Jolly Boats

Jolly Boats
A spelljamming ship can be outfitted with one or more jolly boats, which use the rowboat statistics in the Dungeon Master's Guide. In space, jolly boats are used to cross the gulf between two ships whose gravity planes and air envelopes intersect (on occasions when bringing the bigger ships alongside each other would be risky), or to travel to or from a pier that is either too small or too crowded to accommodate a larger vessel.
A jolly boat can be lowered into the gravity plane of a larger ship or object, where it bobs like a boat in water. A jolly boat is too small to support a spelljamming helm, so the crew must use oars to steer and propel it as it "floats" in the gravity plane. A jolly boat without a gravity plane to float in becomes uncontrollable, though its own air envelope has enough air to sustain one crew member for 8 hours or four crew members for 2 hours each.
