Two of Britain's most famous solo skippers, Mike Golding and Dee Caffari, move into the next stage of their ground-breaking technical alliance to develop the fastest Open 60 possible ahead of this year's gruelling solo round the world yacht race, the Vendee Globe 2008/09. Caffari and Golding, who between them have circumnavigated the global on eight different occasions, have developed an intensive testing programme to find a competitive advantage over the 30-strong Vendee Globe fleet and in particular the impressive French contingent. The two skippers announced the technical alliance, the first of its kind between British Open 60 teams, in March 2007. The alliance led to the construction of two identical sister-ships in Aviva and Ecover 3 and this summer Caffari and Golding will be testing the two boats against each other to maximise performance. The Aviva Ocean Racing and Ecover teams are taking a leaf out of Formula 1's book and believe in the merits of testing against similar machines. The upcoming period of two-boat testing will set the two Open 60s against each other much like the way F1 teams do with their two cars. One of the boats will be set as a control whilst the other makes changes to the sail trim, ballast and keel angle to determine the most effective set up. The ultimate aim is to find the optimum performance that will give the skippers an edge to challenge the French dominance of the Vendee Globe race. To date each of the five editions has been won by a French skipper.
