Shortly after 11am, Dublin Coast Guard requested the Skerries RNLI volunteer crew to launch their Atlantic 85 lifeboat Louis Simson after receiving a report from another vessel of a motorboat in difficulty on the eastern side of Lambay Island.
The lifeboat, with Eoin Duff at the helm and crewed by Conor Walsh, Peter Kennedy and Rob Morgan, proceeded directly to the last known position of the craft to begin a search. At the time of the launch there was a Force 3 northeasterly wind with calm seas.
The motorboat was quickly located at anchor close to the island. A tow was established and the boat, with four people on board was brought safely to Rush Harbour.
Speaking after the callout, volunteer lifeboat press officer Gerry Canning said: "Sometimes, no matter how well prepared you are, things can go wrong at sea.
"Thankfully another boat spotted the danger and called the coastguard."
