The Foiling NACra 17
The Nacra 17 is a high performance catamaran and the only boat in the Olympics that mandates a mixed crew. We're very proud of our class for having men and women compete against each other at such a high level, and we hope that it will inspire more mixed crews in other areas of sailing.
The boat has changed since its introduction in 2013, going from a semi-foiling boat on C-foils to a fully-foiling boat on Z-foil dagger boards and T-foil rudders. With this new configuration the Nacra17 will be able to foil downwind in as little as 6 knots, is stable in 25 knots and flat water, and will hit speeds of over 20 knots. It will be the fastest boat in the Olympic Games, making it the most exciting boat to sail! (in our unbiased opinion)
new foil shapes
The Z foils are bent in two different places to allow the boat to remain completely out of the water from the start to finish (though most people only foil downwind for VMG purposes). The original N17boards were simply curved, known as C-foils, which allowed for 3-5 seconds of flight when going downwind.
The T foil rudders have elevators on the bottom of the rudder that help create stable flight. The original rudder simply went straight down, so the T foil will be a nice addition!
