An oil spill recovery vessel () is provided that comprises a catamaran bow section () with twin hulls between which an oil skimmer unit () is arranged for displacement between a lowered, operating, position in oil-polluted water and a raised, non-operational, position clear of the water. Aft of the catamaran bow section () is a trimaran main section () made up of a central hull interposed between two outer hulls formed by aft continuations of the twin hulls of the catamaran bow section (); the three hulls of the trimaran main section have conjoined upper portions. A propulsion unit () is operative to move the vessel () forward at slow speed for skimming operations, and, with the skimmer unit () in its raised position, at a fast speed in which the vessel planes on its trimaran main section (). 110.
