Boat tie eater head is a 12-cell still life.
This still life is comprised of the normally stable boat having been tied to the normally stable eater 1. This is one of two possible ties, in which the boat is attached to the "head" segment of the eater; the other possible version, boat tie eater tail, has the boat attached to the "tail" segment of the eater instead.
Construction
