The Coast Guard responded to a 21-foot boat off of Prudence Island around 10:00 Sunday morning.
The boat's anchor line got caught in the props, and the engine couldn't operate. The 3 occupants on-board feared they were drifting towards the rocks and considered abandoning ship.
The Bristol Harbormaster was first to arrive on-scene, and Coast Guard Castle Hill sent two boats to assist. One boat helped to pull the troubled boat away from the rocks and towed it safely back to shore.
