Skillful sailing meets new technology – Daniel Fitzgibbon and Liesl Tesch of Australia are the first to have been guaranteed gold with a race to spare at this year's Paralympic sailing events. Fitzgibbon, a quadriplegic, has used state-of-the-art technology to be able to compete.
From court to sea – Tesch only took up sailing two years ago, having formally won a Paralympic medal with the Australian wheelchair basketball team.
Sydney to London – Sailing only became a Paralympic sport at the 2000 Sydney games following a trial at Atlanta four years previously.
Level playing field – There are just three sailing classes but a huge number and variety of disabilities. Sailors are classed by the severity of their disabilities on a scale of one to seven, one being the most severe, seven the least.
Last day's action – As the action moves into the last day, the medals in the three classes will be decided with the Dutch team looking strong in the Three-Person Keelboat (Sonar) class.
Hosts end medal drought – But Thursday will also see Great Britain win its first ever Paralympic sailing medal. The hosts are guaranteed at least bronze in all three classes.
