An Experimental Investigation of Alterations Proposed to Improve Seaworthiness Characteristics of the ASR 21/22 Catamaran.

摘要

The David W. Taylor Naval Ship Research and Development Center undertook to experimentally determine which of a group of possible fixes considered would best improve the seaworthiness characteristics of the ASR 21/22 catamarans. Extensive seaworthiness experiments were carried out with the as-built condition as well as various modifications to determine the feasibility of these possible fixes. A 15-foot foil forward in conjunction with cutting away a portion of the forward end of the bridging structure is considered the most desirable of the modifications considered.
