Jean-Jacques Savin set out on the wild seas of the Atlantic with a dream: "to laugh at old age." Three weeks later, the 75-year-old Frenchman was found dead in the ocean, his support team said.
Portugal's coastguard recovered Savin's overturned boat off the Portuguese archipelago of the Azores on Friday.
They were able to send a diver down on Saturday to search it, his team added.
The former paratrooper's body "was found lifeless inside the cabin," they said.
The avid triathlete set off from mainland Portugal's southern tip on Jan. 1, but there had been no contact with him since overnight Thursday to Friday when he activated two distress beacons.
Savin was hoping again to reach the Caribbean, this time in a rowing boat eight meters long and 1.70 meters wide (26 feet long and 1.5 feet wide), with a rowing station at its center.
His team earlier on Saturday said they were "very worried."
"We haven't heard from him since 00:34 (1:34 a.m. GMT) yesterday (Friday) morning," they said, adding that he had activated "two distress beacons, telling us he was 'in great difficulty'."
His daughter in a Facebook post said a search operation "was immediately set in motion in coordination with the French, Portuguese and U.S. sea rescue services."
He was last heard of north of Madeira, Portuguese islands off the northwest coast of Africa, on his way to Ponta Delgada in the Azores.
Shortly after leaving on Jan. 1, unfavorable wind conditions had forced the adventurer to extend his trip by 900 kilometers (550 miles).
On Wednesday, he had reported "strong swell and ... wind" on Facebook, adding that he had been forced to switch from using an electric water desalinator to a backup one operated by hand.
"It's costing me physical energy," he wrote.
But "be assured, I am not in danger."
Savin, who said rowing across the Atlantic was a way to "laugh at old age," celebrated his 75th birthday on Friday last week on board his two-cabin boat.
He left with it packed with 300 kilos (660 pounds) of equipment, including freeze-dried food, a spear gun to fish and a heater, as well as the two desalinators.
To celebrate his birthday, he had also brought along his mandolin, foie gras and champagne.
"I'm off on holiday to the open sea," he had said before leaving.
"I will row eight hours a day and when the wind blows too hard, I'll close myself in," he said.
He was looking forward to an extra safety measure that he did not have during his last barrel crossing: a tracker to make him visible to the radars of passing cargo ships.
After returning from his last trip, he had written a book to recount his journey.
The following year, when the coronavirus pandemic hit, he gave advice to fellow Frenchmen on how to avoid cabin fever during confinement.
"Everyone needs to embrace their passion ... Start drawing, learn to play the harmonica, if it doesn't bother the neighbors," he said.
He said he appreciated the solitude of his 2019 trip, adrift in a barrel on the ocean.
"I wrote my journal, I read a lot, I exercised," he said.
Through a porthole in the floor, he was able to admire passing schools of fish. And sometimes, he spotted dolphins.
