Hah, I think we've reinvented the wheel...so to speak.

Do the Math
One last item from my corner:
Do the Math. I observe thru the scope a Hakusika Maru: Aspect Ratio 4.6 from the book. Aspect Ratio thru the scope: 4.25 tics high 13 tics long. Do I break out my hh electronic calc ? No, I reach for the SACF/IW: Since the SACF is a cicurlar sliderule (logrithmic) with a sine scale: As you can see, 25.1° falls beneath 4.25, the height of the target ship, so I then rotate the center disk to place the 25.1° mark under 13, dividing 4.24 into 13. The answer is read above the sine of 90° = 3.05, the observed Aspect Ratio. I can now proceed to compare the two AR's to obtain my Angle on the Bow with the SACF. 4.6 : 90° : : 3.05 : 42° Simple and fast EDIT NOTE: Had to goto photobucket, ImageShack is having a bad day.

Brilliant
As I said before, I am using a purpose built ruler that makes it all more intuitive, but you are proving constantly how easy it is also with the MK3 once you get the hang of it. I take it you are also using the aspect ratio idea? Does it work well for you? Cheers

Aspect Ratio concept:
I can honestly say, no, Hitman. I was just using, "a sailor's eye" for obtaining Ab . Your influence with AR and the Side 2 have greatly made these Sims alot more interesting. Outstanding! I look back over the years of playing subsims ... don't know how I was able to sink anything without...doing the math.

Greetings, I'm new to this forum, but I also have to add that the SACF has totally revolutionised my style of play. To think I used to use fast 90 targetting! Now target tracks of 100 or 110 degrees every time.
I've written a tutorial on how to use the wheel to conduct passive sonar only approaches in conditions of poor visibility, rough weather, or when it is otherwise impractical to rely on frequent periscope sightings (obviously a minimum of one sighting is still required before firing). Is there an appropriate place to offer such tutorials? I still play SHiii, but guess what I found when looking down in the bridge of my type VIIC? Right in the middle of the conning tower...if only they'd made it functional thanks |

Just incase, here's my Ol' tutorial for the Front, AOB side: Quote:
The following (hopefully) illustrates Capn Krunches' example: (it appears C (Enemy Vessel) wheel's 0 points to 330 and not 300, is that correct?) BIG Thanks to Igorry for the Clarification on the Bow oriented up (12 o’clock position) and to Hitman for pointing out that the heading was 330 and not 300. I wanted to provide an easy, clear 3D example of how this looks for my Mates on the Forum. Cheers! ----------------- Visual Aids...Yes Nurse Ratchet let me have an extra hour of arts and crafts time. And now for the Players: First-up The USS "Onkel" Stevens Next, "The Enemy" [The Set-up] 1) Sub Heading: 90 2) Target heading: 330 3) Target Bearing: 300 4) Target AOB: 120 1) USS "Onkel" Stevens Heading 090 (align your heading 090 on Wheel B to 180 of wheel A) * Note Submarine examples do not contain the C Wheel for simplicity 2) Our Target Heading 330 (Align the 0 (zero) on Wheel C to Target course 330 of Wheel B) * Note Target examples do not contain the Transparent Periscope Wheel for simplicity 3) TARGET BEARING 300 relative Sir! (Set the inside Arrow of the transparent Periscope Layer "highlighted in Red" to 300 on the A Wheel.) 4) AOB=120 to Port Sir (now look at The Arrow Tip of the Periscope Layer on the A Wheel) * Note: if the C (3rd inner) wheel were included the Tip of the Periscope Arrow wheel would point to 120. This can be seen on the Is-Was image. And as shown on the Is-Was [In Summary] The Photos: 1) Our Sub's Heading: 90 2) Target heading: 330 3) Target Bearing: 300 (the inside Arrow of the transparent Periscope Layer "highlighted in Red" on the A Wheel.) 4) Target AOB = 120 Shown by the Tip of the Periscope Arrow wheel Highlighted in Red Pointing at the C Wheel The Wheels: A Wheel = Azimuth Circle (Our Periscope/Submarine) B Wheel = Compass Rose (True Heading) Transparent Wheel = The Periscope/TBD/Binoculars "bearing" to target C Wheel = Enemy/Target ship Heading Hope this is correct and helpful! Enjoy [Couldn't resist the result!] "BOOOOOOOOM!" Load #3 Torpedo Attack: Here's what you should see after a minute or two into the simulation: Subs' Heading = 000 due north and speed 0 Target heading = 102.674 (let's use 100) Bearing to Target = 325 AOB = 45 (42 if using Target heading of 102-103) Target speed = 9knts * TIP: once in Map view F3 hit backspace to pause the sim. When ready, hit the NumPab + (plus) key to continue. You can check this by drawing a line out from your sub's center with the distance tool on your course to the 8^ 13' N Now draw another line from the target's center until it intersects your course line. Take the Protractor and draw a line from the Intersection point to the Target's bow, now left-click and draw another line to your bow. The Angle on the Bow should = 45 degrees for AOB=45. Enjoy, Cheers!

Flash version of the front side of the IS-WAS wheel
Hello there everyone,
Instead of going cardboard and paperwise, I went to flash and made the front part of your wheel. Thanks to Captain Krunches pdf files, I came up with this online version. Flash player required http://img456.imageshack.us/my.php?i...swf&width=1024 Does anyone have good photos of the german version of the whizz wheel ? I would like to model that in flash, but can't find any good pictures.
