Savin turns 72 on January 14 and is saving a bottle of red wine for the occasion.
A French septuagenarian, armed with a block of foie gras and a couple of bottles of wine, has set sail across the Atlantic in a barrel.
France 24 says Jean-Jacques Savin is hoping to reach the Caribbean within three months thanks to ocean currents alone.
The current voyage is not being carried out under the same spartan conditions, with the 3-meter-long barrel accommodating a 6 square-meter living space including a kitchen, sleeping bunk and storage.
"For the time being my capsule is behaving very, very well and I've got favourable winds forecast until Sunday", he added in a phone interview. It also includes a small window from which he can watch the fish below him.
A former military parachutist who served in Africa, Savin has also worked as a pilot and a national park ranger.More news: Cleveland Cavaliers to sign Patrick McCaw, Golden State Warriors restricted free agent

In his most recent update on Facebook Thursday morning, he posted a selfie and said that everything is fine.
A 71-year-old Frenchman has departed on a journey across the Atlantic in a specially constructed barrel capsule, created to use ocean currents alone to propel him across the sea.
He plans to drop markers during his journey to help oceanographers from the JCOMMOPS worldwide marine observatory study Atlantic currents.
Savin has a budget of 60,000 euros (£54,000) for his expedition, covered in part by barrelmakers and a crowdfunding campaign. It also has a solar panel that generates energy for communications and GPS positioning.
Savin is undecided about where he hopes to end up. He will attempt to reach the Caribbean with only ocean currents and trade winds propelling his capsule, according to a Facebook page set up to document his project, where he plans to post daily updates, including Global Positioning System coordinates tracking the journey. Landing on a French island, he noted, would make the paperwork easier for a French citizen like himself.
