Winston Score History

The full picture

SRT Marine Systems is a British technology company that makes tracking and monitoring systems for boats and ships. Its core product is AIS (Automatic Identification System) technology, which helps vessels broadcast their location so other ships and coast guards can see where they are. The company sells hardware, software, and complete maritime surveillance systems to governments, coast guards, and port authorities around the world.

SRT makes money by selling hardware devices and by delivering large government contracts to build national vessel tracking networks, particularly in developing countries that are upgrading their maritime infrastructure. The company operates globally, with significant project activity in Asia and other emerging markets, and its deep specialization in AIS technology gives it a narrow but defensible position in a niche market. The main risk is that revenue can be lumpy and unpredictable, since the business depends heavily on winning and executing large government contracts, which can be delayed or cancelled.
