How do America’s cup races work?

The America’s Cup is the oldest trophy in international sports, dating back to 1851. It is a prestigious yacht racing competition that takes place every few years between the defender and the challenger for the America’s Cup trophy. The races involve high-tech hydrofoiling monohull yachts sailing on race courses marked by buoys. The competition location rotates between different host nations. Winning the America’s Cup requires strategy, advanced boat design and technology, expert sailing skills, coordination among the racing crew, and funding from sponsors.

When and where are the America’s Cup races held?

The America’s Cup races are held every 2 to 4 years, whenever a challenging club issues a formal challenge to the current defending club. The America’s Cup protocol determines the specific timing. The event location also rotates between different host nations, based on the defending club and the venue they nominate. Recent and upcoming editions have been held in Valencia, Spain (2007 and 2010), San Francisco, USA (2013), Bermuda (2017), and Auckland, New Zealand (2021 and 2024).

What is the history and origin of the America’s Cup?

The America’s Cup was founded in 1851 when the New York Yacht Club won the Royal Yacht Squadron’s Hundred Guineas Cup, then called the 100 Pound Cup, off the coast of England. This first race became known as the America’s Cup after the winning schooner named America. After winning the trophy, the New York Yacht Club placed it in a trust, requiring individuals to deed their racing yacht to the club to be eligible to challenge for the Cup. For over a century, the New York Yacht Club successfully defended the Cup against all foreign challengers.

The tradition that the Cup is held in trust for perpetual friendly competition between nations started with this first race in 1851. The Deed of Gift, drafted in 1887, formalized the structure and rules for future races. The America’s Cup went from a transatlantic race between one American and one British yacht into a modern competition involving multiple challenging yacht clubs and boats from many nations.

How do teams qualify to compete in the America’s Cup?

The America’s Cup is a match race between two competing teams or yacht clubs – the defender and the challenger. The defending team is the yacht club that currently holds the America’s Cup. The challenging team is the yacht club that wins the Prada Cup and earns the right to challenge the defender for the America’s Cup trophy. To qualify, the challengers must file a formal challenge accepted by the defending club.

There are generally multiple challenging teams from different countries. They compete in the Prada Cup selection series and playoffs to determine which one will become the final Challenger that faces the Defender. The challenging teams typically need to secure funding from sponsors, build or procure an IACC class yacht, and organise a sailing team, in order to compete for the Prada Cup.

What are the current specifications for America’s Cup class yachts?

The current class of racing yacht used in the America’s Cup is the AC75 foiling monohull. The specifications were created in collaboration between defending team Emirates Team New Zealand and challenger of record Luna Rossa Prada Pirelli after the 2017 races.

Key AC75 yacht specifications include:

  • Length – 75 feet (22.86 m)
  • Beam – 26 feet (7.9 m)
  • Displacement – 7,500 kg
  • Mast height – 37.5 m
  • Sail area – 365 m2
  • Foiling arm articulation
  • Hydrofoils for lift
  • Soft sails instead of rigid wings

These high-tech monohull yachts are capable of reaching speeds over 50 knots (92 km/h) as they “fly” over the water on hydrofoils. The class rules aim to balance technology innovation with affordability and spectacle for racing.

What is the protocol and format for the America’s Cup match?

The America’s Cup protocol is the set of conditions, rules, and agreements governing that edition of the event. It is negotiated between the defending club and the challenger of record yacht club after each Cup edition. Key components of the protocol include:

  • Timing, location, yacht specifications, and race format for that edition of the Cup
  • The selection process and rules for challengers competing to qualify
  • Regulations on design, technology, and construction of yachts
  • The racing conditions, courses, program, and scoring system
  • Details on measurement, equipping, and crewing the yachts
  • The rules for breaking ties, protests, arbitration, penalties and umpiring

The America’s Cup match itself is a best-of-13 head-to-head race series between the qualified defending and challenging teams. The winner is the first team to score 7 race wins. Races take place on windward-leeward courses marked by inflatable gates, with a race time target around 25-30 minutes.

How are the crews chosen and composed for America’s Cup teams?

The crew size for AC75 boats is limited to 11 sailors under the current protocol. America’s Cup teams undergo extensive selection processes to assemble their sailing and shore crew members. Ideal crew members possess an elite level of fitness, sailing skills, teamwork and specialised expertise in roles like trimmer, grinder or tactician.

Crews normally include:

  • Skipper – oversees sailing, strategy and crew
  • Helmsman – steers the yacht
  • Tactician – plans the strategy and compile crew inputs
  • Mainsail trimmer – controls mainsail
  • Headsail trimmer – controls jib sail
  • Grinders – provide manual power to operate winches
  • Bowman – manages the headsail and weight distribution

The shore team comprises designers, engineers, operations staff, and team managers who provide technological, analytic, logistics and financial support. The syndicate head oversees the entire team’s preparation. Crews may also include guest sailors from sponsoring yacht clubs.

How are the sailing rules enforced in America’s Cup match races?

The America’s Cup match races are officiated by on-the-water umpires along with a jury to ensure fair racing and adherence to the racing rules. The umpires follow the races in fast powerboats equipped with live video feeds, sensors and other technology. They can issue penalties in real time and are in radio contact with the competing yachts.

Common race rule violations that warrant penalties include:

  • Making contact with the opposing yacht
  • Crossing the race boundary lines
  • Obstructing the other yacht’s tack or gybe
  • Fouling a mark of the course
  • Using illegal propulsion like oars or engines
  • Dangerous sailing to cause injury or serious damage

Penalties involve performing one or more penalty turns of 360° before resuming racing. Jury reviews can adjust race scores and disqualify teams for extreme violations.

How is technology advancement incorporated in the yacht designs?

Cutting-edge technology is intrinsic to the America’s Cup. The AC75 class was conceived specifically to push the boundaries of hydrofoiling monohull performance. Competing teams leverage computational fluid dynamics (CFD), structural finite element analysis (FEA), innovative materials like carbon fiber, and onboard sensors to develop the fastest possible yachts.

Areas of innovation include:

  • Hydrofoil control systems – Software and actuators to adjust foil angle and flap for optimal lift and stability.
  • Flight control systems – Automated trim and control of the foils and wingsail when foiling.
  • Structural design – New approaches to carbon fiber fabrication and layout for an ultra-stiff, lightweight yacht platform.
  • Daggerboard design – Shapes and angles to control leeway while also generating vertical lift when foiling.
  • Wingsail design – Shapes designed for aerodynamic lift and efficiency across sailing angles.

The class rule limits constrain development in areas like hull dimensions, crew size, and sail area. But within those limits, the teams apply extensive R&D and testing to maximize performance factors like stability, speed, and maneuverability when sailing the yachts.

What logistics, facilities, and infrastructure support America’s Cup teams?

America’s Cup teams rely on a vast network of infrastructure and facilities to design, build, test and maintain their yachts, as well as prepare and mobilize their operations for the racing events. Key elements include:

  • Team bases – On-shore facilities housing operations, design offices, workshops and simulators.
  • Boatyards – Climate-controlled buildings for construction and repairs of the yachts and hydrofoils.
  • Shore crews – Staff handling operations, logistics, hospitality, media and other shore-side functions.
  • Design and simulation – CFD software, wind tunnels, and modeling tools to optimize yacht performance before building.
  • Testing areas – Protected open water racing venues to test innovations in real sailing conditions.
  • Specialised equipment – Cranes, custom chase boats, and systems for deploying marks and electronics on the race course area.

The team bases also house control rooms where teams can monitor racing data and environmental conditions in real time when racing yachts remotely. State-of-the-art communication systems transmit telemetry data between the yachts and bases during testing and racing.

What does it cost to mount an America’s Cup campaign?

Mounting an America’s Cup campaign requires a substantial investment, typically funded by private sponsors and the challenging yacht clubs. The budgets for competitive teams generally fall in the range of $80-120+ million. This covers designing, building and testing up to 2 AC75 yachts, the logistical infrastructure, technology R&D, as well as 2+ years operating costs.

Major line items include:

Yacht build costs $12-15 million each
Team base setup $10-15 million
Payroll $5-8 million
R&D and testing $10-15 million
Operations and travel $15-20 million

The defender Team New Zealand reportedly spent over $120 million on their successful defense in 2021. This underscores how competitive technology and team strength requires heavy investment. Teams leverage sponsors from private companies and national groups to fund these campaigns in exchange for branding and hospitality rights.

How can technology race be balanced with affordability?

Balancing technology innovation with cost control and fairness is an ongoing challenge for the America’s Cup protocol. Unrestrained spending on technology risks pricing out smaller teams. Measures to foster affordability and close racing include:

  • Limits on R&D periods, testing days, and yacht quantities allowable.
  • Constraints on yacht design parameters, materials, and construction methods.
  • Shared design concepts and a standard one-design monohull platform.
  • Common components supplied by contracted vendors.
  • Increased reliability and durability specifications to reduce running costs.
  • Standard sensors and telemetry systems across all teams.

However, striking the ideal balance remains difficult. Defenders want sufficient freedom to leverage their resources and push boundaries. Newer challengers aim to close the gap. Keeping costs realistic could allow more diverse teams to mount competitive campaigns.

How is sailing talent scouted and developed for America’s Cup teams?

America’s Cup teams scour the competitive sailing world to recruit elite talent into their crews. Key talent sources include:

  • Olympic sailing classes like the 49er skiffs, Nacra 17 or Finn class with comparable high-performance boats.
  • Experienced America’s Cup and SailGP veterans who bring proven skills.
  • Highly ranked sailors in offshore ocean racing circuits.
  • Collegiate and youth match racing championships highlighting future prospects.
  • Extreme sailing series events and regattas with foiling catamarans.

Athlete development programs within America’s Cup teams also identify and train young sailing prospects from their country over multiple years. Fitness, teamwork and racing skills are developed using training boats, simulators and coaching. This cultivation of domestic talent aims to boost experience levels for future Cup campaigns.


America’s Cup racing represents the pinnacle of technology and skill within the sport of sailing. It began from humble origins 170 years ago and now captivates millions worldwide as sailing teams push the limits of boat design.
