Race
Manually cut the race off at a finish time — anything logged after it is ignored for both boats, everywhere below.
The finish time here can only cut the race shorter — there are no original files on this page to extend it from. In an event, the finish time everyone shares is set on the event page; this one changes what you see here.
Summary
Wind
Both boats always use the same wind — recorded wind is preferred over an estimate, and if only one file has a recorded reading, that's used for both. Applying it here (or overriding it manually) recomputes VMG, tack/gybe detection, wind-angle legs and the polar overlay for both boats at once.
The wind through the race
Track comparison
Includes the start line (from each instrument's logged pin/boat-end position, averaged if both have one) so the approach to the start is visible alongside the rest of the track.
Speed & VMG
Start analysis
Each boat's position relative to the start line at the gun, and how it crossed it — based on the start line position logged by each instrument.
Start line bias
Wind-up view of the (averaged) start line — which end was favoured, and how much of that advantage each boat actually used from where it started.
Race sequence
Every leg, its straight-line-only equivalent (manoeuvres filtered out of the numbers), and the mark rounding into the next leg — in race order. Legs are matched between boats by the most overlapping race time; a mark rounding only appears where both boats have a clean, contiguous leg boundary to measure it from.
Manoeuvre efficiency
Tack analysis
Each boat's best (highest made-good) tack of the race, compared head to head.
Gybe analysis
Each boat's best (highest made-good) gybe of the race, compared head to head.
