Since the VSR2 team set its sights on the outright speed record nine years ago, the record has increased by nine knots but the VSR2 team thinks they now have the boat to set a new record.
The boat itself doesn't look like anything you're likely to see at your local marina. Its main fuselage and beam are angled at 20 degrees to the direction of travel so that the boat points directly into the direction of the "apparent" wind to reduce drag and increase stability at high speed. The team claims that the entire 12.2 m (40 ft) long and 12.2 m wide boat - including the rigging - has the equivalent aerodynamic drag of a 74 cm (29 in) diameter sphere.
The boat's wing has an overall area of 22 m2 and sports a number of new features to make it more efficient and stable. It is thinner than the wing used on the VSR1, weighs around 65-70 kg (143 - 154 lb) and is inclined at 30 degrees to match the inclination of the opposing foil on the other side of the boat. Since the boat only needs to sail in one direction, the wing is asymmetrical and set up for a starboard tack to suit the Walvis Bay location where the record-breaking attempt is being made.
