Two boats meeting at an angle look like port and starboard — how do I know they're not?
Tack is named by which side the boom lies on, not by heading — two boats can point far apart and still be on the same tack. If both booms are out the same side, Rule 10 does not apply; instead Rule 11 governs, and the windward boat (the one nearer the wind, not the one ahead) must keep clear of the leeward boat. Rule 14 still requires the right-of-way boat to avoid contact once it's clear the other boat won't keep clear.
