Musters and drills.

Musters of the crews at their boat and fire stations, followed by boat and fire drills, respectively, shall be held at least once a week, either in port or at sea. An entry shall be made in the official log book of these drills, or of the reason why they could not be held.

Different groups of boats shall be used in turn at successive boat drills. The drills and inspections shall be so arranged that the crew thoroughly understand and are practiced in the duties they have to perform, and that all the boats and pontoon rafts on the ship with the gear appertaining to them are always ready for immediate use.
