Race Story

Boat Mini Charts

Per-boat synchronized speed, VMG and gap-to-leader traces.

Race Track & Maneuvers

Dashed overlays show start/gate lines and race boundary (updated when they move). ↩ = tack, ↪ = gybe. Boat rhombs use class-length footprints aligned to heading: AC75 about 75 ft long, AC40 about 40 ft long. Use the trail selector to switch between no trail, a short recent trail, a longer recent trail, or the full trace so far. The VMG subplot sits with the slider so you can compare pace over time while scrubbing the replay.
