Authorities have suspended their search for the owner of a kayak found drifting 900 yards east of Plum Island on Tuesday, a U.S. Coast Guard spokeswoman said Wednesday night.

The search was suspended at 5:30 p.m. and will not be resumed, the spokeswoman said.

For the past day, it had remained unclear whether the watercraft was simply cast adrift or whether a kayaker was missing, a U.S. Coast Guard spokesman said earlier Wednesday.

"There's no change in the results," Coast Guard Sector Long Island Sound spokesman Lt. j.g. Martin Betts said earlier on Wednesday, adding that the Cutter Sanibel had been involved in the search, along with assets from Air Station Cape Cod; stations Montauk and New London, Connecticut; and Southold Town bay constables and police.

Someone on a fishing vessel spotted the empty kayak on the Long Island Sound early Tuesday, Southold Town Police Chief Martin Flatley said Tuesday. "They found a kayak with belongings inside it," he said.

Coast Guard photos show a red, one-person kayak with fishing rods and a net. There also was food inside, officials said.

The Coast Guard said the overturned kayak was reported by a Good Samaritan at 3:20 p.m.

Betts said the Coast Guard had searched with the Sanibel and a helicopter, along with town police marine units and a Suffolk police helicopter.

Searchers had scoured the waters for miles east and west of Plum Island, but as Betts said, they remain uncertain whether a missing person was involved.

No kayaker has been reported missing, Cmdr. Andrew Ely, chief of response for Coast Guard Sector Long Island Sound, based in New Haven, Connecticut, said Tuesday.

The 12-foot Pelican kayak has a hull identification number of CAZEP10662D515.

Flatley said there was no indication how long the kayak had been adrift, but he expected it was not for weeks and months, because fishing boats and ferries in the area would probably have spotted it.

The Coast Guard asks anyone with information to call them at 203-468-4444.
