View Full Version : Check Boat Position

Does somebody know if there will be an option to check your Boats position with a sextant? I dont know the english phrase for this apparatus.
It will be great if the navigator (player) would be able to use the stars to determine their position...

Its a sextant in english too, did they still use these things in uboats? I would say pretty def no for one of those in the game, but who knows!

http://forums.ubi.com/images/smilies/cry.gif i hope they will involve this. Actually i dont know how to use this thing, but if its more realistic its more funny! i asked myself, cuz yesterday i saw "das boot" and Mister Kaleun said that he needs the Sextant to check the position... amazing

I dont think that this is in the game.

When your really lost you need to use it, but i doubt you will ever be that lost.

The basics are you get a reading of the height of the sun when it reaches its highest (midday) and then you can tell what latitude you are at (how far north or south) Its impossible to tell longtitude (east west) with a sextant. With the crew plotting direction and speed ect, they would always have a fairly good idea of where you are, especially if you sight land everyso often. Dont they get into a massive 2 week storm or something in das boot to get lost?

If you can say when the sun reachs the higher point, you can say latitude. So yes, you can say it with a sextant, a crono (were developed just to provide this info! A british admiral in XVII century sank his fleet because he did an error of some miles with bad weather: no one can rely on their mere observations) and a table of sun possitions.

I always imagined that they definitely used it - often. Simply keeping track of speed, direction and duration and relate it to a known starting position is not reliable over time. Small inaccuraries will snowball out of control, since these boats often stayed in mid-atlantic for months with no landmarks, and no way of accounting for drift. In Das Boot you see Kriechbaum using it twice - once using Venus as a measuring point (you can use stars too, as long as you have an almanak for it, right?). And he mentions his inability to use it as the cause for them to get lost during the storm. But I am no sailor http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif.

I would definately like to see it in-game, too. Hoping it, actually.

With the use of a sextant and a chronometer and some tables and math one can get both latitude and longitude.

Jose, I guess you mean longitude.

Listen to the "Viking"! They have long and succesfull history of sea navigation.
Mainly done by the sun, simple wooden rotary disk device and the gut feeling.
A lot of marine terminology in use today comes from them. (port, starbord...etc)

They definately did use sextants in and after WW2.
When there is no land in sight it is the only way to get your position.
Dead reckoning requires you to know a lot of factors and increases in error over time.
Radio, radar or satellite naviagtion began to grow after WW2.

make your own sextant.
