Keelboat
One of the smallest sailing vessels, keelboats can be sailed or rowed by a single person. These ships often transport small amounts of cargo or passengers. They're perfect for pleasure cruises, as they're easier and less expensive to operate than larger vessels.
A keelboat has the following features:
*Light: A hanging lantern or two casts bright light across the ship.
Rigging: Rigging on the ship can be climbed without an ability check.
Sails: The keelboat has one 10-foot-tall mast with sails.
Example Keelboat Crew
A keelboat requires a single crew member to operate smoothly. If the characters are guests on a keelboat, the crew consists of a single captain who has the statistics of a (CR 2) Bandit Captain with proficiency with water vehicles.
Keelboat Deck
The deck of the keelboat has the following features:
Ballista: A ballista is mounted on the fore of the deck. Ten ballista arrows are stacked and secured nearby.
Oars: The deck of the ship holds twelve benches and four 15-foot-long oars. When the ship is rowed, crew members sit on these benches to work the oars.
Railing: The deck has a 3-foot-high rail around its perimeter that provides half cover for Medium creatures and three-quarters cover for Small creatures behind it.
Keelboat Cabin
The keelboat cabin has the following features:
Footlockers: Beneath each bed is a footlocker. The footlockers are iron and have AC 19, 18 hit points, and immunity to poison and psychic damage.
Furnishings: Two beds and a desk with a chair stand at the aft of the cabin.
