SEATTLE (AP) — Fatigue and complacency led to a passenger and car ferry crashing into a terminal in Seattle last year, causing $10.3 million in damage to the ferry, according to the National Transportation Safety Board’s final report.
The Cathlamet ferry departed Vashon Island on July 28, 2022 and crossed Puget Sound with 94 people on board. It was approaching its dock in West Seattle when it struck an offshore piling part of the dock called a dolphin, the NTSB said in the report released Thursday. One minor injury was reported. The dolphin had $300,000 in damage, officials said.
The ferry captain “did not take any action to correct the ferry’s course, slow down or sound the alarm before the contact,” according to the report. Investigators said the captain also didn’t recall what happened and seemed unaware of how the ferry wound up hitting the pilings. Those events are consistent with incapacitation from a microsleep, a period of sleep lasting a few seconds, because of fatigue, NTSB investigators said.
“Mariners should understand the performance effects of sleep loss and recognize the dangers of fatigue, such as microsleeps,” NTSB investigators said in the final report. Mariners should avoid being on duty when unable to safely carry out their responsibilities, investigators added.
