Folding Sand Vessel

This fine, wooden box is 12 inches long, 6 inches wide, and 6 inches deep. It can hold items like any other box. If a command word is spoken, the box unfolds itself to form a sand skiff {Sa 104} over the course of 1 round. Items in the box are deposited, unharmed, on the ground. A second command word causes it to unfold into a sand schooner {Sa 104} over the course of 5 rounds. A third word of command causes the vessel to fold itself into a box again, taking the same amount of time as unfolding.
