Global current information and competitive sailing

Published: 9 August 2017

The difference between winning and losing an ocean race is sometimes just a matter of minutes. Early in the morning of 9 August, the Rolex Fastnet Race, part of Leg Zero of the 2017/2018 Volvo Ocean Race finished after almost 2 days and 16 hours at sea. Only 14 minutes separated the top 4 teams, with the Dutch teams Brunel and AkzoNobel finishing 3rd and 4th.

The need for reliable information about tidal and deep-sea currents is of vital importance to race competitors. Between Cowes (Isle of Wight), Fastnet Rock (southwest Ireland) and back to Plymouth, the sailing boats entering this race have to deal with both tidal currents and with storms from the Irish Sea and the Northeast Atlantic. Feedback from these races is important to support Deltares’ on-going research related to global modelling.
