OCEAN RACING AT THE CUTTING EDGE
Modern ocean racing sailing boats are high performance machines, almost more comparable to aircraft than the yachts of old. They combine cutting edge material science, aero and hydrodynamics, navigation systems, telecommunications, and sensors.
IOT data for performance optimisation and intelligent automation
Modern racing boats have fully integrated internet of things (IoT) with sensors ranging from wind speed and direction, to load meters, autopilot actuator sensors, accelerometers, GPS, echo sounders (depth), water logs (speed through water), and more. This generates a large and diverse set of data.
One underdeveloped technological domain is the use of real-time data from boat sensors for automated performance optimisation. While data is relayed via displays to a human, there is little or no interfacing with the autopilots that are vital for long distance racing with only one or two crew.
The performance gap
Autopilots for sailing boats are comparatively crude. They are responsible for >95% of steering on single handed sailing races. However, they only achieve 80% of the performance of a human. Statistically just a 2% performance increase on the previous edition is all that is required to win the Vendee Globe.
There is an enormous potential to provide a race winning advantage through the development of machine learning driven AI for these autopilots.
A high performance test platform: Concise 8, Class 40
Concise 8 was developed in 2013 as a third generation Class 40. Designed at the cutting edge of technology utilising techniques developed during America’s cup, Volvo Ocean Race and IMOCA 60 campaigns, she is a sleek, high-speed, state of the art machine.
Dimensions – 12.19m long, 4.5m wide, 3m deep and 19m tall
Weight – 4500kg all up, with over 2000kg in the keel
Sail Area – With upwind sail area limited to 115m2, Concise 8 sports a massive 250m2 downwind
Whilst newer boats have been launched since the inception of Concise 8, few have demonstrated the speed and capability of her radical design, so she still remains a strong favourite in all races she enters.
Working alongside Jack Trigger Racing and control and sensor systems manufacturer NKE, we are harvesting highly granular IoT sensor data directly from the boat’s processor.
the human sailor, jack trigger
Jack is the rising star of british offshore sailing. He is ultimately driven to compete in the Vendee Globe and challenge to become the next successful British skipper in the race. His dream is to follow in the footsteps of Dame Ellen McArthur and Alex Thompson, and even to go one better than Alex who came second in the last edition.
Competing in the Class 40 division with maximum support and achieving good results in the championship and Route du Rhum are a major step towards achieving this.

With an engineering background from Oxford, he is the ideal sailor to work with us on the development of an intelligent autopilot solution. He is also a type 1 diabetic, a condition that is problematic for an extreme sportsman. Admirably, Jack is at the forefront of a technological push to help manage the condition, as well as being a role model for young people that share it with him.
The Everest of the Seas
The Vendee Globe is the only sailing race around the world, non-stop, and without assistance. Known as the ‘Everest of the Seas’, only 167 competitors have taken part, with 89 completing the race and 6 winners.
While competing, the sailors are more isolated than astronauts on the ISS, both in terms of distance from land, solitude, and support (they have none). Connection to the outside world is only via satellite link.
Formula One of the Oceans
The modern boats for this race are truly at the cutting edge. Built of lightweight carbon fibre, and now with hydrofoils, they are punishing to race for the human sailor as they travel across the sea at up to 65 kilometres per hour. It is in this context that autopilots are used to steer the boat the vast majority of the time (up to 95%), while the human sailor adjusts the sails, navigates, and manages the system as a whole. The sailors only sleep 20 minutes at a time for over 70 days.
It is into this environment that we want to place AI, test it at the extreme, and provide a race winning edge.
A Technology Team Up to the challenge
The project involves a number of partners from across academia and industry: Jack Trigger Racing, Microsoft, Imperial College London Aeronautics division, and WisCont. In collaboration with our partners, T-DAB is aiming to develop cutting edge machine learning driven artificial intelligence to deploy to standard, off the shelf autopilot hardware.
Combining ML/AI, IOT and Edge computing
powered by Microsoft
The project provides an ideal opportunity to test, develop, and show case the use of the latest machine learning, IOT, edge computing and Cloud solution technologies.
In particular, the team plan to use Microsoft technologies that allow for training of algorithms in the cloud, streaming of data from remote connections, and deployment of algorithms to remote, low power computing hardware.
IOT data for performance optimisation and intelligent automation
To bring more intelligent automation and control to marine autopilots, we are developing, testing, validating and benchmarking a number of machine learning models. These include both deep reinforcement learning and advanced recurrent neural networks (RNNs).
In order to do this effectively for the amount of data required, we a supported and powered by Microsoft and their cloud based Azure Databricks solution (hyperlink). Azure Databricks is optimised for deep learning, supports multiple languages and libraries, integrates with other Azure services, and provides an ideal collaborative working space.
AI at the Edge, powered by Microsoft Azure IoT Edge
Ocean racing sailing boats are extreme environments for technology. They are isolated, connected only by satellite links with limited and expensive bandwidth. In addition, power onboard is at a premium with the priority being weight reduction for speed. This means that computing power is limited, presenting a challenge for the deployment of machine learning algorithms. Nor can they be connected continuously to the cloud.
Microsoft Azure IoT Edge provides the ideal solution to solve this problem. It allows for the storage of data and development and training of machine learning algorithms in the Azure cloud, while then optimising the deployment of these algorithms to remote, low power computing as close as possible to the point of action.
There is no more suited use case for this technology than a sailing boat in the middle of the Southern Ocean!
