Sorry if I wasn't more concise Luke, what I was curious about, was the use of the entire pages themselves, not just info alone ( unless there are copyright issues), especially seeing the "Restricted" notations on the pages. Can't wait to see the finished product though:up:

I guess that could be done at some point if I really wanted to do it. The "Restricted" text, by the way, just means that during the war it was a classified document and so its use was, as you might guess, restricted to those who really needed it.

Mast heights in the ONI-208-J is not from the top of the mast to the waterline. Its from the top of the mast to the deck. If you take the Zinbu Maru as an example. The ONI states the mast head height to be 82 ft. And the funnel to be 42 ft. But to the waterline those measurements are 91.2 ft. and 63.5 ft. You can check that by looking at the scale under the boat witch is 100 ft. long divided into 25 ft. pieces.

Measure the 100 ft. with a ruler and figure out how many ft. there is pr. ruler division, then measure the mast from top to water and multiply for the correct ft.


I have done that for all merchants in SH-4 that are presented in the ONI and made a small SH-4 ONI manual out of that and combined it with edited ship dat files that contains these values. So you may download that and use the manual from that if wanted.

Yep, you're right. I could've found that out if I had just read the "Instructions for Use" section of the manual (1940s lingo for "Read the Readme!" :D) No worries, though - I can fix it easily enough on my own.

Most wartime accounts of which I am aware place less emphasis using the ONI for assisting with targeting ranges than I think what is being suggested. As far as I understand things, after the action was over the ONI was primarily used to identify the victim of the attack.

Wasn't a simple ballpark estimate used most often for mast height when determining stadiameter ranges?
