The best part is that it's free! It has all features I need for my business, including tracking vessels in multiple ways (AIMD/VTS). Easy navigation through menus makes this software easy-to use even without prior experience with navigational tools or databases like MMSI numbers etc., which are not available within its interface but can be obtained from external websites via API integration - great idea!! Not much as such; just keep using what you have now until they add more functions at no additional cost :) Good way track your vessel movements online so everyone knows where exactly their boat will go next time around :)).
