British sailor Tony Bullimore was trapped for four days in an upturned yacht that was filling up with "bitterly cold" water in the Southern Ocean.

Untangling a sail which was wrapped around a foil was a major task With winds of about 50mph (80km/h) and 16ft (5m) waves, keeping the boat in one piece has sometimes been a challenge in itself.

It started out when he purchased and refurbished one boat off Ebay, and through his passion, and the subsequent support from the Scaramouche Sailing Trust, it grew into a more sustainable project.
