The stand-on vessel initially keeps course and speed. That stable behavior helps the give-way vessel predict the encounter and maneuver safely.

Avoiding action should be positive, made in ample time and large enough to be readily apparent. With sufficient sea room, a substantial course alteration alone can be effective if it is made in good time and does not create another close-quarters situation.

Masthead light 225°, each sidelight 112.5°, and sternlight 135° total—67.5° on each side of dead astern.

First remove harmful slack-tank free surface in a way that also improves trim; only then add additional ballast if needed and safe.

Atmospheric refraction is greatest near the horizon and decreases rapidly as altitude increases; low-altitude sights are therefore more vulnerable to abnormal-refraction error.

First scale the known fuel per mile by the square of the speed ratio, then divide the remaining fuel by the new fuel-per-mile value.

Electrical-conductivity measurement is a common basis for marine salinity indication because dissolved ionic salts increase water conductivity.

A hydropneumatic pressure tank uses a compressed-air cushion to maintain pressure and reduce pump cycling. If the tank becomes waterlogged, the pump tends to start and stop in very short, frequent cycles.

A hydraulic accumulator stores potential energy by retaining hydraulic fluid under pressure, allowing short-duration flow or force when the pump is unloaded or stopped.

Increasing DC field excitation strengthens the rotor magnetic field and increases hold-in torque, subject to machine limits.

Student: What is the stand-on vessel’s initial duty?
Example stored-knowledge response: The stand-on vessel initially keeps course and speed. That stable behavior helps the give-way vessel predict the encounter and maneuver safely.
