Barge with long tail is an 11-cell strict still life.

This still life is comprised of the normally stable barge with a normally unstable long tail attached.

It can be substitutively referred to as the shillelagh with barge, with the pre-block of the shillelagh replaced with a barge, however "barge with long tail" is usually preferred for this object.
