Autopilots
- Autopilots are electronic systems that, when working well, are capable of maintaining a given course provided there is ample forward propulsion
- Autopilots are used to maintain a steady course on a given heading and are particularly useful during long periods of travel where the course isn’t expected to change
- Autopilots do NOT relieve the burden of maintaining a vigilant lookout and ensuring that the course ahead remains free from vessel traffic, debris, and that the autopilot continues to set the ship along the intended heading
- Because autopilot systems rely on rudder alterations to steer the ship, it should be remembered that rudders (and therefore autopilots) are less effective at slower speeds
- Because the transition between manual and autopilot steering has the capacity to produce a hard over turn (as mistakes and equipment failure can occur), change over from manual to autopilot should always be monitored by the OOW and take place in a area free from nearby vessel traffic and navigational hazards
- After autopilots have been engaged, they are to be monitored to ensure they are in fact working as intended and making rudder adjustments appropriately
- During this time of monitoring the autopilot after it has been engaged, the helmsman is still on duty and may be stood down once the OOW deems it appropriate
