Abstract : The introduction of ocean-going catamarans into the fleet produced questions as to the seakindliness of these vessels. Quantitative observations abroad the USNS HAYES and the ASRV-21 prompted an interest in the motion statistics of this class of vessel. The ASRV-22, ORTOLAN, sister ship to the ASRV-21, was delivered from Mobile, Alabama to Philadelphia Navy Yard. During the transit, measurements of roll, pitch and vertical acceleration were recorded. Reported are the results of those measurements, environmental conditions under which the data was recorded and comparisons with comparable data recorded abroad the USNS HAYES are presented in graphic from.
