Marine autopilot systems are already in existence, but there's a glaring issue with existing options. While it is true that these systems can be used to give the boat captain a rest, they are designed to react to changes in conditions after they occur. This can be too late in certain circumstances where you'd prefer that the system preempt threats and take a proactive approach to keep danger at bay and keep the boat's occupants safe.
This system is capable of automatically adjusting its course, even though the captain can overrule it at anytime. It can also guide boats from port to port using the safest and most efficient route.
This marine autopilot system is still in its testing stage, but it is bringing a long overdue technology upgrade to the marine vehicle world.
