Barstool Sports founder Dave Portnoy and his mom had to be rescued by the US Coast Guard Monday after his boat suddenly lost power and went adrift off Nantucket.

“Your boys almost lost Captain Dave today,” the 47-year-old revealed in a video posted on social media.

The sea saga unfolded after Portnoy said he unhooked his 28-foot boat from a dock in one of the exclusive Massachusetts vacation island’s harbors — only to realize the vessel’s engine and breakers were dead. 

“No power, no radio, no anchor, no nothing; heavy, heavy winds,” he recalled in the two-minute clip. “Next thing you know, Captain Dave is lost at sea.”

After trying to navigate his boat through the crowded harbor, Portnoy — who last year shelled out a staggering $42 million for a waterfront property on the island — said he screamed for help and eventually fired a flare gun to attract attention.

Eventually, a female who was sailing nearby noticed him and boarded his boat.

“She boards Captain Dave’s vessel. She said, ‘Can I make a TikTok of you?’ I said, ‘No time for TikToks,'” he said.

The woman then radioed the Coast Guard for help, Portnoy revealed.

Coast Guard members who were conducting a training exercise nearby helped tow his boat back to land.

“Captain Dave lives to tell another tale,” Portnoy said as he thanked the agency.

The Boston-based First Coast Guard District later responded to Portnoy’s video, tweeting: “You’re welcome, Dave.”

“Tell Miss Peaches we said hi and remember to boat safe!” the agency added, referring to Portnoy’s 6-year-old American pit bull rescue.

Meanwhile, Portnoy claimed he may have second thoughts about going back out on his boat again.

“It’s a dangerous game, the sea’s angry, my friends,” he said. “Captain Dave may never go in the boat again.”
