ABSTRACT:
A catamaran with pivotal fore and aft gates defining a well. When moved through a floating liquid spilling with the fore gate open the well collects spilling. The collected spilling may be pumped directly into a tank. Also, the catamaran is equipped with means to deploy a collapsible, floatable retrieval sheet over and into the well to confine the collected spilling, the aft gate being then opened to set the sheet adrift. A peripheral barrier of air bubbles concentrates the oil toward the center of the well.
