Tidal modelling support for SailGP racing teams

We are developing detailed hydrodynamic models to support the international athletes competing in the 2025 season of the Rolex SailGP Championship


SailGP is an international sail racing Championship, featuring 12 teams going head-to-head on high performance F50 foiling catamarans in short, intense races through 12 events across the globe.

The 2025 season of the Championship is well underway; the world class athletes have competed in Dubai, Auckland, Sydney, Los Angeles and San Francisco, with the sixth event taking place this weekend (7 – 8 June) in New York.

ABPmer is the official Tidal Modelling supplier for SailGP. We are providing race-day current data at 10-minute intervals for key 2025 season races where tides are the primary driver of surface currents, including Auckland, Portsmouth, Andalucía – Cádiz, and this weekend’s race in New York.

Our modelling specialists are creating high-resolution hydrodynamic (water motion) numerical models for the athletes to provide date and time specific maps of current speed and direction across the race areas. The numerical models are developed using a ‘flexible mesh’ approach to allow the accurate representation of locally important bathymetric (water depth) features, while maintaining computational efficiency.

With the SailGP teams racing the cutting-edge F50 wingsailed catamarans to electrifying speeds approaching 100 km/h, tidal current information is a key data-feed used to optimise performance and inform strategy on race days.


ABPmer is a recognised leader in offshore, coastal and estuarine numerical modelling. Our sophisticated numerical models regularly support estuarine, coastal and offshore projects, including feasibility and design studies, impact assessments and operational planning.
