There is a button on the bow of your boat. You are not supposed to press it.

About this mod Author’s original text

blir-u-boat

Received more or less a good idea to re-create old Finnish imageboard copypasta to How To Fish.

Copypasta:

be 17 years old

first internship on a ship

boss is an absolute jerk

shows me some button that you "måste inte painaa"

(must not press) because otherwise "båten blir u-båt"

(the boat becomes a submarine)

night shift

smoking a cigarette on the car deck

highly illegal because underage and car deck

lighter drops into some narrow crack

reach for it, accidentally hit the button

bow_visor_open.exe

båten blir u-båt

<After 28.9.1994, never again to a cruise ship

TL;DR Press button and the boat becomes a submarine, for a limited time.

How it works

| Phase | Duration | What happens |

|---|---|---|

| Alarm | — | Button depresses, alarm starts, boat still afloat |

| Diving | ~7 s | Boat eases under. Alarm cuts when fully submerged |

| Submerged | 15–25 s | Boat is a submarine. Steer it if you can get to the wheel, visibility is limited |

| Surfacing | ~4 s | Back up, buoyancy restored |

Stay aboard and you won't drown. Step off and the game's normal drowning rules apply, which is your problem, not mine.

Multiplayer

The host must have the mod. Boat physics are server-authoritative, so the host executes the

dive and every client sees it through the game's normal position sync, including clients without the mod.

| Setup | Result |

|---|---|

| Everyone has it | Full experience. Anyone can trigger it, nobody drowns aboard |

| Host has it, others don't | They see the boat sink and ride it down, but have no button, no alarm, and will drown on board |

Known issues

  • If someone looks at the sinked boat from an island, the boat is not filled with water
  • If boat is sinked too near of an island, it may get stuck to the ocean floor
  • When boat is recovering from submarine mode, it may fly high in the air
  • Multiplayer triggering by a non-host player is untested, let me know if it does not work

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.

Install these first, or the mod will not work:
