This is the email I received from Marine Traffic on their upgrade this morning. Maybe this will help:
Dear Sir,
MarineTraffic started back in 2007 as a pet project and has since grown to be the most popular vessel tracking service in the world, regularly used by the whole maritime community.
Through the years, we have listened to your comments and requests and tried hard to continuously improve the service and expand our global coverage. We are more committed than ever to continue making MarineTraffic more useful, reliable and relevant to your needs.
During the past few months we have been rebuilding the website and the mobile applications, including a full redesign, more data and several new features.
While keeping the existing service free, we are introducing a number of paid plans, built for users that need to make intensive use of the system resources and wish to access the value-added services, such as:
Satellite AIS data for global AIS coverage, including mid-ocean vessel tracking. Available with the SAT or SAT PRO Plans.
Detailed, global
Nautical Charts for in-depth insight and situational awareness. Available with the PRO Plan or higher.
Export data to CSV files directly from the website. Export limits according to respective Plan.
Use MarineTraffic
API data services to feed data directly into your applications. Available on request.
Retrieve
historical AIS data within the billions of position records archived from 2009 onwards. Available on request.
Also, extended fleet management and notifications are made available for professional users, for intensive use of email and SMS alerting services. We will continue adding more features and tools for you, whether you are a maritime professional, a ship enthusiast or just need to follow a vessel!
Some of the premium services will be offered to our contributors (AIS station operators and Photographers) for free. In the effort to expand our coverage, we are always reaching out to new AIS station operators who now have one more strong incentive to join us.
Note that we have already started a gradual rollout of the new website, which will reach all our users soon. We would like to apologise in advance for any temporary instability issues you might experience during the migration
