BOSTON (CBS) — The city of Boston and the state have issued a cease and desist order to Bay State Cruise Company after a photo emerged of what appeared to be a crowded cruise ship this weekend.

They can no longer conduct music or group charters but can continue their ferry service to Provincetown.

Former Massachusetts State Rep. Marty Walz snapped a photo of people gathered closely together during a Saturday evening cruise on the Boston Harbor.

A statement from Mayor Marty Walsh along with the cease and desist order read: “This weekend’s mass gathering on a boat in the harbor represents a serious threat to public health, which is why today the Boston Public Health Commission together with the state’s Department of Labor Standards issued a cease-and-desist order to Bay State Cruise Company. We’ve made great sacrifices and worked hard over the last few months to stop the very real and very dangerous spread of COVID-19, and it’s vital every person and every business take this public health emergency seriously, and do their part to keep their families, neighbors and communities safe.”

Bay State Cruise Company said the Provincetown II was operating at 33% capacity and told WBZ-TV they have detailed safety protocols, “The general info is that in addition to providing ample space for social distancing, we are an outdoor venue with the benefit of a constant breeze across the decks as we sail at 9 knots.”

Experts say people still need to practice social distancing and wear a mask when they can’t do so in public spaces, even at the beach.

“You do get concerned that this may reflect in the next couple of days into an uptick in cases. In trying to encourage people to balance those risks, if you see that the beach is crowded, maybe going at times when you think maybe there will be less people,” said Dr. Gabriela Andujar Vazquez, associate hospital epidemiologist at Tufts Medical Center.

Lauren Anderson and her wife said they’re staying far from the crowds. We found the Northampton couple biking Monday afternoon.

“Until we find a vaccine, I’ll be worried,” said Anderson.
