Video dinner parties, spa days, stuffed animals, favorite hoodies and cozy, colorful fleece blankets. Cole Brauer’s Instagram feed hardly feels like the work of someone racing a 40-foot sailboat around the world in the Global Solo Challenge. But Ms. Brauer, 29, is not an average ocean racer.

In 2022, Ms. Brauer had tried out for another competition, the Ocean Race, which is considered the pinnacle of professional ocean racing. Sailors in that race are highly trained, wear matching foul weather gear and have corporate sponsors. And most of them are men. Ms. Brauer, who had sailed thousands of miles on high performance ocean racing boats, felt she was ready to join their ranks.

But after competing in trials in France, Ms. Brauer was told she was “too short for the Southern Ocean” and was sent on her way.

In spite of her small stature — she stands 5 feet 1 inch — Ms. Brauer rounded Cape Horn, Chile, on Jan. 26, the last of the three great capes of her journey to finish the Global Solo Challenge. It is a feat most of the Ocean Race sailors picked instead of her have never even attempted. And despite being the youngest competitor in the race, she is ranked second overall, just days away from reaching the finish line in A Coruña, Spain.

Along the way, her tearful reports of breakages and failures, awe-struck moments during fiery sunrises, dance parties and “shakas” signs at the end of each video have garnered her a following that has eclipsed any sailor’s or sailing event’s online, even the Ocean Race and the America’s Cup, a prestigious race that is more well known by mainstream audiences.
