Marine AIS was originally developed to allow ships to view marine traffic in their area and to be seen by that traffic, primarily to enhance safety and collision avoidance. However, this flexible technology and the information it provides can now be incorporated into a range of marine AIS transponders, transceivers and other products to offer safety, operational and financial benefits for leisure boat owners, captains, crew, and fishing and commercial vessel operators.
