Name the following maneuvers number 17 number 19 number 22 and number 27.

• A. Number 17 propeller reverse; number 19 pairs alternate left and right at the rail; number 22 line; number 27 left and right to center
• B. Number 17 propeller reverse; number 19 pairs alternate left and right at the rail; number 22 line; number 27 center line
• C. Number 17 propeller reverse; number 19 line; number 22 line; number 27 left and right to center
• D. Number 17 propeller reverse; number 19 pairs alternate left and right at the rail; number 22 line; number 27 left and right away from center

Answer: (A)

In drill and formation terms, each numbered maneuver corresponds to a precise action: propeller reverse means backing the vessel with reversed propulsion; pairs alternating left and right at the rail describes two-person units alternating sides along the rail; line indicates forming a straight line; left and right to center means the crew moves from both sides toward the centerline to form a symmetric arrangement.

The best match pairs propeller reverse with the first maneuver, alternating pairs at the rail with the second, forming a line with the third, and moving left and right toward the center with the fourth. This last one ensures a symmetric setup around the centerline rather than placing everyone on the center line or moving away from center, which would disrupt the intended formation.
