Folding boat

A folding boat is a small wooden box that can be commanded to unfold into a boat.

Description
When folded, this item looks like a foot-long box, which floats. When one of two command words is spoken, it unfolds into either a small or large boat.

The smaller boat is a ten feet long, four feet wide, and two feet deep sailboat with an anchor and a set of oars as well as the mast and sail. It can hold four medium creatures.

The larger boat is 24 feet long, eight feet wide, and six feet deep, with a square sail, five sets of oars and a steering oar, rowing seats, an anchor, and a deck cabin.

The third command word folds the boat back into the box provided all creatures have disembarked. Any objects in the boat larger than the box remain outside of it when it is folded.

History
When the Nein Heroez was capsized by an attack from a storm giant in pursuit of Fjord's last Cloven Crystal, Kingsley Tealeaf revealed he had a folding boat and unfolded it so that the crew could escape the sinking ship. They were able to sail on this boat to the nearby Twinward Isles.
