The owners of a battery-powered boat are attempting to break the World Electric Boat Endurance Record on the River Thames.

Pike, a restored 1901 river launch owned by Richard and Ann Leeson, of Goring, set off on Monday to try to complete 30 non-stop trips between Goring and Wallingford, beating its own unofficial world record of 116 miles set four years ago.

The batteries have been fitted by the Thames Electric Launch Company. The company's managing director, Emrhys Barrell, said: "We hope to do 130 miles at 4.5mph without recharging the batteries.

"Independent invigilators will be watching to verify the event for the Guinness Book of Records."

Mr Barrell said electric boats were becoming increasingly popular because of their environmental advantages over petrol and diesel models, and because they are quieter and smoother.

The batteries can be recharged using an extension lead from the bank, and can last up to eight years.

Mr Barrell said Pike was capable of at least 8mph with the electric propulsion. However, the speed limit on the River Thames is 5mph.

The electric voyage started from Goring Thames Sailing Club at noon yesterday. The turning point upstream was just north of the Wallingford by-pass bridge.

Pike was due to complete the 130th and final mile of its journey at Goring at 6pm tonight.

The "Chloride Motive Power" batteries being used for the record attempt are made by a company in Bolton, Lancashire.
