|poss=[[Deep_Crystal_Cave_(3.5e_Location)|Deep Crystal Cave]]; '''Potnia Nadadora''': A ''Folding Foiled War Canoe'' with ''Everfull'' sails. The ''Folding Foiled War Canoe'' 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 catamaran 10 feet long, 4 feet wide, and 2 feet in depth. A second command word causes it to unfold to a hydro-foiled trimaran (three hulled catamaran) 24 feet long, 8 feet wide, and 6 feet deep. Any objects formerly stored in the box now rest inside the boat or ship. A third word of command causes the boat or ship to fold itself into a box once again.
