You do that by comparing the standard aspect ratio to the presented aspect ratio.
Standard Aspect Ratio (now SAR) is the ships length divided with the ships height from waterline to masttop.
So with the Mogami its SAR is 656/113,5 = 5,779=5,8
Presented Aspect Ratio (now PAR) is the ships length in periscope tics divided by the height in the periscope in tics.
now to find the AOB you multiply PAR with 100 and then divide with SAR
PAR x 100
--------- = Variation in %
SAR
Now you bring out your Angle on the bow aspect scale rule and find the AOB from the variation - or - you bring out a sinus scale and look the percentage up. |
Methinks this guy has done this for real.
