Costamare Shipping CO S.A., ordered four additional Admiral ECS for its Maersk Tokyo, Maersk Toba and 2 other vessels. This is the second time Costamare has purchased the Admiral system for its ships. In December 2006 the company ordered three for the MSC Sicily, MSC Tuscany and Sophia Britannia. Admiral ECS (Electronic Chart System) is installed in 140 vessels globally, ranging from 300,000 ton supertankers to 515 foot superyachts. More user friendly than most ECDIS installations, Admiral uses plain English menus rather than icons for its user interface. For this reason, some ECDIS equipped vessels also have an Admiral installed. The C-MAP vector chart database, using the Real Time Update Service (RTU), is updated automatically by the Admiral software.
