2013-10-24 18:14:18 - SOL with nautical chart overlay
Would really be cool to have overlay the real nautical chart while racing.
The topic was discussed some , ehm , many month ago, but failed because no free chart available.
Today spot on sailing anarchy, (thanks) that the NOAA is releasing his chart for free.

I agree that the 5161 for Newyork Bermuda is not the most interesting but the one around New York for Vineyard may be is worth a try to be the first platform of virtual sailing using real chart.

Someone that is able to implemet it for a test?

Yes, I agree that would be cool. However, as I see it these are the requirements we have for the maps to be used in SOL:

- They are available (i.e. free)
- The sailable area can be easily determined automatically (i.e. server can detect when boat hits shore)
- Different scale for overview and detailed view

The latest is not really a must but probably lacking a not-so-detailed versions of the maps would make sailing on other than the most detailed view impractical.

However, what most suggested maps are lacking is some kind of digital information on the shoreline which the server can read, just the map itself (as a picture) is unfortunately not enough. This is also what prevents us using google maps for sailing.

I believe the map data that some gps plotters use could be used by SOL, however I fear that they will not fulfill the first requirement from my list.

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?!

Cross the Convergence 2026 - Tenerife to Fernando de Noronha


The sixth race of our series of ocean voyages across the World’s convergence zones takes us back up the Atlantic to Tenerife, from whence we will depart on a classic transatlantic passage to Brazil’s Fernando de Noronha. It’s 2150nm as the albatross flies, but you will undoubtedly have to take some and sometimes sudden detours to get your Volvo 70v4 through the doldrums stretching across your path from the Amazon to the Niger.
