We traveled to 27 countries in one year – without taking a single flight

Whatever floats your boat.

Two globetrotters have spent the past 15 months traveling the world without taking a single flight.

Tommaso Farinam, 25, and Adrian Lafuente, 27, are “sustainable explorers” who have moved between continents taking trips on aliens’ sailboats.

Airplanes – which emit around 90 kg of CO2 per passenger per hour, depending on the aircraft – are absolutely prohibited.

“We are ‘ship hitchhikers,'” Farinam, who hails from Italy, told Luxury Travel Daily. “We found one of our ‘trips’ on Facebook, talking to a boat captain who offered us a seat.”

The frugal and eco-friendly move means the pair spent just $7,700 (£5,900) each visiting 27 different countries.

Farinam and Lafuente began their global adventure last summer, traveling around Europe on a shoestring budget.

They then spent 39 days at sea, sailing across the Atlantic to reach South America.

The pair also crossed the Gulf of Panama, which was anything but smooth sailing.

“The first 10 days in the Gulf of Panama can only be described as absolutely terrifying,” recalls Farinam. “We had very unfavorable winds, storms and big waves constantly. It was very scary at first to think that we might turn upside down.”

However, the pair are not willing to trade the sea for the sky.

After exploring most of South and Central America, the pair are sailing the Pacific Ocean in hopes of reaching Australia.

“It’s been about three months since we started and we’ve visited several islands in between!”

They plan to explore Down Under for a few months before heading to Asia by boat.

Farinam and Lafuente are sharing their story with fans online as part of “Project Kune” – which is their commitment to show the world that flying-free travel is more than possible.

“Our goal is to help create hope for a world where we, humans, are able to live in symbiosis with the rest of the vegetation, animals and other people,” Farinam said.
