Sailing performance & race preparation
I help boat owners and coaches review race data and prepare for upcoming events.
The work includes race debriefs, performance analysis and polar development, as well as weather routing and crew briefs for offshore races.
Offshore routing
Compare forecasts and routes for an offshore passage, then take the plan aboard with Offwind.
Windward–leeward analytics
Find the seconds
between the marks.
Speed through the tack. Time to accelerate. The gain from a better shift.
