Pirate haven:
A pirate ship had to have a base, a place where supplies could be bought, a ship could be repaired, booty could be sold, information could be gathered and the crew could rest and relax between missions.
Many coastal towns and many islands have been havens for pirates. The inhabitants might or might not engage in piracy themselves, but pirates were their customers.
In a pirate haven, pirates could purchase the kind of food needed aboard ship. Dried foods that would keep during an ocean voyage were essential. A staple was ship's biscuit or hard tack. Ship's biscuit was simply bread baked two or three times so that it had a hard crust and would keep for a long time. The bread was so hard that it could not be chewed until it was softened in water. Dried meat and dried vegetables were also common pirate rations.
Water was essential aboard ship. However, the water was stored in wooden barrels and would turn green with algae in time. Officers preferred wine, while the crew mainly drank beer.
A pirate needed gunpowder to use in cannon and also in the flintlock pistols they often carried.
Wooden sailing ships had to be repaired frequently. One of the problems leading to frequent repair is the shipworm (Teredo navalis).
A shipworm is a marine bivalve highly specialized for boring into wood. The shell is greatly reduced and modified into a rasp for grinding into wood. The shipworm has a long worm-like body that is protected by the wood into which it is boring. Teredo can only invade new wood when they are in the larval stage and during the short larval period when they are free swimming. An initial entrance hole in a plank may be so tiny it can't be seen. The first hint of problems comes after the interior of the plank is nearly destroyed and the wood disintegrates.
In the era of wooden-hulled ships, the danger of a ship literally sinking under the crew was very real. Quite often a ship's crew had to abandon or rebuild their ship because it was 'rotten' from the holes bored in its bottom by shipworms.
The man who could repair a ship was a ship's carpenter. A pirate ship would not normally carry a ship's carpenter, because he would have demanded a share of the loot despite not being a fighting man. Thus, a pirate ship would normally be repaired in a pirate have by a shore based ship's carpenter.
In addition to carpentry services, a pirate ship had to be regularly resupplied with rope for ship's lines, canvas sails, blocks, tackle, etc.
The booty from a successful pirate attack had to be sold. A pirate might sell some of the very valuable loot himself. However, it was normally more efficient to use a pirate haven based middleman. The middleman had a strong, well defended warehouse and, usually a front business to account for how he acquired the pirate booty.
A pirate was interested in high-value, easily transported booty or loot. A ship loaded with corn was not a really good pirate target. The ship full of corn would have had to be sailed to a pirate haven and a buyer found for the corn. A ship carrying gold or jewels was a prime pirate target.
In order to select a profitable target, it was convenient for a pirate to have spies in normal ports. A spy would determine that a high value cargo was due to be shipped and then he could notify a pirate of the prize, in return for payment.
Even after a high-value target had been identified, there was the problem of actually finding the ship. Of course, the oceans are vast and it would be very hard to locate a ship at random on the ocean. However, much of the world's shipping is done in fairly restricted shipping lanes. The shipping lanes usually have favorable winds and currents. The shipping lanes also avoid hidden rocks and reefs. Even though most ships used the shipping lanes, it was not easy to find a lone ship at sea.
A pirate ship did not spend all of its time at sea. When it was in a pirate haven, the pirate crew could drink and carouse in waterfront taverns. Of course, a pirate haven would have women available for the pirates. However, history records that many of the pirates maintained homosexual relationships instead of or in addition to their relations with women.
Ships:
Oared Ships:
The first ships that were really warships were galleys. Galleys are large seagoing vessels propelled primarily by oars in battle and equipped with sails for cruising. Galleys were narrow ships built for speed and normally carrying a ram.
The Egyptians, Greeks, Phoenicians, Byzantines, Arabs, and other ancient peoples all used galleys for both war and trade. However, galleys came to be known as warships. The galley was the standard European battle vessel until the late 16th century, when the sail-powered and more heavily armed galleon began to replace it.
The early Greek galley possessed a single mast with a broad rectangular sail that could be furled. The mast was stowed or lowered when rowing into the wind or in battle. The Greek galley was a true seagoing warship. It typically possessed a bronze-shod ram.
In the 8th century BC, the bireme was created. Descendant from the galley, it was about 25m (80') long, with a maximum beam of about 10'. The bireme had 2 banks of oars - hence its name. The Phoenician bireme had a single pole mast with a square sail and steering oars to port and starboard, with two banks of oars
By the 6th century BC triremes were in use. The trireme had 3 banks of oars, and a full spar deck instead of the center-line gangway of the early bireme. By the 5th century the triremes measured a length of 40 m (125'), a beam of 6 m (20') and a draft of 1 m (3'). They were manned by 200 officers, seamen, and oarsmen (about 85 per side), with a small band of heavily armed marines. The trireme could reach 7 knots under oars.
The various galleys, biremes and triremes were basically warships. They could carry cargo, but were not very efficient as cargo haulers. Probably their major use as cargo haulers was in waters made dangerous by pirates or other warships.
Galleys would not make good pirate ships. The cost of feeding many rowers would make the use of a galley impractical. Also, the oars would make boarding another ship nearly impossible.
Galleys were not really ocean going ships. They were long and narrow and not too stable. They were mainly used to move from port to port, hugging the coast.
A galley could use its square sail to be pushed by the wind. However, sailing into the wind was impossible,
Caravel:
The caravel was a small two-decked sailing ship developed by Portuguese fishermen. It was used widely during the 15th century by maritime nations of the Mediterranean. Many of the fleets dispatched to explore the New World sailed with a large complement of caravels. It was used by 15th- and 16th-century explorers, including Magellan and Columbus. Two of Christopher Columbus' ships, the Nina and the Pinta, were caravels.
The squat, 3-masted caravel was slower than the galley, but designed to sail into the wind. It offered more space for cargo, and more spacious living quarters in long voyages. Initially lateen rigged - triangular fore-and-aft sails set on a long, sloping yardarm - on two masts, the caravel soon sported three masts - foremast, mainmast, and mizzenmast - with square sails on the forward two and a lateen sail on the third. The lateen sail enabled a ship to take advantage of a wind from the side of the vessel.
The caravel, which replaced the oared galley, was itself later replaced for long voyages by the heavier, deeper-draft Carrack.
