I actually got my first kill the other day useing the DO method! RR great tutorial by the way

I got a radar contact at 10nm. I slowed to 1/3 speed and began my first plot. Three minutes later I took another reading and plotted. After determining his course, I got in position 90 degrees to his track and set up the TDC as per the tutorial.

The one thing I have a problem with is getting an acurate speed, which is essential with this method. Since the Radar screen dosn't have range rings, it's hard to determine exact distance between the two plot points, so therefor measuring the distance between the two points will yeild an inaccurate figure. I actually find it a challange to aquire a visual, get an ID, and measure the time it takes for the target to cross the 0 bearing line to determine speed.

Anyway, after I did all that, (target was a Hog Islander by the way) I sat and waited for the target to cross my 10 degree bearing line. I fired three shots: One at the forward crane, one under the stack, and the last at the aft crane. All three shots impacted, but my speed must have been off a hair because the shots hit further aft of their intended AP. She went down about 20 minutes later after slowly flooding

It seems to me, once you have an accurate speed, the rest is sinfully easy!
