    Thanks Jacob

    Now we know ho to calculate the VMC. But to find out the best one you need to do a lot of calculatens in different directons (or). As your boatspeed is different (as the polar shows)at differents angel. I.e if you do 5kn with 55 deg to mark or you do 6.5 kn at 60 deg you had to calc both to find hos is fastest VMC.

    Any easy way to do that?

    Do any have the formula for VMC? Or could you calk. it by change the TWA to the dir. to mark.

    Rolf

    EDIT: I found it. Its COS(angel of your boats directions) * Speed
    or COS(60) * 5 = 2.50 knots made north (vmg)
    if mark is N (360) and you sail 60 deg. in 5 kn.

    And BTW VMG is "Velocity made good"

    Re: Feature request, what would you like to add....

    I want a function were you could chose 1--5 opponents to track/follow. I.e It could be enough if the boats shape is stronger coloured so you easily could find them.

Thessaloniki to Port Said 2026

Welcome back to the Eastern Mediterranean for the fifth race of our Magical Mediterranean Series. Only marginally less unlikely to be ever raced in real life during SOL’s lifetime than our previous race from Tobruk to Iskenderun, this 710nm race takes us from Greece’s ancient northern port of Thessaloniki through the Aegean island maze, south east into the Levantine Sea to a finish in modern Port Said, in splendid Swan 65s!

TuziTekwini TIMED Race 2026

Sailonline is delighted to have been invited again 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 two weeks to test your skill and decision making after the race opens.
