This report presents and discusses the results of seaworthiness trials conducted aboard the USS ORTOLAN (ASR-22) prior to the installation of a between hull forward foil. Ship motions, hull strains, and cross structure impacts are presented and comparisons are made between the ORTOLAN, the USNS HAYES (T-AGOR-16), and several monohulled ships. Current seaworthiness problems associated with the ASR Class are defined and discussed. Results indicate that while ship motions are not abnormal for a ship of this length, the frequency and intensity of cross structure impacts degrade the seaworthiness of the craft to a point which is unsatisfactory.
