Abstract : A Mission Data Recorder (MDR) was designed and built by the Coast Guard R&D Center to support the Operational Test and Evaluation (OT&E) of the 47-Ft Motor Lifeboat (MLB). The purpose of the MDR was to collect both short-term event data and long-term vessel motions data in an autonomous manner, similar to an aircraft flight data recorder. Phase 1 results were published in Coast Guard Mission Data Recorder (MDR) for the 47-Ft Motor Lifeboat, Report No. CG-D-20-94. Phase 2 follow-on data collection includes the recording of one significant event which was recorded during a towing operation. Statistics data for the Phase 2 period of June 1994 to March 1995 were collected and analyzed. Heave acceleration and roll frequency distribution curves were developed for each boat. The MDRs will remain onboard the 47-Ft MLBs for an additional year to continue monitoring for significant motion events and to collect data on how the boats will be used following the close scrutiny of the OT&E.
