A boat designed to break the world speed sailing record is continuing its trials in Portland Harbour.

The Sailrocket has been specially designed for the attempt.

Boat designer Malcolm Barnsley and pilots Helena Darvelid and Paul Larsen have been waiting for the right combination of wind and tide to test the vessel, which has a solid wing for a sail.

In the meantime, they have been making small adjustments to the craft.

Project leader and Sailrocket pilot Mr Larsen from Wyke Regis said the team aims to first break the harbour record, then the women's outright speed sailing record and then the men's world speed record, which stands at 48.75 knots.

The ultimate aim of the project is to break 50 knots.

Mr Larsen said: "We eventually did get on the water. The wind was only 10-14 knots maybe, but Sailrocket hit 20.8 knots while bearing away to avoid the shallows.

"She constantly surprises all of us with her light wind performances.

"In one sense it was a little frustrating not punching out the big numbers we are after, and you are all waiting for, but by the end of the day I felt happy. The rig was finally right and we were in control from start to finish. All in all that's good progress and I am confident now that she is ready for a record attempt."
