GPS Tracking Allows Better Managed Yacht Delivery

By Alexander Hunt


GPS technology now makes yacht delivery a simpler and much safer task. The technology allows the location of a vessel to be monitored continuously by shore-based managers ready to raise an alert if necessary. Vessel tracking devices are a valuable tool for both mariners and land-based managers. Various configurations are used but they all are inexpensive, simple and allow registered users to view the vessel location on a convenient, computer-based map.

Some marine tracking devices use the mobile phone network (GSM) to communicate their location. Others transmit to a satellite allowing coverage in areas where the mobile phone network does not cover. Tracking devices dependent on mobile phone networks are suitable for vessel tracking along coastal voyages. However, they will not allow the tracking device to communicate when a vessel is in the middle of an ocean. Satellite based tracking systems allow position to be monitored virtually anywhere on the globe.

Some of the tracking devices operate on power from the electrical system of the vessel. Others operate from a battery power supply (4 standard AA size lithium batteries) that will operate for one to two months, based on the device communicating its position 12 times per day. Battery life can be extended by reducing the number of transmissions. For example, battery life can be prolonged to one year if tracking transmissions are reduced to one a day.

Satellite-based tracking can be configured in several ways.One approach is to integrate the system with the INMARSAT C communication capability of a vessel. Alternatively, it can involve the installation of a compact D+ transceiver. These units are so small that they can be installed, or buried, discreetly within the hull or deck fittings. The D+ transceivers generally require either 12 or 24 volt electricity supplied from the electrical system of the vessel.

The transceiver is the only physical component that needs to be installed on the vessel. Its dimensions are small, about 3 cms high, 10 cms wide and 15 cms long. The transceiver contains a GPS transmitter and software to allow bi-directional communications with the INMARSAT satellite constellation.

Some systems allow owner-defined security alerts to be set-up and transmitted in real time to the owner via email and mobile phone. For example, the owner can define a geofence around a control area within which the yacht is expected to operate. If the yacht is reported outside that area, an automatic message is sent to the vessel owner.

In conclusion, various risks associated with yacht delivery and general as well as general travel at sea can be more closely managed with GPS tracking devices. These clever little units are a logical extension of GPS technology. Many mariners believe their cost represent good value given the improved risk management they allow.
