Inside the build
Sailing physics and multiplayer.
Context
Wind angle affects thrust, while the multiplayer service keeps players in the same sea.
How it works
Point of sail and heading determine thrust and speed toward a mark. The HUD shows relative wind, heel and velocity while you sail.
In the work
Live at saltline.app with accounts, persistent cargo and up to 20 players per sea.
