Laylines use the 47.7 polar + your wind (and tide, if set). Only as good as your masthead read; a running tide moves the real layline. Glance, don’t stare.

Start tips
Ping the line ends & start the sequence for live coaching.
📡 Light up the fleet
These tools are free — and they get better the more boats are on the map.
You’re out on the water anyway: share your track and your fleet appears live for everyone,
replays fill in on their own, and you get the live map back in return. It’s give-to-get, no charge.
