SRD:Folding Boat

Boat, Folding: A folding boat looks like a small wooden box—about 12 inches long, 6 inches wide, and 6 inches deep. It can be used to store items like any other box. If a command word is given, however, the box unfolds itself to form a boat 10 feet long, 4 feet wide, and 2 feet in depth. A second command word causes it to unfold to a ship 24 feet long, 8 feet wide, and 6 feet deep. Any objects formerly stored in the box now rest inside the boat or ship.

In its smaller form, the boat has one pair of oars, an anchor, a mast, and a lateen sail. In its larger form, the boat has a deck, single rowing seats, five sets of oars, a steering oar, an anchor, a deck cabin, and a mast with a square sail. The boat can hold four people comfortably, while the ship carries fifteen with ease.

A third word of command causes the boat or ship to fold itself into a box once again.
