To all of you that can't use Optimal Angles from hmm's site, here is the answer to your prayers.

1. Download and install Adobe Air here

Adobe Air

Then download the application and install it.

Velocity Made on Course, Velocity Made good to Course or similar.

VMC is a generalisation of VMG. (But outside of sailonline VMC and VMG may sometimes be used interchangably).

VMG tells you how fast you are moving into the wind (ignoring any movement sideways compared to the wind direction). When sailing upwind you want to maximise VMG, when downwind, minimise (VMG is negative in that case).

VMC tells you how fast you are moving in some direction (ignoring any movement sideways compared to this direction). To calculate VMC you first need to choose the direction. I believe this direction is called "bearing" in Aaron's tool. This "bearing" can also be automatically calculated when you enter coordinates. If you enter the true wind direction (TWD) as bearing, your VMC will equal your VMG.

outlaw wrote some posts on solfans about using VMC for various things. The concept of VMC is very important for a full analysis of your position within the fleet and your route to the target.

What has happened to the AGage's Optimal Angles tool? I used to be able to call it up quite simply, and use both it and the Isochrones facility. Now it requires several steps each time and I get only a little screen that is specific to one race only. If I wish to use it in another race, I have to call it up with Google all over again, and the Isochrone tool is not available. I was recently 'converted' to Windows 10, and it has disrupted all my previous systems and names, so it may be the cause of all my problems.
If it breaks, it's not strong enough--if it doesn't, it's too heavy.

Rod - Before you type your boatname and password,
click on races and choose All Races at the bottom.
Then you you don't have to log in and out for each race.

I made a very minimal VMG calculator. Go to http://sol.kroppyer.nl/ and there's a link "optimal angles" on the left. It should open a pop up where you can log in with your sailonline username and password. It reads the polar from sailonline and the current wind direction and speed. You can also enter wind direction and speed manually. You can be logged in in multiple races simultaneously by having multiple windows open.

In the future I might add some more features, like VMC and/or a visual aid. But this will probably require a bit of UI design as well to make it look simple. As always: if something doesn't work, or you have ideas for improvement, just let me know.

That doesn't look anything like what I get when I call up AG's Optimum Angles Tool. What URL are you calling up?

Africa by Sea - Abidjan to Swakopmund


Our exploration of Africa by Sea continues. Next, it’s off to Swakopmund, on the water’s edge of the Kalahari desert.

More likely than not, we’ll have to beat into it in our Steinlager II, to finally find some shelter behind the walls of Platz am Meer where there is a marina of sorts. Only 2200nm!
