The Collision and Immediate Aftermath
On September 26, 2026, the 52-foot sailing yacht Tai Tam was struck by a pod of sperm whales about 250 nautical miles north of Norfolk Island. Australian crew member Jemma Cooper described a “loud thud” that pushed the vessel sideways and threw her from the steering wheel. The impact smashed the starboard steering gear, cracked the hull’s fiberglass, and flooded the interior. Crew members reported seeing six to eight whales alongside the damaged boat.
Rescue Operations
Approximately 30 minutes after the impact, at 1 p.m. New Zealand time, the crew activated their EPIRB and issued a Mayday. The Royal New Zealand Air Force dispatched a P-8A Poseidon patrol aircraft, which established two-way radio contact and coordinated the response with maritime rescue centres in New Zealand, Australia and New Caledonia.
Around 6 a.m. on September 27, the 470-foot container ship MV Sofrana Surville arrived as the first rescue vessel. All four sailors—Jemma Cooper, Jeremy Cooper, Terry Hetherington and Martin Jaffre—were lifted from their life raft onto the cargo ship and taken to the nearest port.
Vessel and Crew Details
- Tai Tam – a monohull sailing yacht, length reported as 52 ft, 51 ft, and 16 m in different accounts.
- Crew – Australian couple Jemma Cooper (helm) and Jeremy Cooper (skipper), New Zealand crew member Terry Hetherington, and French sailor Martin Jaffre (joiner).
Marine-Mammal Context
Adult male sperm whales measure 50–60 ft (? 18 m) and are classified as “vulnerable” by the IUCN. This incident follows a July collision that sank a fire-department vessel off New Jersey, marking at least the second recent boat loss to a whale.
Official Statements & Responses
The Royal New Zealand Air Force emphasized that the P-8A Poseidon’s rapid deployment enabled continuous communication with the stranded sailors and facilitated the redirection of nearby vessels to the scene.
