Prince William and Kate Middleton Thursday made their first official joint appearance since their engagement last November, launching a lifeboat on a rainy little island in Wales, and RadarOnline.com has the pics. More importantly, it also marked Kate's first official royal duty.

The couple officially named the "Hereford Endeavour" lifeboat during a ceremony at the Trearddur Bay Lifeboat Station in Anglesey, North Wales.

William and Kate actually live part-time on the remote island and will live there for the first two years of their marriage.

William works in Anglesey as a search-and-rescue helicopter pilot. He's been on duty there this week where he helped rescued a woman who had fallen off a cliff. Sadly, the woman was later pronounced dead at the hospital.
