Man Over Board
|
An Alternative MOB Approach.
For the use of emergency AIS-SART, go to this page. |
Drop a Man Over Board Marker at your present position by pressing
* Man Over Board Button
on the ToolBar or hit the Keys
*Ctrl + Spacebar.
A mark, looking like the button is instantly created - the MOB mark.
The MOB mark will be called "MAN OVERBOARD at + time-stamp"
A temporary route, from a point 1 mile ahead on the current COG, and to the MOB mark is created and activated. On the screen, a course and bearing to the MOB mark will be displayed. This temporary triangular mark is labeled "1.0 NM along COG".
If COG, course over ground, is not available, no route is created but the MOB position is marked. This can happen if no GPS is connected, if the GPS signal is (temporary) unavailable or if the speed is so low that the GPS doesn't calculate COG.
To delete a MOB
The temporary route can be deleted, through the right-click menu, but no action of the user with the mouse or keyboard will move or delete the MOB mark, except for a right click -> Mark/Wpt Properties and select a different icon, and then delete the mark (ex mob mark) from the right click menu, or through the Route Manager.
Multiple MOB marks can be deployed, and multiple temporary routes will be created. The active route will always be associated with the last dropped MOB mark.
Be very careful when using this capability in waters with strong tide or current.
The person overboard will not be at the position of the MOB mark for long. Both Own Boat and the person in the water will move with the current, but OpenCPN knows nothing about this.
The MOB mark has just been dropped
Own Boat has moved on and the MOB bark is 0.65 miles in bearing 200 degrees.
One option in this situation is to drag the triangle to the Own Boats position.
A second MOB mark is dropped.
