2012-05-03 15:07:34 - Compute Optimal VMC and more
I posted a new tool to compute optimal VMG/VMC with a few options, read more about it here
Is an Adobe AIR app, so runs on Linux/Mac

Enjoy!

I am in awe of your abilities! My boss, however, thinks I should spend more time working and less time playing with little boats!

Awesome work, AG, soon I will just sit there and stare on this tool ... :-)

Compliments for this stand alone cross plarform tool. Does the possibility exist to also send navigation instructions to the logged in boat ?

Agage' I don't understand the theory behind your new tool---Do you care to conduct a seminar on the care and feeding of such an exotic 'animal'?
If it breaks, it's not strong enough--if it doesn't, it's too heavy.

A very nice tool Aaron,
never again I've to import polar.csv into excel :)
Some minor bugs are onboard:
if the browser looses the connection (red time display) the angle tool seems to loose it too, and doesn't come back (sometimes).
Switching between SWR6 and Hiroshima doesn't work, the tool stays at the first race logged in.
I often use a percentage of VMC/VMG opt, like 95% of VMC opt to stbd. Would it be possible to add this feature?
ciao

K3:
Not sure I would call those bugs as such - if your Browser loses connectivity then is reasonable that other software, especially connected to the same server should also lose it. I didn't realise you could't load 2 instances of the program for 2 races - I will see what I can do about multiple race support.
I originally intended to have it as a Flash application in your Browser, where you can simply load 2 versions - but there is issue with getting the data from SOL when the app is online (works fine running off local machine though).

Re the % idea - I'm not sure I get what you mean. What does it mean to sail at 95% VMC - for each tack there will be 2 headings that both have a VMC = 0.95*OptimumVMC. How should it be automated? User inputs 'high or low' or something? And do you mean 'At a heading where my VMC is 95% of the max' or 'Within 5% of the heading'?

In a way, I would rather keep things simple - there are many such small extra things that can be included - and soon the UI is somewhat bloated or overly complicated for how it will be used 95% of the time.
For 'X% VMC' it might be possible and easier just to have mental 'rules' like 'Every degree off I sail is 2% lost VMC' or something?

But of course, I can look into a specific feature if it would benefit a reasonable % of the users.

I modified it to handle multiple races at once. The page on the blog has been updated accordingly.
If you already have it installed, the installer will prompt you to update to the new version.
Of course, the original version will continue to work.

Africa by Sea - Swakopmund to Maputo 2025


Time again to continue our exploration of Africa by Sea, which now takes us around the tip of the continent at Cape Agulhas and up the coast of South Africa to Mozambique’s marvellous Maputo, where we should find good anchorage in the bend of the Rio Espirito Santo (Umbuluzi) once we’ve cleared the 60m high Maputo - Katembe suspension bridge. It’s 1900nm and we’ll be glad to be sailing our comfortable and sturdy Xp-55, as we will certainly experience more headwinds!

TuziTekwini TIMED Race 2025

Sailonline is delighted to have been invited to partner with the King Shaka Yacht Club (KSYC) of South Africa to bring a virtual version of the Tuzi Tekwini Ocean Raceto our online community.
The Tuzi Tekwini Ocean Race is a near 90 nautical mile race down the east coast of South Africa from the port of Richards Bay to the port of Durban. Achievable in a single day and seen by some as an easy mile-builder, the course is more tactical than some think and should not be underestimated. This iconic race promises to be an unforgettable experience for yachting enthusiasts.
Our online version of the race will be a TIMEDrace so you may RE-REGISTER HEREto try again after finishing a run. You will have 13 days and 11 hours to test your skill and decision making after the race opens.
