I play with external view only. I like to see my handy work. The rest is checked or 95% play. It gets less difficult the longer you play. Sometimes a task force/convoy drops into your lap. Other times the task force/convoy blow on by and all you can do is watch them disappear into the sunset. It is a game of laying in wait. Chase when you have the advantage and ability to do so.

You can get a pretty good idea of the target's course from the first three bearings taken using the "four bearings" method. Probably 80% of the time that works ok for me, although it requires you to sit motionless and track the target for quite a while, which may cause you to miss out on a firing opportunity.

If you also make an educated guess at target range, the you can get a good first approximation of speed.

All measurements can then be refined after you begin actively tracking the target.

The fourth bearing, which should provide range and speed has never worked for me.

If you have vector math and trigonometry skills, you could probably solve it mathematically. I have created spreadsheets on my ipad that substitute for my missing crew.

I can live without the external camera. But when you turn the map contacts off, the game gets REALLY tough, and requires a lot of patience. I can do it, but do not want to spend all my life at sea.

Been there, done that. The problem is that, according to the unopinionated Rockin Robbins, the Americns did not know the correct lengths of Japanese ships. Thus, if one inputs the lengths, it is not realisitc.

Calculating speed in the manner you have described has been discussed many times previously. This forum has been around for quite some time.

Rocking Robbins plays with map contact updates on.

I deal with a target at 1000 yards, what i have more problem is with tracing an trracking a target at 10 miles with no map contact update.

Difficulty comes more from mods and your tweaks than game settings. However, if you plan to play with contacts off you need to learn to use the radar mod.

I go in spells, but when I get serious, I load my hard mod setup and cut contacts and the cam off. It takes time, attacking and evading a group can take several hours.

Default Radar Mod

This the mod created by Nisgeis called the 3D TDC and Radar Range Mod? That is a great mod, but it takes time to play the game using it. I was watching Run Silent Run Deep, and in one scene it appears in the background. I haven't thought about whether you could use Capnscruvy's mod (I forogt the the name) with map contacts off. That may be a possibility, too.

(Nisgeis also created the Torpedo Angle mod for setting the degrees when firing torpedoes so they create a spread. That is another sophisicated mod. And, if you want to leave the earth, activate MOBO -- somebody let aaronblood loose, and he went wild.)

The problems with four beaing is that they are difficult for convoys or task forces since the brings can be mistaken from the whole lengh of the sonvoy itsefl. Besides it can take some very long times to get a wie sprea of angles and the target is changing course pretty often in RSRD campaign. Thanks for the avise.
