LIFEBOAT crews have rescued crewmembers on board a yacht struck by engine failure off Portland Bill.

Weymouth RNLI All–Weather lifeboat was launched at the request of Solent Coastguard amid reports of a 40 foot yacht in trouble yesterday at around 6.40pm.

The vessel had issued a 'Pan Pan' radio message - meaning, 'I need assistance, but it is not life threatening.'

The lifeboat headed to the last reported position of the yacht some 18 miles SW of Portland Bill.

On arrival, the lifeboat found that the yacht, which was on passage from Dartmouth to Hamble, not only had engine failure but also had a battery which was failing - meaning the crew would shortly be without radio communications.

"Having established that the four persons on board were all fit and well, the lifeboat took the yacht in tow back to Weymouth," an RNLI spokesman said.

Arriving at 10.45pm the yacht was moored up close to the Harbourmasters Office.

The lifeboat returned to station refuelled and made ready for the next shout.
