US Coast Guard Concludes Investigation into Fatal Collision off Puerto Rico

The US Coast Guard Atlantic Division has completed its investigation into a fatal collision between a Coast Guard cutter and a small fishing vessel off Puerto Rico. The collision occurred on August 8, 2022, resulting in the death of one person aboard the fishing vessel, named Desakata, and injury to another. Vice Admiral Kevin E. Lunday, commander of the Coast Guard’s Atlantic Region, initiated a full investigation on August 11, 2022. The investigation found that neither the USCGC Winslow Griesser nor the Desakata saw each other and failed to take appropriate action to prevent the collision. Various factors contributed to the ships not seeing each other and avoiding a collision.

Vice Admiral Lunday explained the findings of the MII Board in a note, stating that the Desakata was an evasive ship in a crossing situation with the Winslow Griesser, which was on the starboard side of the fishing vessel. The Desakata had a responsibility to take early and substantial action to avoid the cutter. The board determined that the Desakata had failed to maintain a proper lookout, while it couldn’t objectively establish whether the Winslow Griesser had kept a proper lookout. However, there was sufficient evidence that the cutter failed to maintain an adequate lookout, preventing its crew from taking timely action. The board also noted that both vessels were not maintaining a safe speed.

Despite attributing the collision to the Desakata’s failure to keep a proper lookout and maintain a safe speed, the memorandum acknowledged critical actions by the cutter’s crew that could have prevented the collision. Vice Admiral Lunday emphasized the importance of upholding the highest standards of seamanship and navigation. The purpose of the investigation is to determine any claims for or against the United States, as well as any administrative action against those responsible. An independent investigation by the National Transportation Safety Board will also determine the cause of the accident and make recommendations for prevention.

Following the investigation, Lt. Cmdr. Benjamin Williamsz, the commander of Winslow Griesser, was temporarily relieved of his duties. Rear Admiral David C. Barata, commander of the Coast Guard Personnel Services Center, permanently fired Williamsz on May 9, 2023, citing a loss of confidence in his ability to command effectively. Lt. Vincent Deegan has since assumed permanent command of the cutter. The Action Memo and MII Report can be accessed for further information.
