Detailed Ships

Your ship, rebuilt inside and out. Outside: rigging, crates and barrels, a small boat, a rudder and railings. Below deck: quarters for you and the crew, a kitchen, a cargo hold, an armory, a shrine to Kynareth, and sailors to talk to.

Detailed Ships is an entry in the Built-in mods database, listed under On.

Several of these change core rules, so the guide pages describe the game with them on. 'Fixed by the room' means online everyone plays with the mod at its shipped settings, whatever they choose offline.
