In the early hours of July 15, 2022, the 24-meter yacht Pegasus, which was originally built in 2012 by Fairline Yachts, became engulfed in flames while moored at the Peninsula Yacht Basin in Gig Harbor, Washington. The National Transportation Safety Board (NTSB) made an official report about the accident. The fire, which burned for approximately one hour, resulted in the complete destruction of the vessel. Fortunately, no individuals were on board at the time of the incident.

Firefighters arrived at the scene to find the aft section of the yacht fully consumed by the blaze. Despite their efforts, the flames proved difficult to extinguish, leading to the eventual sinking of the vessel at its berth. The estimated loss of the Pegasus is valued at $1.5 million, while a neighboring docked vessel suffered minor damage.
Moored at the outer berth of the Peninsula Yacht Basin pier, the Pegasus was partially obscured from shore view by other moored vessels. Security cameras at the marina captured the initial signs of smoke and flames emanating from the yacht's aft section at 2:04 AM. The fire continued to intensify and spread forward over the next 45 minutes.
At 3:02 AM, a bystander alerted emergency services, prompting the arrival of Gig Harbor Police officers and firefighting units. However, due to the fire's advanced stage, containing and extinguishing the flames became an arduous task. Firefighters deployed hoses from the floating docks and a firefighting boat, engaging in a relentless battle against the blaze. At 4:14 AM, the stern of the Pegasus sank, with the bow gradually descending as the vessel took on water. The fire was finally brought under control at 4:31 AM when seawater inundated the main deck cabin.
The investigation into the cause of the fire revealed that the Pegasus owner suspected fireworks as a potential trigger. However, security camera footage from the marina did not show any activity around the yacht before the fire's ignition. The owner and his employee disclosed that they had recently applied a name-brand teak oil finish to the vessel's wood surfaces. Rags soaked in the oil were improperly stored under a table on the aft deck, raising concerns of spontaneous combustion.

The Pierce County Fire Prevention Bureau's fire marshal determined that the fire originated on the aft deck, where the oil-soaked rags had been stored. The heat generated from the rags' self-heating properties likely led to the fire's ignition. This incident highlights the fire hazard associated with improperly discarded oil-soaked rags and serves as a reminder to follow manufacturers' instructions for cleanup and disposal of such materials.
The narrowness of the docks and the distance between the fireplug ashore and the Pegasus's berth hindered firefighting efforts. Nevertheless, given the significant growth and spread of the fire before it was reported, it is unlikely that the yacht could have been salvaged.
The National Transportation Safety Board (NTSB) has determined that the probable cause of the fire was spontaneous combustion due to the improper disposal of oil-soaked rags on the aft deck of the Pegasus. The NTSB emphasizes the importance of proper storage and disposal procedures to prevent similar incidents.
