Autopilot systems on boats are designed to keep vessels on course, even in high winds and strong currents. They can be expensive, but they transform life on board. However, they can be ineffective in light airs and are not suitable for motoring in calm conditions. They can also be dangerous in certain situations, such as when navigating waterways with heavy vessel traffic or known underwater hazards. During rough weather, the electric power needed to operate an autopilot can be high, and sudden energy spikes can cause the unit to fail or generate faulty data.

|---|---|
| Avoiding storms | Autopilots can be used in storms, but the electric power needed to operate an autopilot during rough weather is high and sudden energy spikes can cause the unit to fail or generate faulty data. |
| Cost | Autopilots can be expensive, with below-deck units for larger boats that perform complex functions costing upwards of $3,000. |
| Functionality | Autopilots work much like cruise control on a vehicle, except that manual control of the tiller or steering wheel is not needed. |

Autopilot systems can be expensive, with some costing upwards of $3,000
Autopilot systems can be a great investment for boaters, offering efficiency, convenience, fuel savings and safety. They can keep a boat on course in spite of strong currents or winds, and some systems can even handle storms. However, the electric power needed to operate an autopilot during rough weather and heavy use can be high, and sudden energy spikes can cause the unit to fail or generate faulty data.
There are a number of popular marine autopilot systems on the market, including the Furuno Navpilot 300, Garmin Autopilot Reactor 40, Garmin Autopilot GHP 20 and B&G autopilots. These systems generally consist of three main components: a course computer (or central processing unit) that contains a compass, a drive unit that applies force to move the rudder, and a control unit.
When choosing an autopilot system, it's important to consider the six key elements that make up the system, including the drive unit that moves the rudder, either with a direct connection to the rudder stock or by turning the wheel or tiller. It's also worth noting that windvanes tend not to be effective sailing downwind in light airs or when the apparent wind is low.

Autopilots can be ineffective in light winds, when the apparent wind is low
Autopilots work much like cruise control on a car, except that manual control of the tiller or steering wheel is not needed. After the vessel is steadied on a desired heading for a few seconds, an “Auto” button is pushed and the autopilot takes over. The computer remembers the heading and adjusts the rudder position to keep the vessel on the selected course, even in high winds, strong currents, or over/under steering situations.
However, there are some situations in which an autopilot may be ineffective. For example, in light winds, when the apparent wind is low, windvanes tend not to be effective. This is because the autopilot system relies on wind to function. If there is not enough wind, the autopilot may not be able to keep the boat on course. In these conditions, it is recommended to use an electronic autopilot instead.
Additionally, the electric power needed to operate an autopilot during rough weather and heavy use can be high, and sudden energy spikes can cause the unit to fail or generate faulty data. In some cases, it may be safer to have a manned helm, such as when navigating waterways with heavy vessel traffic, known underwater hazards, or shallow water.
Overall, while autopilots can be a useful tool for boat navigation, they may not always be effective in light wind conditions or during extended periods of rough weather. It is important for boat operators to understand the limitations of their autopilot system and be prepared to take manual control when necessary.

Autopilots can be dangerous in some conditions, such as in areas with heavy vessel traffic or known underwater hazards
In addition, the upfront cost of an autopilot system can be relatively expensive, and windvanes tend not to be effective in light airs or when motoring in a calm. They are also useless for sailing downwind in light airs, as the apparent wind is low and from ahead, irrespective of your course.
Even for short periods, an unattended helm without an engaged autopilot can put the boat off course and create potentially dangerous or unsafe situations. This is because different combinations of wind and waves will repeatedly knock a boat off course. Therefore, it is important to understand the six key elements of an autopilot system before choosing one, including the drive unit that moves the rudder and the control unit.
Overall, while autopilots can be helpful in some situations, they should not be relied upon exclusively and manual control may still be necessary in certain conditions.

Autopilots can fail or generate faulty data due to sudden energy spikes during rough weather
Autopilots work much like cruise control on a vehicle, except that manual control of the tiller or steering wheel is not needed.

The computer remembers the heading and adjusts the rudder position to keep the vessel on the selected course, even in high winds, strong currents, or over/under steering situations.
However, different combinations of wind and waves will repeatedly knock a boat off course. This means there's a lot more that goes into autopilots, both in terms of how they work and how to pick the most suitable components for a specific boat. For example, an electric autopilot may struggle to handle storms that last for several days.

However, it's important to note that different combinations of wind and waves will repeatedly knock a boat off course. This means there's a lot more that goes into autopilots than just maintaining a straight course. For example, the upfront cost can be relatively expensive, and windvanes tend not to be effective when sailing downwind in light airs or when motoring in a calm. Additionally, the electric power needed to operate an autopilot during rough weather and heavy use can be high, and sudden energy spikes can cause the unit to fail or generate faulty data.
In some conditions, navigating a vessel with an engaged autopilot can create potentially dangerous situations. For example, if underway on waterways with heavy vessel traffic, known underwater hazards, shallow water, or areas where crab pots are deployed, the helm should be manned.
