Dun Laoghaire lifeboat rescued seven people on a yacht which got into difficulties in heavy fog on Tuesday night. The Pippa IV was training crew in Dublin Bay when the fog closed in around dusk. The yacht grounded at the western end of the bay. The lifeboat was paged just after 9.30 p.m. With visibility down to 100 metres, the lifeboat found the Pippa IV at 9.55 p.m. and towed it back to safety.
