attempt to reclaim the 500m world speed sailing record. Pilot Sean Langman
and copilot Martin Thompson. The Wot Rocket project team assembling the
half sail boat/sail plane at Kurnell in Sydney¹s south before testing
for the world speed sailing record attempt commences on Botany Bay. With
light autumn NE/NW winds forecast for rest of the week however, there
may be few, if any, windows with enough grunt to get Wot Rocket rocketing.
The Wot Rocket is half sailboat/sail plane; a nine meter long canoe style
hull with two tiny foils, each about a sixth of the size of a Moth foil
and a nine meter rigid sail, then a traverse beam out of an aerodynamic
twin pod crew compartment. It is built entirely from carbon fiber and
weighs approximately 400 kilos.

The difference between this sailboat/sail plane and any that have come
before it is that it will be attempting to break through the water speed
barrier using a technology as yet untried on any sailing craft ­ supercavitation
– to reduce the drag which is around 1,000 times greater in the water
than in air. Supercavitation will in effect mean Wot Rocket flies in a
gas bubble created by the outward deflection of water by a specially shaped
nose cone and the expansion of gases from its fin and foil design. By
keeping water from contacting the surface of the body of Wot Rocket, this
will significantly reduce drag and allow extremely high speeds. The concept
behind the Wot Rocket approach is to induce supercavitation at lower speeds
where control can still be maintained and from there push through to the
top speeds. Supercavitation means Wot Rocket should only require a fraction
of the 45-50 knot winds that Albeau needed to go 0.39 knots better than
the previous record. A moderate 18-20 knots should do the trick believes
