QtVlm create a POI

De VlmWiki

In Real Boat Management Mode, you may establish your own way points and routes and use them in you other navigation tools manually, or transfer them into OpenCpn for appropriate use with your real boat.

In Virtual Race Mode, you may establish your own way point(s) or POI and send it to the AutoPilot. The waypoint items below apply to Virtual Race mode:

If no value has been filled, your Way point (WP) is the next mark, provided (lat,lon) are entered as '0'. When you fill a value (lat, lon) in the 2 WP text boxes, the next race mark is forgotten until you reach your waypoint.

  • A WP is considered as 'reached in VLM when the distance between the boat and the WP is less or equal to the distance the boat sailed during the previous crank (vacation). So in fact the WP is always reached *before* the boat hits it.
  • After a WP is reached, what happens depends on how the WP has been set-up:
    • If there is a "Heading-to-follow-after-WP", then the boat will be set in heading mode with this value. Nice, but if the wind happens to come from that direction, you might not move a lot...
    • If there is no such value defined in the WP (i.e. it has been set to "-1"), then the boat will keep the same navigation mode (VBVMG, VMG or ORTHO) as the one it had before reaching the WP, using that mode toward the closest point of the next race gate. Nice again, but if there is land between the boat and the next gate that might create problems..
    • By default qtVlm will set "heading-to-follow" with the last direction that the boat was sailing when the WP was reached and deactivated.
