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?

Fremantle to Bali 2022
It is time for a revival of one of Australia's iconic races, the 1427 nm long "Fremantle to Bali" race, and it's considered to be a true test of seamanship.
Last raced in 2021 Super Maxi 100, we will do it this year in a Sun Fast 3300 which is considerably slower!

Baker Lake Ice Race 2022
Up north, it’s Winter, so time to put your skates on, but first you’ll have to airfreight them, your carbon spars, your mylar sails and your DN hull to Baker Lake, for a 109nm race, the first of 4 (3 to count) at high speed before the ice melts! Well inside the Arctic Circle, this is a cold, cold place, where the wind is rarely benign. No Performance Loss, so put your goggles on, wrap up well, and try to get round as quick as you can!

Christmas Is (Pac) to Christmas Is (Ind) 2022
Two waypoints, start and finish, and between them 5827 NM of two oceans. Not much time if we want to sit at the Christmas Eve table. You will need to maintain an average speed of over 10 knots, so prepare your Volvo70s well and choose the best of the many possible routes. Hands up everyone who knew there were TWO Christmas Islands?! OK, maybe you have sailed this Sailonline course before... but it's time to get ready for the 2022 challenge of racing between Christmas Island in the Pacific to Christmas Island in the Indian Ocean! Please have fun! Fair winds!

The Three Kings Race 2022
The Three Kings Offshore Race is a 520 nm challenge, in Farr 38s, from Auckland (Orakei) up and around the Three Kings Islands and then back to Auckland finishing where you started. Manawa Islands (Three Kings) are a group of 13 uninhabited islands about 25 nm northwest of Te Rerenga Wairua aka Cape Reinga. They're also about 250nm due north of Auckland, known also as the world's best diving and fishing locations (although hopefully, you won’t be fishing too much during the race, or diving for that matter) and it is just a beautiful yet rugged place that is a must see for anyone who loves the oceans.
