Three people were taken to the hospital when a 72-foot yacht burned and sank in New Hampshire, authorities said.

The vessel, the Elusive, was on the Piscataqua River heading toward a marina in New Castle at about 4 p.m. Saturday when a passenger noticed black smoke below deck, the New Hampshire Department of Safety said in a statement, according to CBS 13.

The Coast Guard and the New Hampshire State Police Marine Patrol posted photos of the flames and thick black smoke pouring from the vessel.

Three passengers, as well as two dogs, jumped overboard as the boat became engulfed in flames. They were rescued by other boats.

The passengers, identified by authorities as Arthur Watson, 67, and Diane Watson, 57, both of New Canaan, Connecticut; and Jarrod Tubbs, 33, of Jupiter, Florida, were brought to a hospital where they were treated and released.

Despite efforts to save the yacht, it drifted into Maine waters and eventually sank about two hours after the 911 initial call, authorities said.

The fire remains under investigation.
