The first at 5pm involved a Jeep-type vehicle spotted floating in the harbour. Satisfied that no one was in the vehicle, the officer in charge watched it sink rapidly before deploying two safety marks.
Fifteen minutes later, a call came from a mender of the public who spotted kayaks in difficulty at Dalkey Sound, with one casualty clinging to the side of a kayak.
The Dun Laoghaire Coast Guard march team sighted the group trying to make passage to Coliemore Harbour and advised to alter course to Bulloch as they were fighting against the tide and wind and making poor progress.
A third callout at 6pm saw the team stood down en route to a person in difficulty due to the tide at Merrion Strand after they made it ashore safely.
