  • “The tactical tool „CurrentNow“ for measuring sea currents provided me and my coach with the right information at the right time for winning various medals at the Paralympics and World Championships over the last years.”

Even 0.1 kn difference in current between left and right side on a typical race course gives a typical advantage of 50-100 m at the top mark.
Some race areas have half-hourly changes of current speed of more than 0.5 kn and in direction of more than 20 degrees. The maximum current can be up to 6 kn.
The system:
CurrentNow is a highly accurate sensor-based sea current measurement system which has been used worldwide for almost a decade in offshore racing and Olympic racing. Many thousand working hours have been done and many thousand measurements being made. CurrentNow has proven to measure current direction and speed with an accuracy of 1 degree and 0.1kn, respectively.

The system is based on a less than 1kg light drifting buoy with a range of sensors. CurrentNow is coupled by wireless connection to a portable computer or a special handset on a boat.
Use cases:

Measurements directly before races
Extensive measurements to analyse race areas and provide data for current simulations with up to 10 buoys

Data exchange with all relevant tactical programs, like Expedition
Revolution compared to manual current measurements:

Since no fixed point of reference like a buoy is required the measurements with the CurrentNow system can be taken very quickly in almost all weather conditions. Often measurements take less than one minute. Also with manual measurements the inaccuracies are large, i.e. estimation of the direction by handheld compass and “no tape measure on the water”.
