Natasha Lambert sails by breath control as she cannot use her hands, so uses a small tube the size of a drinking straw fixed in a helmet which helps keep the straw in place.
This straw in-turn connects to the ram and the steering system of the boat. Using various micro processors and large electronic rewind winches, Natasha can also adjust the sails when she changes the mode of the straw by flicking a tounge switch (an LED switch within the straw.)
A sip takes the boat to starboard (turns right) and a puff to port (Left) or sail trim, a sip to bring the sails in and a puff takes them out. It only takes very tiny movements and the system is very responsive. The system uses open source software and programmes written by Our Dad, Gary Lambert.
