The range of terms used to describe when the leading yacht deliberately tacks directly in front of the trailing yacht to cast their disturbed wind (gas) over them and slow them down. Luna Rossa has been using this to good effect when leading by forcing TNZ to sail a mode which compromises their speed. ![]() ![]() Being able to sail your own mode is important and the leading yacht is able to do this, while the trailing yacht is often compromised by what the leading yacht does. ModeĮach yacht has a configuration and angle to the wind at which it performs its best. The flight controller adjusts these constantly to ensure the foiling yacht is stable in its flight. The teams leave their decision on which jib to use up until the last possible minute – it is one of the few things they can change between races.Įach hydrofoil has a flap at the trailing edge which is used to control the flight ("ride-height) of the yacht. They are coded J1 (for the lightest wind strengths) up to J6 (for very strong winds). The teams have a range of jibs with differing sizes and shapes which are designed for different wind strengths. ![]() The triangular sail that is set at the front of the yacht. Named after American sailor John Kostecki. "JK"Ī manoeuvre that is a bottom mark rounding which leads straight into a tack (this needs both foils down). Powered by hydraulics, the grinders need to keep the pressure up in the accumulators to allow the helmsman to adjust this when he needs to. This is like the accelerator and needs constant adjustment. The track that adjusts the mainsail angle relative to the centreline of the yacht. This is controlled by the offside helmsman on Luna Rossa (hence the verbal "my pitch" handover call when they tack or gybe). The angle of the elevators (foil wings) on the bottom of the rudder which determines the angle of the hull relative to the water when flying (that is, bow down or bow up). Getting "in phase" with the wind shifts means you are using the wind-shifts to your advantage by being on the best angle to the next mark. As a result the angles the yachts can sail vary according to the wind direction changes. This is the most important data – but we are not seeing VMC reported on the television coverage. The speed the yacht is making towards the next mark. This is an important indication of which yacht is faster overall (as opposed to which yacht is faster through the water). The speed the yacht is making towards the direction of the wind (when sailing upwind) or away from the direction of the wind (when sailing downwind). This means the sails must invert in their shape to retain their aerofoil shape presented to the wind. The yacht turns away from the direction of the wind so that that the yacht changes the wind from coming from one side of the yacht to it coming from the other side. The yacht turns towards and through the direction of the wind so that the yacht changes the wind from coming from one side of the yacht to it coming from the other side. Team New Zealand and Luna Rossa are fighting for the America's Cup. ![]() The yacht is sailing at an angle to take it towards the wind direction (legs 1, 3 and 5 in these America's Cup races). The layline is the angle to the next mark which means the yacht does not have to do any more manoeuvres to reach that mark. The leeward yacht can turn up (called a "luff") and the windward yacht must turn in response to keep clear. As a result the windward yacht must keep clear of the leeward yacht. The leeward yacht when it is overlapped with the windward yacht has right of way. The yacht sailing further away from the direction of the wind when compared with their opponent. The yacht sailing closer to the direction of the wind when compared with their opponent. When sailing on port you must give way to the yacht sailing on starboard. The yacht is sailing with the wind coming from the left side of the boat (when looking forward). This is important because in the rules of sailing a yacht on starboard has right of way over the yacht on port. The yacht is sailing with the wind coming from the right side of the boat (when looking forward). With more interest than ever heading into the final days of racing, here's a guide from Orams to help you decode the language used in this year's event: Starboard (tack or gybe) If you've found yourself scratching your head at sailing terminology as the America's Cup hits fever pitch, AUT's Sailing Professor Mark Orams is here to help.

The location of the America's Cup varies with each edition. The 37th America's Cup, held in 2023, took place in Barcelona, Spain. The event featured international teams competing in state-of-the-art AC75 class boats, showcasing cutting-edge maritime technology. The chosen venue adds a unique backdrop to the competition, creating an exciting atmosphere for both participants and spectators. The America's Cup continues to travel to different host cities, contributing to the global appeal and prestige of this prestigious yacht racing event.
