Angle's new £2.7 million RNLI Tamar class all-weather lifeboat had her first shout on Sunday morning, when she went to the aid of a fishing vessel which had suffered electrical failure.
The lifeboat, Mark Mason, commanded by second coxswain Danny Richards, was on a training exercise when she was requested by HM Coastguard to assist the Clotan 2.
The fishing vessel, with three persons on board, was between Skomer and Skokholm islands.
When the lifeboat reached the scene, however, the electrical problem had been solved and no assistance was required.
The new Tamar lifeboat has been at Angle since March 17 and went operational a week later.
She is the RNLI's most technologically advanced lifeboat and is bigger and faster, 25 knots as opposed to 17 knots, than her predecessor, the Tyne class all-weather lifeboat.
Angle is the second lifeboat station in Wales to take delivery of a Tamar class lifeboat, the first being Tenby, where the Haydn Miller went into service in 2006.
