Three Lengths

Race

A fleet sailed round a real course by the same engine that draws every hearing: the same polar, the same tacking losses, the same marks left on the same side. An umpire calls the rules as they happen. Each boat’s tactician decides when to tack, which end of the line to start at and when to play a shift. The helm does the rest.

The same seed lays the same line and blows the same breeze.
The fleet
  • Steady: Middle of the line, laylines, no gambles.
  • Shifty: Plays every shift: tacks on headers, gybes on lifts.
  • Cover: Wins the favoured end, then covers the fleet.
