Thanks Tuule.
I'm using windows and didn't know that :-)
My I ask what does VMC stands for?
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.
Thank you so much for the detailed and fast ifnormation.
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?

Golden Globe Race - Leg 1 to Storm Bay
Welcome, all, to the 2018 Golden Globe Race and Sailonline’s virtual version of this iconic 50th anniversary rerun of 1968’s first ever non-stop single-handed round-the-world race in yachts and with technology in keeping with that historic time.
To reflect the challenge being undertaken by the real racers, as announced previously, SOL invites all who feel so inclined to add their boat name to the post in FORUM declaring you will race by the proverbial "Seat Of The Pants" (SOTP) with no outside assistance from routing software or other external aids, BEFORE THE STARTING GUN IS FIRED.
To simulate the real race which features a 90 minute minimum stopover in Storm Bay, SOL’s online version has been divided into two legs. This first leg then is from Les Sables-d’Olonne to Storm Bay. When the leaders approach Storm Bay, Leg 2 from thence back to Les Sables via Cape Horn, will open. YOU MAY NOT START LEG 2 UNTIL AT LEAST 90 MINUTES AFTER FINISHING LEG 1. The penalty for starting Leg 2 before finishing Leg 1 is NO RANKING. The penalty for starting Leg 2 within 90 minutes of finishing Leg 1 is 5x the time you started too early.
DO NOT START TOO EARLY!
Fair winds and good luck!!
