ECDIS manufacturers are integrating more and more decision assistance tools into ECDIS to increase the possibilities their system offers.
For years the Man over Board function has been the only tool of that type but now it is accompanied by other decision assistance tools.
The following examples provide a first view on such new features.
An important tool is the "Man over Board" functionality. ok, some people might say "Person over Board". I am old, I prefer to old way.
Anyhow, depending on the SAR situation the OOW needs to decide between different search methods. Three of those are described with ECDIS relevant details and an associated diagram below.
Each method requires different parameters. The system will not generate a search method proposal if the parameters value is not in line with his respective ship's maneouvre parameter.

There has been a long standing desire to provide collision warning or an alarm of a potential close quarters situation.
The new tool automatically analyses all RADAR and AIS visible targets and provides advice to avoid the danger. These could include change of course, or visual or sound signals to other ships.
The "Course To Steer" proposal is based on analysis of the position, course and speed of all ships in close proximity and computes CPA and TCPA with own ship. Dangerous or risky courses are indicated in red on the displayed pop-up, safe courses in blue.
The specified own ship's parameter can be changed either by the OOW or exclusively by the master.
The OOW can change inter alia:
The master can change inter alia:
The calculation is made on default values if no change is made.

Piracy activities are displayed graphically by this tool. The information is updated daily. Piracy information is combined with current weather information to allow the ship's crew to plan a route with the lowest risk of piracy attacks.
This tool underlines the options ECDIS offers. Information provided from different sources is collected and analyzed to offer important decision assistance.
