A number of boats have been damaged in Cobh as a result of Storm Ellen, the local sailing club has stated.
The marina facility at Whitepoint, which opened earlier this summer, has now been closed upon the advice of the Coastguard.
In a statement, Cove Sailing Club said they were "saddened" to report that boats had been damaged.
A more comprehensive inspection is expected to take place when the wind and rain abates.
"Due to the impact of Storm Ellen between 21:00 and 00:00 yesterday, a number of boats at the marina facility at Whitepoint Cobh suffered damage.
"The Coastguard conducted an initial assessment at 07:45 and upon their advice, the facility has been closed.
"Forecast conditions today are not favourable to allow a fuller inspection.
"The office at Cove Sailing Club will be open today to facilitate further information updates," the club stated.
"As a club of volunteers, we are saddened that individual boat owners have suffered damage and loss to their boats but we are grateful that there has been no injury to anyone as a result of the impact of Storm Ellen.
"We will issue further updates when we are in a position to carry out a more comprehensive inspection," they continued.
Speaking to, Eddie English, owner of SailCork, said two boats broke free during the violent gusts last night, one of which sank.
"Two of the larger boats broke free.
"One of the boats was an Oyster 44, she was blown ashore at the beach at Whitepoint.
"She was high and dry with the waves beginning to break over the keel last night when I was out.
"The good news story is that this morning, there were a number of people got her off the beach and got her to the safety of the Naval Base in Haulbowline," he said.
"Unfortunately, the other boat wasn’t so lucky. The other boat belonged to a visitor.
"She’s called a Hallberg-Rassy. It’s a top end type boat.
"She broke loose and did a lot of damage to herself and a lot of other boats in the marina and became wedged in the western side of the marina until the wind changed direction and she was then forced to the eastern side of the marina and wedged herself there.
"We could actually hear the fibreglass being permeated by the concrete when she got to that corner and she sank about a half an hour to an hour after that.
"She’s unfortunately on the bottom now," Mr English continued.
A number of other boats have been damaged but Mr English said the damage is "nothing very serious".
Boats have been moved off the marina while it is being repaired.
Mr English said he has cancelled all events in the sailing school today but normal operations will resume from tomorrow.
