Liveaboard Disaster in the Seychelles March 26, 2026
On March 13, the Galatea, a 100-foot Turkish-built steel-hulled gulet accommodating up to 14 divers, sank in bad weather near Marie-Louise Island, in the Indian Ocean, around 160 miles southwest of Mahé, the Seychelles capital. According to one source, ten people were rescued and transported to Desroches Island by dinghy, including a Swiss woman who was later found at sea. Three others, including the vessel's French owner and two Swiss guests, remain missing, and the search has been suspended. Authorities were considering dispatching a salvage vessel to tow the Galatea into shallower waters so it would be easier for divers to access the interior and search for bodies, but we have not received word whether they proceeded.
Daft Diver Jeopardizes His Passengers March 26, 2026
When you're the only one who can drive the boat, best not to leave it to go diving. That's what the skipper of a small boat off Wellington, New Zealand, did on March 5. His two passengers became alarmed when suddenly winds up to 55mph drove waves as high as six feet. The 18-foot sports fishing boat began to be blown out to sea as night approached. They phoned the police, and rescue vessels and a helicopter were dispatched. An inflatable transferred a boat driver to the stricken vessel. The captain/diver, missing his boat, had made it to the shore.

Something for Super-Macro Fans March 26, 2026
Divers photographed a tiny marine invertebrate, a sea squirt less than an inch long, off the coast of Japan, and it turned out to be a new species. Nicknamed the "skeleton panda," its markings resemble a panda's face set against a bony frame. The white parts that look like bones are the blood vessels, and the black parts on the head that look like a panda's eyes and nose are just patterns. It attaches itself to hard substrates and pumps water through siphons to extract plankton and other small organic materials. (Daily Galaxy)
Some Full-face Snorkeling Masks Prove Dangerous March 26, 2026
The Consumer Product Safety Commission has warned people to stop using OUSPT full-face snorkeling masks, made by Field Life of China, of which 84,000 units have been sold through Amazon. The full story will be in the April issue of Undercurrent.
Leaving Jail, Wreck Hunter Stays Taciturn March 26, 2026
In December 2015, American shipwreck-salvager Tommy Thompson was imprisoned for civil contempt by an Ohio District Court. He had refused to comply with orders to disclose the location of 500 gold coins taken from a historic shipwreck. Their whereabouts continue to remain unknown, since the 73-year-old Thompson refused to say a word about them and was released from prison this March, after serving more than a decade behind bars. In 1988, Thompson led an expedition that located the Atlantic wreck of the passenger and mail steamship Central America. Carrying a cargo of California Gold Rush bullion, it sank in 1857 during a hurricane.
