ORCi offshore races: courses and starts

ORCi (ORC International) is the rule of the Offshore Racing Congress, the world body for offshore racing rating rules. A velocity prediction program (VPP) works out each boat's expected speed from its measurements for every wind strength and angle, then corrects its elapsed time. It is used alongside IRC at the Rolex Sydney Hobart and the Rolex Middle Sea Race.
