How do I measure speed?

Notewire · 09-28-06, 05:49 AM

This is a good thread, and gets to the meat of helping us improve as Kaluens.

Payoff, does that work regardless of range? It has been a long time since I studied geometry, but it seems that range would affect knots given the time from bow to stern.

I will say, that I am working on this one myself - as I had been using the 3:15 rule exclusively - but then I started playing with no map contacts - Yikes! Now the 3:15 rule is much harder - as it is difficult to guage the range perfectly. Also, with NYGM - the watch officer doesn't give you uber range estimations. Now I am working on a 6:30 rule, and dividing by two to get speed, but still the Fast 90 shots are very difficult.

Anybody got any good tips?

I've been trying to ignore the watch officer's range reports (GW so they show). The stadimeter is tough to get a good range a lot of the time. I've been getting better results I think by putting the vertical hashmark line in the scope/UZO on the target and then getting a read on the target's size in terms of # of hashmarks, i.e. 1 1/2, 2+ a bit etc. Sounds inacurrate, but I think you can eyeball it easier and more accurately this way, rather than trying to hover with the stadimeter. When I get my # of hashmarks, then I click the stadimeter tool on the hashmark measurement to get the range.

You could try my Time-Distance-Speed chart that loads into the Nav map screen, very simple to use but requires a 1.5minute timer (stop watch etc).

Just download my "Mini Mods", readme doc supplied.
Cheers.
Edit: PS. rename the downloaded file from hyperupload to "Minimods.rar".

Yes, this is very accurate, because the boats length is constant. I found this method here at Subsim, I forget the original author. The key is to be as close to 90 degrees AOB as possible. Of course if you are way out in front, with the target coming toward you, it is hard to get a good read. I generally do this three times with great accuracy at all ranges. Just set the crosshairs out in front of the target and man the stop watch. As soon as the bow touches the crosshairs start the watch and follow it through to the stern.
I like this method because it can be done in short peeks, allowing for minimum scope exsposure.

For those who seem to have problems with the 3:15 method on higher realism settings (or even overall), try this link:

If you think it's usefull, post on it so other people can have easier acces to it.

Need anoter example? look at the "Video Hunt" thread here:

originaly I was thinking about doing more and better video hunt threads, but comunity interest in such threads seemed to die very quickly.

Ok, about finding speed by counting the beats on the propellor sounds....is there a way to get this to work in those mods which disable it(i.e. GW 1.1a, etc)?? I think this is a cool feature and would be nice to be able to do...and have asked about it before, but could not get a definitive answer...I tried replacing some files in the sound folder, but I am not sure which ones to replace and what to replace them with. Should I use sounds from stock or from NYGM, i.e. was this feature available in stock 1.4b? I could do some trial and error, but in the event that I can be spared of that does anyone know?? thanks.

stock game with patch 1.4b does support measuring speed with sound.

...as to the mods... well, only the modders themselves can answer that
