This is a new world record for a single crossing of the North Atlantic from new York to lizard point (the southernmost point of Britain) to monohull yachts with a length of 60 feet. This achievement today has established 26-year-old Swiss Alan mourning isn yacht La Fabrique class IMOCA Open 60.
Need not to doubt: this is the real world record. However, now it is yet to ratify the world Council for the registration of world records under sail (WSSRC). Any violations of the rules seemed to be no (at least, they are not reported). So, I think, will ratify.
The achievement definitely an outstanding previous record in 2013 belonged to the French Brand Hillamo, improved from 12 hours, 25 minutes and 20 seconds!
In the following year of mourning isn at its La Fabrique will start round-the-world Vendée Globe. And now to be serious.
