Ships as dungeons is an interesting challenge because they are mobile, limited in size, and waterborne. Expanding some definitions, however, can lead to a variety of possibilities you may not have thought of.

1. Redefine What A Ship Is

A ship doesn’t have to be this thing that floats on water. Maybe it’s an elven airship that sails through the skies or a submarine that inhabits the depths. Or perhaps it could be a dwarven ship that sails through solid stone in the Elemental plane of Earth or is the deceased hull of what used to be a dragon turtle.
Other options are to have the ship on lava or traveling within ley lines in your world’s magic system or even in space.
In cases like these, the players would be stuck on the ship until they could figure out how or where to exit

2. Examine Different Types Of Ships

There’s always the classic haunted pirate ship. But even these can be changed up by rearranging the levels and having hidden passages. Why not set a dungeon on a giant version of a Viking ship?
Or have the dungeon be an old-fashioned paddle wheel steamboat, a cargo ship, or a prison ship. If you don’t mind borrowing from modern day, consider a cruise ship or a canal ship as a location.

3. Consider Expanding The Location In Unique Ways

In Zelda: Skyward Sword, there are these items called “time stones” that shift a portion of the level back and forth through time.
Another way you could expand the location is to have the ship occupy two or more dimensions simultaneously, and the players have to shift from one to another to get to different places in the ship.
A third way to expand the location is for parts to have different gravity rules, but under different circumstances, so players never know whether or not they’ll be affected.
Finally, there could be different areas to explore, depending on the character’s size. Maybe part of the ship needs to be explored while they’re the size of an ant.

5. Consider Different Races

In designing a ship as a location, think not only of standard fantasy races but variations of them. For instance, you might have a group of Avariel (winged elves) who are sailing above the treetops, or tinker gnomes, with their penchant for all things mechanical, in some sort of steam-driven airship, and wearing magic-punk collapsible hang gliders that allow them to rain death from above.
Or you might have powrie (bloody cap dwarves) who use their heat-proof barrel boats in lava.
Also think of other intelligent races that might want to travel, but may not wish or be able to travel to a location normally. For instance, you might have dragons that have starships, beholders who sail within the ley lines, or lizardmen who explore the deep in submarines.

5. Consider The Reason For The Dungeon To Be There

Ask yourself “what’s the story behind why this is here?”
Stumped for answers? Consider the following ideas:

  • Protection of a magical item. The dungeon moves around because it protects a magic item that, if it fell into the wrong hands, would mean the end of the world. The creatures and traps are a test of merit. Those who fail are not worthy of the ultimate treasure.
  • Lost in time. In Zelda: Skyward Sword, the ship dungeon was lost to the annals of time, the area gradually became desert, and the ship fell into disrepair.
  • Consider the opening sequence as narrated by James T Kirk: “Space, the final frontier. These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.”
  • A prison. Maybe everyone and everything on this ship is there to keep something inside, and others out. Maybe the traps, automated guards, etc. are the ship’s defenses to prevent the criminal’s escape.
  • Creative genius. The dungeon might be a ship because the person (or people) building it simply could. They wanted to challenge others with their creativity, but also wanted to make it a challenge to even get there, so they made it.
  • The result of an experiment gone bad. Similar to the prison scenario, the magic or science experiment is too dangerous to remain free in the general sense of the term, so it was put into this ship and set adrift. It could be free as in the case of the Minotaur wandering its maze, but in this case the experiment would be wandering the ship.

6. Change the circumstances on the ship

A ship that’s afire is a vastly different experience than one that is sitting in a calm sea. As can a violent storm that tosses it about. Adding hazards of smoke, rotting wood, cold, low light conditions, or radiation can totally change the character’s experience, as can being underwater, in the vacuum of space, in an active volcano, and so on

  38. Galliot: several types of ships —
    • Mediterranean, (16th century–17th century): a type of ship with oars, also known as a half-galley, then, from the 17th century forward, a ship with sails and oars. As used by the Barbary pirates against the Republic of Venice, a galiot had two masts and about 16 pairs of oars. Warships of the type typically carried 2 – 10 small caliber cannons, and between 50 and 150 men.
    • North Sea (17th century–19th century)” a type of Dutch or German 20 to 400 GRT trade ship, similar to a ketch, with a rounded fore and aft like a fluyt. They had nearly flat bottoms to sail in shallow waters. These ships were especially favored for coastal navigation in the North Sea and Baltic Sea. To avoid excessive leeway, or leeward drift due to their flat bottoms, smaller vessels were usually fitted with leeboards. After 1830, a modernized type of galiot was developed that featured a sharper bow similar to a schooner. These vessels rarely had leeboards.
    • Naval ships (17th century–19th century) a French term for a type of naval warship that might have two masts with lateen sails and a bank of oars. It might also be relatively small with only one mast, and be little more than a large chaloupe or launch.

A galiote a bombes was a French term for a galiote armed with a mortar and
functioning as a bomb vessel, i.e., a vessel armed to shell coastal forts, towns, and the

  1. Gunboat: a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies

  3. Junk: A Chinese sailing ship
  4. Karve: A small type of Viking longship
  5. Knarr: A large type of Viking cargo ship, fit for Atlantic crossings
  6. Liberty ship: An American merchant ship of the late Second World War period, designed for rapid building in large numbers. (The earliest class of welded ships.)
  7. Longship: A Viking raiding ship
  8. Man-of-war: A sailing warship.
  9. Mistico: Small, fast two or three-masted Mediterranean sailing vessel.
  10. Monitor: A small, very heavily gunned warship with shallow draft. Designed for coastal operations.
  11. Nef: A large medieval sailing ship
  12. Paddle steamer: A steam-propelled, paddle-driven vessel, a name commonly applied to nineteenth century excursion steamers.
  13. Pantserschip: A Dutch ironclad. By the end of the nineteenth century, the name was applied to a heavy gunboat designed for colonial service.
  14. Penteconter: An ancient warship propelled by 50 oars, 25 on each side.
  15. Pink (or Pinque): One of two different types of boats.
    • The first was a small, flat-bottomed ship with a narrow stern; the name derived from the Italian word pinco. It was used primarily in the Mediterranean Sea as a cargo ship.
    • In the Atlantic Ocean the word pink was used to describe any small ship with a narrow stern, having derived from the Dutch word pincke. They had a large cargo capacity, and were generally square rigged. Their flat bottoms (and resulting shallow draught) made them more useful in shallow waters than some similar classes of ship. They were most often used for short-range missions in protected channels, as both merchantmen and warships.
  16. Pram: A small dinghy, originally of a clinker construction and called in English, as in Danish, a praam. The Danish orthography has changed so that it would now be a pråm in its original language. It has a transom at both ends, the forward one usually small and steeply raked in the traditional design.
  17. Pre-dreadnought: A type of battleship of the late 19th century to early 20th century, characterized by having a mixed offensive battery, in contrast to the “all-big-gun” Dreadnought type battleships.
  18. Q-ship: A commerce raider camouflaged as a merchant vessel.
