Kipp, Kipp, Ahoi! (2004)

A dexterity game in which players stack cans of goods in a rubber raft, and then turn screws that change the tilt of the raft, hoping to avoid tipping over the stacks.

Listed as being for Ages 5 and up on the Ravensburger website, although it may be a bit optimistic to play this touchy dexterity game with five year olds.
