Plotting course with Just gray lines?

[kylania]

Yes, the end of the sonar sound line is the current position of the ship. So you can just place X's there and plot his course.

If you wanted to do the TMA (Target Motion Analysis) more realistically, try following this HydroHunting tutorial.

As for why your ruler tool is "upside down", you should read my Map Tools tutorial to read why that is and how to properly use it.

In order to find where a 345 bearing from your ship is, use the protractor. Draw the first line from the direction of your travel, or where your boat is pointing, to the middle of your boat the the second line out at a 15 degree angle to port (left) since that would be 360 - 345 = 15. If the target was to your starboard (right) side you'd just drag the second line to 15 degrees. Make sure you zoom all the way in to get it most precise. It's ever easier if you have a bearing overlay loaded, as in the bottom picture here.

Have to say I will def. give this a try as well. Haven't seen the links recently and am excited. The way I was doing it was a hit and miss and although it worked often enough I would rather perfect a realistic approach. Thanks Kyl for that great input.

Yes i second that thank you. I was preatty well sure that the end of the gray line was where the boat was at, But as i said in the real world there not going to have gray lines moving on there map LOL...

So for a more realistic approch i wanted or was looking for something more realistic...All i really needed was to know how to plot useing the upside down thing accuratly...

Now that you have shown me this meathod i will try it...Seems tens times easier to at least get there general direction...TY
