United States Coast Guard MISLE Incident Investigation Report For IYANOUGH - Allision & Grounding On 16Jun2017 21:35:00 EDT MISLE Activity Number: 6187583 MISLE Case Number: 1083961 MISLE Incident Investigation Report I. INCIDENT INVESTIGATION – GENERAL INFORMATION On 16 June, 2017 at approximately 2135 local time, the high speed catamaran passenger ferry IYANOUGH (subchapter K), travelling from Nantucket, MA to Hyannis, MA on its last run of the day at a cruising speed of approximately 32 knots, allided with the west breakwater jetty near Hyannis Harbor and ran hard aground. The vessel was carrying 48 passengers, six crew, and three concessionaires. The allision and grounding caused severe damage to the ship's hulls with two penetrations below the water line on the starboard side and an approximately one foot inset/penetration in the port side above the water line. The center hull was also holed and damaged. All three hulls had multiple additional scrapes and indents for approximately 30 feet starting from the bow. Fifteen people were transported to Cape Cod Hospital for evaluation and triage; seven of the fifteen had injuries beyond first aid and were treated and released by the next day. Drug and alcohol testing was completed on the crew directly involved. As a result of its investigation, the Coast Guard has determined that the initiating event for this casualty was the allision with the Hyannis Harbor breakwater. The causal factors that contributed to this casualty include: (1) a loss of situational awareness by the bridge crew, (2) the 1st officer's lack of familiarity and training with the vessel, (3) the master's distraction due to helping the 1st officer energize the spotlight at a critical time during transit, (4) perceptual confusions by the master relating to the radar images, (5) reduced visibility due to the weather conditions and time of day (winds in excess of 30 knots, 6-8 foot seas, patchy fog, rain/drizzle, sunset at 2018, and last light at 2052), (6) the speed of the vessel (32 knots), and (7) the IYANOUGH's operations manual was not in compliance with Navigation and Vessel Inspection Circular (NVIC) NO. 5-01.
