The vessels are around 57 feet long, carry 10 guests in five cabins and will be progressively introduced by June next year.

Vince Donnelly, G Adventures’ director of global sailing, said: “All five boats have been fitted with solar panels and state-of-the-art engines and generators that minimize environmental impact without sacrificing performance. 

“Recycled and natural materials have been prioritized in the boats’ construction, ensuring all materials used are free from harmful substances.”

Each itinerary is led by a G Adventures ‘Skipper CEO’ or chief experience officer. Shore excursions are designed to ensure travellers interact with locals and support communities that may not usually see a lot of tourists.
 
“This commitment to the environment and spreading tourism dollars to lesser-visited communities on smaller Greek Islands really sets the bar high for operators in the region, and ensures we’ll deliver an incredible experience for our travellers that is simultaneously kind to our planet and its people,” said Donnelly. 

Prices are from £1,199pp for an eight-day itinerary excluding flights.
