Lifeboat crews sprang in to action when a yacht ran into difficulties off the Great Yarmouth coast today, with a casualty on board.

The RNLI Trent Class lifeboat Samarbeta and the inshore lifeboat Seahorse IV were called out at 2.30am after reports of a yacht grounded at the south end of Scroby Sand.

The yacht, Moon River, was thought to be on its way from Grimsby to Lowestoft when the incident occurred.

Both lifeboats had to negotiate very shallow water when they arrived on scene, sometimes working in less than half a metre.

As the tide was about to turn it was decided to try to remove the casualty from the stricken yacht.

The offshore lifeboat provided guidance and floodlight cover while the inshore lifeboat removed the casualty and then transferred her to the offshore lifeboat.

The stricken yacht was salvaged and towed back to Yarmouth once the woman was safe.

Coxswain Paddy Lee said he was very pleased with the outcome and the yacht was very lucky to be salvaged.
