The average speed results from the course were: Elco 77-footer (PT-21), ; Higgins 76-footer (PT-70), ; Higgins MRB and Philadelphia Navy Yard boat (PT-8), . Accelerometers were again installed in the pilot house of each boat, but the readings were incomplete because the violent motion of the boats made observations difficult and in some cases necessitated abandonment of the observing stations. Further, many of those taken were beyond the normal range of the instruments and were considered inaccurate. Elco boats were found to pound heavily and confirmed previous reports of crew discomfort.
