A sailor who was knocked unconscious near the Northport Yacht Club on Tuesday evening is in stable condition at a hospital after he nearly drowned, Coast Guard officials said.

The Coast Guard Station Eatons Neck said they overheard a report of a boater who had called the Northport Yacht Club when his crew member went overboard after he was hit in the forehead by the sailing vessel's boom. The man was found facedown in the water without a lifejacket and bleeding from a gash on his forehead when the Coast Guard arrived on scene. He had inhaled a large amount of water, causing him to start sinking, the Coast Guard said.

Rescuers brought the man on board and took him to Northport Town Dock, where an ambulance arrived to take him to Huntington Hospital, officials said.

In a statement, Petty Officer 2nd Class Jovan Morales, a boatswain's mate stationed at Eatons Neck, warned against the dangers of going out on the water without a lifejacket.

"Luckily, another person was able to grab hold of him until we got there," Morales said in the statement. "Had he been wearing a lifejacket, he could have stayed afloat on his own, possibly stopping him from inhaling so much water."
