foe of equal armament in a gun-battle. Instead, they relied upon their speed, maneuverability, and sweeps to pick their battles, and deposit large numbers of boarders on the decks of their enemies.

The xebec's qualities of speed and shallow draught, and the ability to sail extremely close to the wind, are highly prized by traders as well -- particularly those engaged in the coastal trade and its close cousin, smuggling. While it requires a somewhat larger crew, and has a smaller cargo capacity than other vessels of similar size, its sailing characteristics and combat ability make it an excellent choice for those interested in a swift and powerful coastal vessel.

Historically, the xebec was not well-represented in the Caribbean. It wouldn't have easily made the crossing from Europe, for one thing. A xebec captain risked outright sinking in rough seas and bad weather, far from the somewhat calmer waters of the Mediterranean that the ship was designed for. But the Caribbean shipbuilding industry was quite active and versatile, and the xebec is a ship design so striking and so interesting that we couldn't resist making it available as a locally built version.

Strategy and Use

In Pirates of the Burning Sea, we expect a variety of players to sail the xebec. It will turn up as an available ship for naval officers of low rank, roughly on par with the sloop-of-war, though it is not of course one of the rated ships. Merchants and free traders can buy the xebec from civilian shipyards, probably for making numerous short-haul runs within a particular island chain. And pirates, of course, should get great use from this swift, sharp hawk of the seas.

Tactics

The xebec was the favored vessel of the Barbary pirates of the northern coast of Africa. Indeed, it seems to be a ship designed with the hunter's needs in mind. Its draft allowed it to hide in shallow coves, and escape from heavier pursuers over reefs and shoals. Its huge lateen sails gave it great speed very close to the wind -- another useful trick when evading the square-rigged ships of the western fleets. Although cramped, the deck of even a medium-sized xebec could mount up to 14 cannon, and could accommodate over 100 sailors. Even the huge lateen yards were useful during boarding where they could be dropped onto the victim's deck, creating a makeshift bridge for the boarders to clamber across.

As swift and ferocious as these vessels are, xebec captains must be constantly aware of their many limitations. The same sails that give them such an advantage while sailing are extremely vulnerable to dismantling fire. It only takes losing three yards to leave a xebec dead in the water. In addition, xebec hulls are light and sleek, and they don't hold up well under heavy fire. Even their shallow draft has a downside, as they sail poorly in rough weather and high seas.

Xebec captains are specialists. They have given up the versatility of sloops and schooners for the deadly efficiency of a vessel designed for the hunt. Realizing their inherent limitations, they avoid confrontations with larger forces, and the shattering broadsides that are so devastating to their light vessels. Like predators in the wild, they prey on the slow and weak: lunging in for the kill and overwhelming the opposing crew with their numbers, then quickly withdrawing before their retreat is cut off.

Xebecs were sometimes employed as light warships in the national navies, often to combat these pirates and privateers who also found the vessel so appealing. And in fact, the same sailing characteristics that make xebecs so suited for the hunt are also appealing to coastal traders who value speed and draft over cargo capacity.

Freetraders will find that while the cargo capacity is small, the 'Corsair' Xebec is a superior vessel of fighting, boarding, and fleeing enemy vessels. The close-haul sailing speed, freetrader bonuses, and square-rig design of a majority of other ships means that what the 'Corsair' can't out-run, it can out-fight. With various hull armor, sail, and gun outfittings, the stock 'Corsair' Xebec can be brought to mastercraft levels for little cost.

Variants

Other variants of the Corsair:

Comparable Ships

The most comparable ship in Pirates of the Burning Sea is the light sloop-of-war, a three-masted, square-rigged vessel. These were the smallest "ships" in the navies, ranked below the frigates of the 6th rate but larger than brigs of war. These vessels were of comparable size and armament to the xebec, though the rig was significantly and obviously different, and the sloop-of-war is a more robust vessel both in combat and in rough seas. However, in sailing respects, most vessels of comparable performance are half its level, thus severely out-gunned.

Distinguishing Characteristics

  • Extremely shallow draft.
  • Fares poorly in heavy seas.
  • Lateen sails allow the xebec to pinch closer to the wind than square-rigged vessels.
  • Light framing makes the hull more gracile, and also more fragile than the more stout oak hulls of traditional western vessels.
  • It lacks a true bowsprit, but has a long prow.
  • No shrouds, so working with the higher rigging - though uncommon - is difficult.
