Former F1 designer David Chisholm revolutionary concept.
An adventurer is aiming to sail into the record books as the fastest woman on the water in a revolutionary boat so light she can carry it on her shoulder.
Hannah White's cutting edge dinghy might be 18ft long but because it is built from space-age materials it weighs just 1.5 stones - the same as a toddler.
Thanks to a state-of-the-art hydrofoil the specially designed vessel will 'hover' 3ft above the water with next to no drag, allowing it to hit speeds of almost 50mph.
The current record stands at 34.74 knots - or 40mph - set by British windsurfer Zara Davis in 2006 and in order to break it White, 31, will have to average faster over a mile-long course.
The boat, called Speedbird, was designed by former Royal Navy engineer David Chisholm, an expert in composites like carbon fibre, and built in a shed in Suffolk.
