Module 03
Flags and pennants
A hoist is read from the top down. Flown alone, most alphabet flags carry a standing meaning that an officer of the deck must recognise at a glance — several of them are hazard signals.
Lesson
Reading a hoist
- Single flag: the standing meaning listed below, most of them urgent or navigational.
- Two flags: distress and manoeuvring signals from the international code.
- Three flags: points of the compass, times, bearings and general code groups.
- A substitute repeats an earlier flag of the same class in the same hoist, so a ship never needs two of one flag.
- Hoists are read top down, and the nearest hoist to the observer is read first.
