As I stated a few pages back, it's fitted with all kinds of automatic doodads and whatnots, electronic sail trimming and raising, automatic spinnaker launch and retrieval. The reason that the crew of 5 are flying to NY is because running a ship single handed is fucking tiring and stressful so more crew to take over shifts is a good thing.
Which is why I’m tres cynical about this ‘unsupported’ claim by Team Greta.
These yachts when they race have a huge support operation in train. Race and Rescue coordinations at a race HQ, charted support vessels and rescue tugs along the route, chartered aircraft provide air observation, friendly navies lay on ship and air support, all yachts race on AIS and in the event of an incident, the nearest yachts go to the assistance of the yacht in trouble.
But here we have team Greta saves the world, travelling AIS off and claiming to be 100% unsupported.
