There are only three rules that decide who gives way under sail - but they're not the kind of thing you can look up in the half-second before two boats close the gap.
I couldn't reliably remember them, so I built a way to drill them until I could. No account, no clutter - open it, get a scenario, answer it, see why.

Two boats, different tacks, courses cutting through each other. Port always gives way to starboard.
Same tack, closing in from behind or alongside. Whoever's further upwind gives way.
Coming up from clear astern. The overtaking boat gives way - tack doesn't matter.
Know the rules. Nail the calls.
