MAMARONECK, N.Y. (CBSNewYork/AP) — The Coast Guard says it’s suspending its search for a boater missing in the Long Island Sound.

Crews looked for Scott Donsavage for more than 24 hours after he went missing around 10 p.m. Tuesday, the agency said Thursday.

The 43-year-old was last seen by his wife departing from a boat launch in Mamaroneck. His 15-foot vessel was found ashore in gear with no one aboard.

The Coast Guard said it brought in helicopters from Cape Cod, Massachusetts, and Atlantic City, New Jersey, to help in the search.

The agency said it covered more than 276 square miles, roughly eight times the size of Manhattan.

Donsavage is from Pleasantville, The Journal News reported. He is described as standing 5 feet, 11 inches tall, weighing 180 pounds. He was wearing a black shirt, red hat and shorts.
