Woman Dead, 3 Hospitalized After Mast Snaps on Schooner Co-Owned by 'Parks and Recreation' Actor

The Grace Bailey is partially owned by actor Marc Evan Jackson, according to the boat's website

A woman was killed and three others were hospitalized after a schooner’s mast snapped and fell on top of them during an apparent cruise.

The United States Coast Guard said it responded to the scene about a mile east of Rockland Harbor in Maine around 10 a.m. local time on Monday, after personnel from the 118-foot schooner — called the Grace Bailey — informed them that the broken mast had injured several people onboard.

One woman apparently sustained a serious head injury when the mast split and fell on top of her and the others, according to The Courier-Gazette, which described her as a passenger on a foliage cruise.

The woman was eventually transported to shore, where she was pronounced dead, the Coast Guard said in a press release. Her identity has not been released.

The Coast Guard then went back to pick up the three other people who were also injured in the incident. After getting back to shore, they were transported to Pen Bay Medical Center in Rockport.

The surviving victims' conditions have not been released.

The schooner is owned in part by actor Marc Evan Jackson, who has appeared in shows such as Parks and Recreation, The Good Place and Brooklyn Nine-Nine. The 53-year-old television star frequently posts about the Grace Bailey on his Instagram page, as well.

Jackson’s agent did not immediately respond to PEOPLE’s request for comment.

The sold-out cruise began Thursday and was set to conclude on Monday, according to the Grace Bailey’s website.
