The AC-75 foiling monohull is radical even by America’s Cup standards. A 75-foot monohull with no keel, and 2 canting T “dagger boards.” These should be even faster than the 50-ft foiling catamarans.
The 36th America’s Cup will run in March of 2021. The first regattas start in September of 2019. So far there are the Kiwis (the defender) and 3 official challengers. (They are hoping for one or two more challengers.)
One team has built a 24t test platform, but there is limited video, since the teams focus on secrecy and security a lot. And also they seem to crash quite a bit. So the best video to date is the computer graphics explanation of the class. (Video from The World Sailing Show.)
Some things are too expensive even for the America’s Cup series. In 2013 they were racing 72 foot-long, hydrofoil catamarans. They were expensive to build, hard to control, and it seems they were suppressing the competition. So for the 2017 series, they went to smaller foiling catamarans. (40 or 42 feet, I can’t remember.) For 2021 they will be using foiling monohulls.
But the AC72 was a magnificent machine. (When YouTube freaks out over the privacy extensions in your browser, use that link above.)
Andrew “Bart” Simpson was killed May 9, 2013 during an AC72 training run. He was on Team Artemis.
Since I do this for my enjoyment (and not yours) I will include three bits from the world of sailing.
The serious news is that a British sailor was lost at sea in the Southern Ocean in the Volvo Ocean Race. Sailor lost during Volvo Ocean Race wasn’t tethered when he was knocked overboard
Volvo Ocean Race sailor John Fisher of Britain wasn’t wearing his safety tether when he was knocked off his sloop into the frigid, remote Southern Ocean in gale-force conditions just before sunrise Monday, according to a timeline released by Team Sun Hung Kai/Scallywag.
Fisher, 47, was lost at sea some 1,400 miles west of Cape Horn, with no other boats within 200 miles.
In the lighter news, the final rules about the next America’s Cup race were published. America’s Cup: AC75 Class Rule Published >> Scuttlebutt Sailing News
That is the design rules for the next class of boats. They are abandoning catamarans for the time being, and going to a foiling monohull. I guess the thinking is it will be less expensive to compete. They are also putting significant limits on the number of hulls, foils, masts etc. that can be built. This should also hold down the total cost. (There are 2 videos at the site, but they are probably only of interest to sailing nerds.)
The political news is a sign of the times. Sailing’s Barcelona World Race abandoned over Catalan uncertainty
The Barcelona Race is an every-four-years regatta of 2-man teams sailing around the world. (26,000 miles) It Starts and ends in Barcelona, the capital city of Catalan, but given political “unrest” in that part of Spain, the 2018-2019 race has been canceled.
The next America’s Cup will be raced on foiling monohulls. THE AMERICA’S CUP CLASS AC75 BOAT CONCEPT REVEALED
The Emirates Team New Zealand and Luna Rossa design teams have spent the last four months evaluating a wide range of monohull concepts. Their goals have been to design a class that will be challenging and demanding to sail, rewarding the top level of skill for the crews; this concept could become the future of racing and even cruising monohulls beyond the America’s Cup.
Emirates Team New Zealand currently holds America’s Cup and will defend at the next running. Luna Rossa is the officially designated challenger, and both have a say in the design.
One of the problems with foiling boats traveling at 40 knots or more, is that things go bad very fast. And if that results in a capsize, a catamaran is in need of help to be righted. The AC-75 boats will be fully foiling, and self-righting in the event of a capsize.
The 36th America’s Cup match race will be held in 2021. (Preceded as always by the Louis Vuitton Regatta to select the challenger.)
The Main Event at America’s Cup picks up later today, with Emirates Team New Zealand up 3-to-0 over Oracle Team USA. In the meantime, they’ve been running a superyacht regatta. Highlights from the America’s Cup Superyacht Regatta 2017 in Bermuda – 35th America’s Cup
A short video of the highlights of this week’s race.
Lionheart, with round the world racer Bouwe Bekking in charge, won the J Class and with it the top prize for the regatta.
The details of the J-Class are down in the weeds of yacht design, but they can be found at the Wiki. There are currently 8 boats racing that conform to the J-Class rules (as amended in 1937). 10 were built in the 1930-1937 era, but only 3 survived. The rest are recent builds with one boat being launched this year.
Day 2 Highlights video: Emirates Team New Zealand are ahead 3-0 over Oracle Team USA in first to 7 match. (I really love the fact that they have adopted the graphics techniques from NFL Football.)
Going on at the same time is the Superyacht Regatta. These boats are not as super-high-tech as the foiling catamarans in the main event, but they are worth a look
Some of my sailing friends complain that the America’s Cup boats (The America’s Cup Class – ACC for short – foiling catamarans) are not very practical as boats go. Gunboat has a production foiling cat that is almost (almost) a racer-cruiser. But I haven’t been able to figure out what they cost. (If you have to ask…)
So in addition to the ACC boats in the official races, there is also a regatta of more traditional boats. But they are superyacht sailing vessels. The smallest enrolled to compete in the regatta is Wild Horses, and it is just a bit longer than 76 feet.
Still, they are beautiful boats. And they are sailing this week in Bermuda. (While we wait between the end of Louis Vuitton Cup and the start of the America’s Cup. Here’s a video to whet your appetite.)
