The Vendée Globe is a single-handed, around the world race that allows no outside assistance. The 8th race will begin on 6 November, 2016.
Here is a look at the preparation for the race. It shows a nice look at what the boats are like.
All boats competing in the 2016-2017 version of the race conform to the IMOCA 60 Open Class rules. Among other rules, the boats have to be able to self-right, if capsized. That is helped by the swing keel which can put a lot of weight over 1 side of the capsized hull. (You get a brief glimpse of the test on one boat at about 50 seconds into the video).
A lot of my sailing friends gave me grief over the catamarans of the America’s Cup races, because of how high-tech they were. (Foiling, etc.) Well in the video you can see these boats have a swing keel, lee boards AND a j-foil to aid in righting moment. This enables them to carry a LOT of sail. Everything is high-tech today.
