Wish rec manual had length

[Tonnage_Ace]

I used to get speed in SHIII by putting the length of the ship and time it took for the ship to pass my vertical reticule to get the speed but the length of ships isn't listed in the rec manual. The speed function doesn't seem to do anything for me(it doesn't go above 0). The TDC in general is pretty lackluster in that I can't manually set the gyro, for say, firing at multiple targets in a convoy if I'm 90 degrees off their course. Hope some kind of TDC similiar to SHIII is included in a future patch...

Hi Tonnage_Ace.

I don't have the game yet, expecting it in the mail tomorrow...

Suggestion: If you're given the masthead height (MHH), you might try a ratio/proportion solution to jury-rig LOA, using the tick marks on the vert/hori reticules.

btw: your method of determining target speed is one of my favorites also.

Cheers,

Yea someone else made a table to do just what youre asking for,

lookie here! http://www.subsim.com/radioroom/showthread.php?t=108454

BTW why would you want a TDC like in SH3? Us and German TDCs were pretty different...I think you can shoot at multiple targets look up Neal's TDC thread for how.

This technique sounds interesting. For us non-mensa types could you please explain your technique more fully (small words are greatly appreciated ). If you feel it would be more approprate on the SH3 forums, please post it there.

I like knowing different techniques as sometimes not every technique works for every situation.

Look at the link I posted just above.

I like that table a lot. In fact I have it printed out and by my computer.

However, it does not answer my question. The original poster stated that there was a technique that factored in the length of the ship. Using the table you refrerenced, the length of the ship does not enter into it. I am not aware of any speed estimation technique that uses the length of the ship, hence my interest in learning it.

As I stated before, I like to know multiple techniques when ever possible so in addition to using that great table, I would also like to learn the technique described by the orginal poster. It is my interpretation that they are different.

If they are the same technique then knowing the length of the ship is unnecessary.

It's actually a very simple formula, one that you can memorize(I did) after a few tries. Again, like the link said, the closer you are to 90 AOB, the better the estimation. However I got a lot of success in SHIII by starting the stopwatch(I used a mod for this and GWX has one included) when the ship started to pass my 345 degree bearing so that I could take the speed and then fire without having to get into a firing position a second time. In all my experience with SHIII, speed was the most important value for the TDC, you could be off in angle by 10 degrees but speed usually made or broke my success rate. Therefore, use Wazoo's guide to estimate heading and speed and get into a 90 AOB shooting position and then confirm the speed using this method. So here's the formula:

(3600)(length of ship)/observed time in seconds/1852m=target's speed

In other words, if it takes the ship one minute and 15 seconds to pass your vertical reticule, you would enter 75 into the observed time slot. The m besides the 1852 simply stands for meters and doesn't represent another value.

I agree ship length should be included in the recognition manual. They ARE given in that IJN ship wall chart that came with the game so a small printout could be made.

Could someone post that without infringing on the copyright? Maybe posting the info it contains(like stats) would be legal...

The information is also in the printed Rec Manual that comes with the collectors and deluxe editions.

The data is in meters but that is easily fixed.

Actually, the formula only works with meters but you could adjust the formula for yards.

Thanks for explaining that. You must be one of them smart guys

But I ain't . Could you explain why you use 3600 and 1852?

Sorry for the dumb questions, but dumb is what I do bestest.

This sounds like a really cool technique, and I would really like to understand it (if I am capable)

[don1reed]

3600 = seconds in an hour.

1852 = meters in nautical mile.


formula for imperial = LOA/seconds x 1.78

1.78 = 3600/2026
2026 = yds. in nm.

formula for metric = LOA/seconds x 1.95
1.95 = 3600/1852.
edit: If using meters use the 3:15 time
If using imperial use the 3:00 time

For planning purposes, mariners that use imperial, round off 2026 yds. to 2000 yds.
so...when you stretch out the measuring tool on the chart screen which .1, .2, .3, .4, .5 etc nm, think in terms of the 2000 yd. figure, i.e., .5nm = 1000 yds.
.1nm = 200 yds.
.2nm = 400 yds.
.3nm = 600 yds. yada yada each additional decimal place is increased by 200 yds.

10nm = 20,000 yds.

Thank you for explaining that!
I knew it was good hanging out with guys smarter than I am
