After reading up on naval navigation, I found something pretty cool called a Maneuvering Board that navigators use to plot ship positions.

At the bottom is a very cool nomograph for finding out speed or distance or time just by drawing a line through two of the known values and seeing where the line intersects the third value.

For those who don't know (and frankly, I had never even heard of the term nomograph until 3 days ago), a nomograph is a representation of a mathematical formula that you can use to solve for different variables by just drawing a line.

Its like an instant visual calculator!

So, I decided to try my hand at making my first mod... and here it is:

So let's say you want to find the speed of a target after observing for 90 seconds. You measure the distance and it is just under .2km.

Just use your Ruler Tool to draw a line starting at 90 seconds, through just under .2km and then read off the knots (about 4 knots as shown below):

I have also been using it to help on convoy interception. In this example, I wanted to see how far a ship going 4 knots would travel in 140 minutes. Drawing a line from 4 knots to 140 minutes shows an intersection on the Distance scale of just over 17km:

You can also find how long it will take a ship going a certain speed to travel a certain distance.... all by just drawing a line!

I dunno.... I just find it kinda cool... http://forums.ubi.com/images/smilies/88.gif
