2017-01-09 11:42:46 - Optimal Angles Solution
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.

Application

Then when it is open, pin it to your process-line/create a shortcut.

The broken link for the application has been fixed on 11-08-2018!!

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.
See attached screenshot.

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?

Current Races:

Christmas to Christmas Island 2025

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, maybe quite possible with this Maxi Trimaran, but prepare your vessel 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 2025 challenge of racing between Christmas Island in the Pacific to Christmas Island in the Indian Ocean! It also marks the conclusion of our prestigious Ocean Race Championship 2025. Please have fun! Fair winds!

Andaman Islands PYOC 2025


The Andaman Islands are an archipelago, made up of 200 islands, in the northeastern Indian Ocean. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. These waters will be the theater of our next 240nm race in the ARCH 2025 series. Which one you choose depends only on you, i.e. your Elan 410 sport will leave the Andaman Islands on the starboard or port side.

Isla San Lorenzo RTI 2025


SOL’s SRC (Sailonline Race Committee) has taken us to some unusual places in the past, and San Lorenzo Island off Lima’s Callao peninsula is definitely another one. Housing a naval base and a penal institution, no vessel is allowed within 300m of its shores. Also, with no sources of potable water, it is a matter of debate whether it is an island at all, and not just a large rock. So, whatever you do, don’t be tempted to BBQ; you’ll be arrested and go thirsty! We return for the first time since 2018 to race thirteen potentially unlucky miles in J-30s; have fun!!

Sinbad by Balloon 2025 - Carnarvon to Dondra


From here, our home in Bharatavarṣa is now north west of us – said Sinbad to his fellow balloonists. Perhaps we can ride the wind first further north, and then catch the winds that every year bring the rain, perhaps not. It’s 2600nm and we could be aloft awhile, so, Master el-Quarters, victuals only, no sandbags, provisioning the giant hamper. It will be not a picnic!
