The International 110 is a sporty sailboat favored by a particular sort of idiosyncratic racing purist, folks who love camaraderie and a good time. At the 2022 International 110 National Regatta—the last one to be held at the Inverness Yacht Club—bar revenue hit a record. That’s a significant accomplishment, given that the club has been operating for 112 years. “Basically, we party for five days,” said Milly Biller, the club’s port captain. But they also race, quite seriously. These days, the event happens every two years, alternating between Hull, Mass., and Inverness, and it draws some of the world’s most accomplished sailors. The next one will be held in West Marin from Aug. 9 to 13; the course runs between Marconi Cove and Heart’s Desire, where the winds are a bit lighter than near the club. The 2022 race was a barnburner, with the top two crews separated by just three feet after seven rounds of racing. The winner was a sailing legend, Skip Allan, an Inverness Yacht Club member from Santa Cruz. Mr. Allen has raced with America’s Cup winner Ted Turner of CNN fame and skippered the Imp, a racing yacht out of San Francisco that is one of the most decorated of all time. Mr. Allan is also a survivor of the 1979 Fastnet Race, a premier international sailing event held in the United Kingdom. That year, a storm packing hurricane-force winds overturned at least 75 boats and sank five. Fifteen crew members died. In that era, crews did not have to radio in their location, and for a time, the Imp’s whereabouts were unknown. A New York Times account reported that the boat had capsized. “We did not die, even though the New York Times printed my obituary,” Mr. Allan told the Light. He was 77 when he won the 2022 Inverness race, when Sean Callagy, a local yacht club member who divides his time between Inverness and San Rafael, served as his crew. Mr. Allan won’t compete this year. With its low boom, the International 110 is challenging to operate, and Mr. Allan says he’s aged out of that class. “You hit your head on it, and you have to do a deep knee bend every time you tack upwind.” In all his storied racing career—which includes winning the 2,000-mile solo TransPac race from California to Hawaii—he considers his 2022 win on Tomales Bay one of the best. “We won the race by three feet and took the national championship,” he said. “It was a big deal, probably one of the biggest race successes I’ve had in my lifetime.”
