Ship Types

There are two classifications of ships: sailing ships and oar-driven vessels.

Sailing ships are classed according to how easily they can be handled and how quickly the ship responds to the helm. This is their “yare.” There are five types of ship, ranging from yare A to yare E. Light ships with lateen sails are more likely to be classed as yare A, whereas very heavy square-sailed ships are likely to be classed as yare E. This is not always the case, as draft, beam to length ratio and the number of masts can make ships more or less yare.

Oar-driven ships are classed according to their purpose, and described as ramships, merchant ships and barges. These are further classed as “heavy” or “light.” Heavy ships reflect yare D & E vessels with respect to drifting. Light ships reflect yare C vessels. Some oar-driven vessels can be sailed.

The following ships are available for purchase and use in my game world; the list is subject to expansion at a later date.

Barge: river vessels of varying sizes designed to haul goods up and down stream.
Bireme: light galley designed for battle, beached at night.
Caravel: ocean-going, manoeuvrable 2-masted sailing ship.
Carrack: heavy ocean-going trade ship designed for long voyages.
Coaster: light coastal vessel based on the cog, used as a local service boat.
Cog: broad, single-masted vessel, primitive in design but still working in parts of the world.
Dekares: immense cataphracted oared galley designed to transport infantry and marines.
Dogger: two-masted, sturdy, seagoing fishing vessel.
Holk: ponderous sea-going vessel that is highly fortified.
Junk: sailing ship favored by merchants, with river-going and sea-going forms, replete with isolated compartments.
Ketch: two-masted, large maneuverable ocean-going fishing vessel.
Knarr: light ship built for sea journeys but dangerous in heavy weather.
Yawl: light two-masted vessel used for lake fishing and communications.

The compiled list below allows comparison between these ships.


Strength indicates the number of defensive squares the ship has when attacked by ship’s weapons. Hardpoints describe the number of possible emplacements of ship’s weapons that the ship can carry. Draft is the depth of water the ship can move through without striking the bottom or running aground.

Quarters are enclosed rooms, usually large enough to provide comfortable space for two beds, or uncomfortable space for four. If there are more than two quarters on a ship, a captain’s quarters is usually included, which will be a space large enough for a full bed, desk, chair, map bureau and weapons locker. Berths are enclosed areas large enough for 8-12 persons each, depending on comfort. Additional crew are forced to find sleep where they can, noting that during bad weather most crew are working, while day-and-night ships allow beds to be shared among two to three crewmen.

Cargo describes all weight carried, including the weight of the crew, equipment, tools, furnishings and stores, in addition to weight carried for transport. Crew includes officers and ratings. Oarsmen are commanded by the crew. Construction time requires a full yard and two shipwrights per 8 hull or part thereof. Adding laborers will not improve construction time (as each part of the ship must be built by a controlled number of wrights before the next job can be initiated.

Yawl

Sleek, light two-masted vessel, very manoeuvrable and fast, used for lake and sea fishing, messages, envoys and communication. Despite the draft, the ship is commonly used for river travel. Similar to the ketch, with important distinctive design differences.

Yare: A
Dimensions: length (35 ft.); beam (9½ ft.); keel to prow (18 ft.)
Strength: hull (14 pts.); rigging (4 pts.)
Hardpoints: amidships (1)
Draft: 4 ft.
Staterooms: quarters (1); decks (1½)
Cargo: 9 tons
Crew: 7
Construction Time: 4 months

Dogger

Couldn't quite find an attractive picture of a 17th century
dogger; something like this but larger.
A development of the ketch, a two-masted gaff-rigged vessel carrying a lug sail on the mizzen, with two jibs on a long bowsprit. Short and wide-beamed, these are employed primarily as fishing vessels (giving their name to “dogger bank.”). Sturdy, scores were sometimes grouped together and used in war defensive naval battles against much bigger ships.

Features a single forward cabin with hardpoint on the bow.

Yare: C
Dimensions: length (45 ft.); beam (18 ft.); keel to cabin roof (17 ft.)
Strength: hull (15 pts.); rigging (8 pts.)
Hardpoints: forward (1)
Draft: 2 ft.
Staterooms: quarters (1); decks (1½)
Cargo: 20 tons
Crew: 11
Construction Time: 1 month

Ketch

Includes the crayer and similar to the yawl, a two-masted ocean-going fishing boat with a large fore-and-aft sail on the mainmast, which is taller than the mizzen. To assist going windward, a ketch will usually carry at least one foresail such as a jib or genoa. Some ketches will give a +1 movement bonus when reaching or running with the wind.

Yare: B
Dimensions: length (75 ft.); beam (18 ft.); keel to poop (38 ft.)
Strength: hull (30 pts.); rigging (8 pts.)
Hardpoints: amidships (4)
Draft: 8 ft.
Staterooms: quarters (2); berths (2); decks (3)
Cargo: 77 tons
Crew: 14
Construction Time: 7 months

Knarr

Also called the snaika, a ship built for long sea voyages. Wider, deeper and shorter than a Viking longship, these supplanted old ships as trade became more important to Scandinavia than raiding. Popular in northern Europe. Though dangerous, these ships are used to carry stores to Iceland, Greenland and Vinland, as well as trading goods with the British Isles and the Mediterranean.

The boat is covered with heavy skins stretched over a deep hull where cargo is stored. In heavy weather, waves will break over the top of the ship while it remains seaworthy.

Yare: C
Dimensions: length (50 ft.); beam (15 ft.); keel to prow (12 ft.)
Strength: hull (17 pts.); rigging (4 pts.)
Hardpoints: none
Draft: 2 ft.
Staterooms: quarters (1); decks (1)
Cargo: 13 tons
Crew: 8
Construction Time: 3 weeks

Junk

Describes the most common type of junk used by independent merchants in Eastern Asia. This sailing ship employs fully battened sails and has been continuously in use since ancient times. Built of teak from Guangdong, the multiple internal compartments and bulkheads are accessed by separate hatches and ladders, reminiscent of the internal structure of bamboo.

The hull has a horseshoe-shaped stern supporting a high poop deck. Seagoing junks incorporate a keel for sea travel (it is unreliable as an ocean-going vessel), but the river junk has no keel and relies on a daggerboard, leeboard or very large rudder to prevent the boat from slipping sideways in the water.

Junks employ stern mounted rudders; this allows height adjustment of the rudder to the depth of the water and reduces damage should the junk ground. The rudder is fenestrated with large diamond-shaped holes, adopted to lessen the force needed to direct the steering of the rudder. It is usually made of elm.

Carrack

A tall three-masted ocean-going ship developed from the cog, large enough to be stable in heavy seas, for a large cargo and for the provisions needed for very long voyages. Carracks are square-rigged on the foremast and mainmast, while being lateen-rigged on the mizzenmast.

They have a high rounded stern with large stern castle, with a slightly shorter forecastle. The stern castle is often stepped, with a lower fore and a higher aft. The height of the ship is part of its superiority, as it is difficult to board once grappled.

The Indian Carrack describes ships used by the English, French, Dutch and Portuguese to round the Horn of Africa to trade with the Far East.

Dekares

An immense cataphracted galley primarily designed to deliver a contingent of marines into a battle, as space for hundreds of marines is available upon the uppermost deck as well as below.

Cog

A broad, single-masted vessel with square rigging, high sides and a relatively flat bottom, stable enough to be sea-going but not safe for ocean journeys. The ship has a small castle both fore and aft. These ships are common in the Baltic Sea, where sufficient but controlled winds enable good navigation, while the hull is strengthened against sea ice. They are less practical in the Mediterranean, where the winds are not as strong much of the year or against the heavy winter seas.

Small Cog

Caravel

A small, highly manoeuvrable ocean-going ship, able to outdistance many larger vessels. The lateen sail gave it speed and the capacity for beating to windward, and are most popular with Portuguese and Castilians for the oceanic journey across the Atlantic. Typically they are fitted with two masts.

Having a shallow keel and being smaller than many cargo vessels, the caravel can sail upriver in shallow coastal waters. Its economy, speed, agility and power makes it esteemed as one of the best sailing vessels. It will outdistance pirates in heavier ships. The limited capacity for cargo and crew (many of whom have to sleep on deck) is its main drawback.

Yare: B
Dimensions: length (76 ft.); beam (20 ft.); keel to forecastle (35 ft.)
Strength: hull (30 pts.); rigging (8 pts.)
Hardpoints: forward (2); stern (1); amidships (2)
Draft: 5 ft.
Staterooms: captain (1); quarters (1); berths (2); decks (3)
Cargo: 105 tons
Crew: 14
Construction Time: 2½ months

Bireme

An oared galley with two decks of oars, with high speed and a shallow draft. These were equipped with a single masted fore-and-aft rigged square sail, to supplement the oarsmen in favourable winds. Because it can be beached, there was no need for a ship’s launch. The principal value in a galley is that the ship itself is the weapon, as it can be used to ram.

The bireme is not cataphracted, which means it does not have an upper deck. Covering in weather is provided by framing and canvas; the boat is beached at night for resting.

Type: light galley
Dimensions: length (80 ft.); beam (15 ft.); keel to upper deck (23 ft.)
Strength: hull (36 pts.); rigging (4)
Hardpoints: forward (2); stern (2); amidships (7)
Draft: 2 ft.
Staterooms: captain (1); officer berth (1); decks (3)
Cargo: 43 tons
Crew: crew (12); oarsmen (88)
Construction Time: 6½ months.

Barge (river vessel)

Common river vessels using the river’s current to float downstream with heavy loads covered by canvas. A low sleeping house is usually located amidship or near the stern, suitable for two persons comfortably or four cramped. Downstream, four polemen handle the craft, but a minimum compliment of oarsmen are needed for bringing the empty barge upstream. A half-full barge pulled upstream requires a full complement of oarsmen.

Scow (Light Barge)

Dimensions: length (60 ft.); beam (8 ft.); keel to house roof (11 ft.)
Strength: hull (20 pts.)
Hardpoints: none
Draft: 1 ft.

Holk

A kind of sea craft, the technological predecessor of the carrack and caravel. The ship is essentially a very large cog. Combining minimal lateen sails with two square-rigged masts, the holk is predominantly a cargo vessel used for low grade raw materials such as grains, stone, common foodstuffs, beverages and raw fibres.

Because of its relative speed, holks are built with two castles, one at the bow and one at the stern, for defence. A seagoing vessel, it is not safe for ocean journeys. These ships rarely travel alone and are usually attended by smaller, more nimble convoy minders. Convoys of these ships are more common than single vessels.

Yare: E
Dimensions: length (110 ft.); beam (29 ft.); keel to forecastle (37 ft.)
Strength: hull (44 pts.); rigging (12 pts.)
Hardpoints: foreward (2); stern (2); amidships (6)
Draft: 7 ft.
Staterooms: captain (1); quarters (5); berths (8); decks (3)
Cargo: 394 tons
Crew: 21
Construction Time: 88 days
