Windstar Cruises has restarted sailing with vaccinated passengers and crew on board.
The small ship line has returned to service with four-mast sailing yacht Wind Star embarking on a seven-night cruise from Athens to the Greek islands.
The vessel is carrying a maximum of 148 passengers on the itinerary which includes Patmos, Santorini and Mykonos.
The company plans for the vessel to sail the itinerary weekly dates until October.
Windstar is returning to operations in a phased manner, with its fleet of six ships sailing on various dates up until November.
Passengers will be required to have vaccines among health and safety precautions including testing, social distancing, masks, and high-tech air filtration.
Windstar is ensuring that crew are vaccinated on all ships when they begin sailing on revenue cruises.
It was among the first cruise lines to require jabs for passengers, with a goal of full crew vaccinations.
The company said: “Procuring doses for Windstar’s primarily international crew has been challenging, but line officials have now successfully sourced vaccinations for crew aboard all six yachts.”
