    Re: Isochrones
    Board » Technical Discussion
    I'm quite new to SOL and I don't use the isochrone tool much so take this with a big heap of salt.

    I also haven't seen any documentation on the isochrone tool. My impression is it shows where you'd be in X hours if you immediately make an order to COG Y or TWA Y and issue no further orders. Each curve shows one value of X (you can adjust the spacing between Xs with the "step" menu) and many values of Y. It probably tries hundreds of different values of Y to show a smooth curve. It seems to ignore the fact that you can't travel over land. It's similar to the polar chart but uses forecasted weather not the weather right now.

    It can give you an approximate sense of how fast you can travel in different directions. In open water (land no factor) your predicted travel times using the DC-enabled course predictor should be at least as fast as the isochrones predict if you choose course changes well. Over short distances (~1 hour) you'll only beat it significantly in directions where the polar curves inward and you need to tack, gybe, or hop. At longer distances its accuracy will vary but it's more accurate than I expected. Looks like I can beat it by 0-20% usually.

Carib Rum Run 2026


Ahoy, ye landlubbers and seasoned salts! Welcome back to Sailonline’s legendary Carib Rum Run, perfectly timed to kick off on International Talk Like a Pirate Day, 19 September!

This year, we command the magnificent Falkun—the ultimate high-tech superyacht modeled after the iconic Maltese Falcon. This 1759nm slalom takes us through the Caribbean’s rum islands to plunder barrels from local distilleries and deliver them to the rum-parched sands of Cancun.

Join SYC before the finish to disguise yer boat with a pirate name for this race only. Hoist the sails, sharpen yer cutlasses, and plot your winning course!
