Executive Summary
Traditional sailboat racing relies on human race officers to judge starts by eye, a method often limited by blind spots that lead to decisions that are difficult to verify. Vakaros, a leader in marine technology, has developed RaceSense: a cutting-edge race management system that digitizes the entire racecourse. By integrating Swift Navigation’s Skylark Precise Positioning Service, Vakaros provides the centimeter-level accuracy needed to track boat positions in real-time, automate officiating, and provide performance analytics to sailors worldwide.
The Challenge: Visibility and Verification on the Water
Sailing takes place in a dynamic, high-stakes environment where traditional officiating and coaching face significant hurdles:
- The Starting Line Blind Spot: On starting lines that can be over a mile long, it is physically impossible for a human to see every boat. This leads to general recalls (restarts that can waste hours of competition time) when race officials cannot confirm if a boat crossed the start line too early.
- Subjective Rule Enforcement: Rules in sailing are complex. Disputes often end up in a protest room, where outcomes depend on the unreliable memories of the participants.
- Learning Curves: Unlike sports in controlled environments, sailors have historically lacked the data to understand why one boat was faster than another in specific wind conditions.
- Infrastructure Barriers: Setting up physical RTK base stations in remote coastal areas is logistically difficult for the non-technical volunteers who often run these events.
The Solution: A Digitized Racecourse with Skylark
Vakaros built the RaceSense ecosystem to move sailing into an era of indisputable, data-driven officiating and performance review. Every boat is equipped with a Vakaros device (such as the Atlas 2 or the RTK-enabled HALO), which serves as the boat’s primary instrument and data hub.
How it Works:
- Cloud-Based Precision: Vakaros leverages Skylark corrections to achieve centimeter-level precision, without the need for local base stations.
- Advanced Hull Mapping: The system combines high-precision positioning with orientation data to map the shape of the hull. This captures a record of where the front of the hull is in real time, rather than just the location of the instrumentation.
- Proprietary Mesh Networking: Vakaros uses a specialized mesh network to distribute these corrections across the water, ensuring every device stays synced even in areas with spotty connectivity.
"A reliable and adaptive way of providing corrections is critical to the success of our product. With Skylark, we have the precision to know immediately and accurately if a boat crosses the start line early. Nothing’s more frustrating for sailors than having to restart races over and over, so they absolutely love the certainty we provide.”
Key Benefits
The reliable positioning data provided by Skylark enables a suite of features that span the entire duration of a regatta.
1. Automated Race Management
RaceSense eliminates the guesswork of the start. Because the system knows the location of every boat and the line coordinates to within centimeters, it can instantly identify early starters. This ensures a fair start for every boat, from small dinghies to 100-foot yachts, and allows organizers to get races off on time.
2. Digital Officiating and the Virtual Protest Room
Vakaros is moving the sport toward on-the-water umpiring. By recording the exact position and attitude (pitch and heel) of every vessel, the technology turns subjective maneuvers into recorded facts. This reduces the time spent in litigation after the race, as the data provides a clear, objective truth of who was where and what they were doing.
3. High-Resolution Tracking and Replays
Much like a watt meter in cycling or telemetry in Formula One, Vakaros provides a full digital replay of the race. Sailors can review their tracks to see:
- Tactical Analysis: How they responded to wind shifts compared to the leaders.
- Performance Metrics: How boat speed was affected by specific changes in pitch or side-to-side heel.
- The Learning Curve: New sailors can digest facts rather than opinions, helping them close the gap with professional teams more quickly.
4. Operational Efficiency and Sustainability
By digitizing the marks and the line, race committees can reduce the number of staff and support powerboats required on the water. This lowers the operational cost of the event and reduces the carbon footprint associated with race management.
Results & Value Proposition
Vakaros RaceSense, powered by Skylark, has transformed the racing experience for over 500 events annually.
Global Scalability: Operating in over 40 countries, Vakaros relies on Skylark’s expansive coverage to ensure their products work wherever the wind blows.
Elite Precision: The system is currently being positioned for use in upcoming elite international events, where the difference between a gold medal and fourth place is often measured in centimeters.
Amateur and Pro Appeal: From amateur sailors who want to maximize their weekend time to professional teams with off-site data analysts, the solution provides value across the entire market.
