Damage Control Priority
Repair parties deploy automatically. The selected priority gets most of the available repair capacity.
Transit — skip the empty water
Fixed runs stop at their stated end or sooner for a tactically meaningful contact,
aircraft, new actionable signal, damage, shoal water or waypoint. “Until” has no time ceiling and uses
the same safety interrupts. Routine updates remain in the radio log without repeatedly stopping the boat.
