Barge Aboard Catamaran
A BACAT (Barge Aboard Catamaran) vessel is very similar to a LASH vessel; BACAT vessels transport standardised barges too. The big difference however, is the way in which the barges are loaded and unloaded. Whereas the barges are loaded on or unloaded from an LASH vessel by means of a crane, they are loaded on and unloaded from a BACAT vessel whilst floating.
