2017-05-20 21:14:04 - Constant night in Red Dot Leg 2
Can someone give me an explanation, why the sol map is showing constant nighttime in the Red Dot leg 2, when in fact, at this time of the year, the sun never sets?

Joanne/RainbowChaser provided me with this explanation:
"Dear Finn

At the time Sailonline was first designed, there was no possibility for us to race higher than, I think 66 N or S ... so wherever you see the day/night curve (terminator) in Sailonline at present is the limit of where we used to be able to sail.

The arrival of extended gribs, permitting us to get weather N and S of our original limit I believe occurred roughly at the same time as Aaron's death and, as you know, until very recently our Tech Team were not in a position to make any but absolutely crucial changes to our UI.

This requirement for the terminator to extend to both poles is some coding that I suspect is, in the world of coding, something not too horribly complex BUT is something that would take time to do.

I am copying this reply to our Tech Team so that they can decide if it is something they need to invest time on right now, or if it is something that is such a rare problem (how often do we race S of the Antarctic circle and N of the Polar circle?) that it can be put on a wish list."

Definitely not high on the (my) list! Even if it is a bit confusing, maybe mostly to those of us living quite close to a polar circle. There must be better things to spend time on, at least for now.
The tech guys are doing a really great job! Thanks!

Less bothersome than switching from night to day and back again, every 20-30 seconds in RD 3 race, LOL

The Vineyard Race 2026


For the 16th consecutive year, our SOLers are invited to tackle this iconic 250nm overnighter. The classic route charges out through the sound, leaves Buzzards Bay Light to starboard, rounds Block Island to starboard, and heads home.

This year's weapon of choice is the Beneteau First 47.7. A proven performer since its 2012 SOL debut, this Farr-designed cruiser/racer excels at leading real and virtual handicap fleets. Success will demand sharp tactical navigation, so watch the polars closely to conquer the sound's shifting winds!

New Ice Age 2026 - Scott Base to Neumayer Station


To complete our DN circumnavigation of Antarctica and our 4-race ice-boat marathon series, we continue clockwise, now departing from Scott Base back to Neumayer Station. It’s about 3500nm back as well, which, as said if there’s wind at all, should, well-wrapped in your DN-cockpits, not take you much more than five days. And remember: charts down here are unreliable – what is land and what is ice?!
