simple online way to measure sea distances

[chrisbitz]

I was wondering roughly how far it is from Medway to Ramsgate, and I was wondering what the easiest way was to measure the distance...?

is there a map where you can just click, click, click your waypoints and it adds the distance or something like that?

Thanks!

oh! found a really cool thing - right click in google maps, and chose measure distance, and then click click click your waypoints!

Haven't found how to change it to nm yet though...

I use the free download of Google earth with the NM straight line or multiple turning point distances from a to b.

That's exactly what I use "maps ruler 2" for (google play), just to give me an idea without consulting charts etc.

Navionics web app?

Click on the little divider symbol, it gives you a couple of pins to drag about and gives you the distance between them

Decimals of minutes of longitude on the side of a paper chart. Simples!

You can do it on Google Earth too.
Top of home page, on menu bar
Left click ruler icon
Window opens
Select measurement units
Select line or path (line only measures between 2 points)
If path,then
Left click on first point, move to next point click again and so on to the destination waypoint, the route is shown as you progress.
Total distance shown in the window.
I use it for navigation all the time. lol

ps a warning - Google Earth omits a lot of offshore rocks, reefs, sandbanks and other obstructions to navigation. However it is a very quick way to get an accurate route distance.

I was going to suggest measuring it in km, then converting it as I thought I remembered that it was a very simple conversion, i.e. 2:1. Before posting I looked it up in a reference book I use frequently and was surprised to see that a UK nautical mile = 1853.2 metres whereas an international nautical mile = 1852 metres. New one for me.

I had to use a screen shot of Google Earth of an isolated rock off Patmos to convince Navionics there was a rock there at all - ( I hoit it!) I do not like Navionics as the only way to see these isolated obstructions (if they are on Navionics at all) is the going into full zoom. I had countless ones like this on this years tour of the Aegean. They often only mark them as obstruction - you then have to right click and look at object information - which sometimes - just sometimes - has the depth of the obstruction - sometimes of only 1 meter - so why not use the conventional symbol for a rock?

Nories Tables, anyone?

Google Earth. The paddle wheel on my log is usually fouled so, to complete the logbook, I use the measurement on GE
