The Boat
A Transat 650 yacht is a 21-foot sailing boat, purpose-built for a downwind speed-run over the Atlantic. Hover over the illustration below for more information.
In the spirit of the very first Transat 650, the boats have been created to be a cost-effective alternative to the big ocean-racing classes.
Today there are two classes competing in the ‘Classe Mini’: A selection of approved ‘Series’ designs and a more extreme ‘Prototype’ class. The latter has become a designer’s playground for the big racing yachts like the Open60s or the Volvo70s.
This means that most of sailing’s greatest developments have first been tested “small-scale” during the Transat 650. To this day the class continues to push the boundaries of technology with innovations like ultra-light carbon fibre constructions or wing-masts.
Whilst designed for the Transat 650, Minis have also become one of the most active offshore classes: Over 7800 nautical miles worth of double-handed and crewed races are organised regularly by the French Classe Mini in France, England, Spain and Italy.
Sails
Mini Transat boats are allowed to carry a maximum of 8 sails, tailored to a range of different conditions. This usually includes a mainsail, reefable jib, trysail, stormsail, a code zero and three spinnakers.
Daggerboards
As the keel is angled to windward two asymmetric daggerboards are needed to prevent the boat from drifting sideways. Only one will be used at a time while the other one is pulled out of the water.
Cabin & Cockpit
The cabin of a Mini is only about 4m² big, which is why most of the time is spent in the cockpit.
All sails, food and gear are stacked down below, making a small space even smaller.
Most skippers only use the cabin to sleep in, to prepare food and navigate.Rudders
As a Mini is extremely wide, it needs two rudders to retain steerage. One ruder regularly comes out of the water.
Minis are equipped with a very capable auto pilot to steer the boat while the skipper is sleeping or changing sails.Keel
A lead bulb at the bottom of the keel keeps the boat upright. In a mini the bulb contains almost half the weight of the boat, making them very stable. Often the prototypes have a pendulum keel allowing them to further shift it to windward to balance the boat.
