When is the Church Pennant typically flown?

The Church Pennant is traditionally flown during church services aboard a vessel. This practice reflects the religious observance and shows that a worship service is taking place on the ship. The pennant serves not only as a signal to those on the vessel but also to other vessels nearby that a religious event is occurring, promoting respect and maintaining a sense of decorum surrounding the occasion. It represents spiritual functions and underscores the ship's commitment to honoring its crew members' faith and practices while at sea.
