Since I encounter lots of poor visbility conditions in the North altantic this method worked brilliantly. In fact I started to use it for every contact since I found myself submerge most of the time due to pesky aricraft dropping bombs on me.
Mittelwaechter had a matching video unfortnately the rapidshare link he used no longer works. Wished he would post it up on youtube. |
First you couldn't see it . Now you can!

I'm afraid uploading to youtube isn't as simple. Mittelwaechter used a special compression software that youtube mostlikely doesn't accept. (and it seems to pay of in quality) It's in the form of an .exe. I know, scary wrt virusses and trojans and all. But it's been on my harddrive for a year and AVG never complained about it during scans. Still, download at your own risk.
Also, for the original poster, this post of mine might help: (but DO read further along the thread aswel)

I have created a circular version of the tool but it isn't completely to my taste yet. However I have decided to upload this prototype since I have to live up to the promise somehow.
Filefront description:
Sliderule to compute Angle On Bow (when stationary, if moving Direction of Relative Movement wrt the first bearing) based on 3 bearings only, in 2 equal time intervals. Intended for use with Silenthunter 3 or 4. Inspired by a linear design ("Another Course Computer") on this site:

1. Print out
2. Cut out
3. Don't forget the window on front disk
4. Laminate both disks
5. Make a hinge in the center.
6. Instructions for use are on the front disk.
7. Be patient! It takes time for a good meaningfull AOB value. Forget the 3m(15s)-rule for this thing.
