2011-06-06 03:38:48 - data usage for sol
I'm considering a pre-paid plan with a mobile usb dongle so that I can have decent internet connection on the boat. Question is: How much data does sol take to load? How much to pick up boat updates, and weather changes?
There was some talk of this in the past someplace in the forum and in chat. I seem to remember that it could take as much as 10 Mbps to load, but don't remember amount to run for say 1 hour,
Is there a way to measure usage? Has anyone done so?

Hi Jack!

I took a look yesterday on the Vancouver race.

14 hours continuous used up 75 Mbytes.

This included opening up a 2nd sol tab(once) to check on another boat. Plus opening up about 20 tabs to look at links referred to on chat and the Imsyc race boats.

Hourly download is in the region of 4 - 5 Mbytes per hour.

Regards
George

client is about 800Kb

How much to pick up boat updates,
About 500bytes, which equates to 2Kb per minute.

and weather changes?
The wx, race and map data all depend on the size of the map/fleet - I just used the Vancouver race to have a look at exact numbers - the fleet file is 18.1Kb. Wx was about 1.6Kb. The tiles for initial map load were just over 300Kb.

There was some talk of this in the past someplace in the forum and in chat. I seem to remember that it could take as much as 10 Mbps to load, but don't remember amount to run for say 1 hour,

(easy way) You could use Google Chrome's 'Developer Tools' and peek at the network - it shows a running total.
To say it can take 10Mbps you are confusing speed with size. It may 'burst' at the full speed of your own internet bandwidth, be that 3.6 or 7.2 Mbps on a 3G wireless, or 150Mbps on adsl2, but will NEVER sustain that for more than a few seconds.

Jawz numbers are pretty typical I think. If you allowed 10Mb per hour (a high value) and factor how many hours per week you spend on SOL you will never fall short.

Maybe they are different in the US, but about the only mobile data plans here that would not provide enough quota are the small 'Email Only' ones around 2-500Mb per month. 2Gb should cover even the heaviest of SOL users, but consider price per Gb to - and that you will probably want to browse other sites (possibly with even more data).

Also bear in mind, having the Navigation page on brainaid's toolbox open will eat a little bit of data as it refreshes periodically, as will any tool that reads SOL data, like his NMEA proxy.

Most browsers do a good job of caching content. I can reload a race, and FF and Chrome both report using wx from the cache, obviously race files cannot be, nor anything generated as a response to client requests. So the 'penalty' for closing and reopening a race is quite small.

I have a 12Gb 3G mobile plan myself, and use alot (comparatively) of SOL data - staying logged into races for long periods and using brainaids NMEA - I also download movies/tv shows, play other online games and alot of other data besides, and never go over - mind you I could use more if it were available ;-)

I just used the Firebug plugin with Firefox, opened Vancouver and let it sit for 1 hour - it resulted in about 3.3Mb of data (about 750Kb of which was in cache) - no commands or chat outgoing - but that is only small data so this is around an 'average' for a SOL race (medium size map/wind/fleet?)

Thanks Aaron and George. That's some useful info. Now I think I can make a good choice without over paying.

Organized by the Ocean Racing Club of Victoria, the Westcoaster is renowned for its challenging conditions and adventurous spirit. This year, our SOLers will tackle the course in the swift and capable First 47.7, a yacht launched by Beneteau in 2000, built for speed and endurance in long ocean races. Get ready for an exhilarating ride in one of Australia’s most celebrated yacht races!

Refeno Rally 2024


Although since 1986 this 300nm course from Recife, Brazil, to Fernando Noronha Island has been run many times IRL, we have only used this route twice in SOL. This time it will be the route of the last race in the ARCH 2024 classification.
Although the winner of the general classification can already be determined, the fight for the next places on the podium should be fierce. There are several contenders and Dofour34 have them at their disposal. Since we are starting in Vida_Maldita's home waters, he will give us a 30-minute handicap. Or maybe we should give it to him? 😊

The Beagle in the Azores 2024


And west the Beagle went one final time to round the Cape of Good Hope on May 31 1836. Ashore, Darwin met up with the Astronomer Royal, Herschel, who just happened to be in South Africa at the same time mapping the southern skies. After sounding out his many ideas on evolution and extinction with Herschel, the Beagle now sailed north, stopping briefly in St Helena, Ascension and Brazil, and the Cape Verdes again, to reach the Azores on September 19, 1836. Fitzroy and Darwin at this stage were in a hurry to get back to Britain, but online in 2024 we will stay a little longer to explore this final remote archipelago in our virtual Tall Ship Class B Beagle, 630nm round and about the islands, minding as always in these waters not to bump into any large cetaceans!

Christmas(W) to Christmas(E) Island 2024

Two waypoints, start and finish, and between them 5827 NM of two oceans. Not much time if we want to sit at the Christmas Eve table. You will need to maintain an average speed of over 10 knots, so prepare your 90ft well and choose the best of the many possible routes. Hands up everyone who knew there were TWO Christmas Islands?! OK, maybe you have sailed this Sailonline course before... but it's time to get ready for the 2024 challenge of a reversed race, starting in the Indian Ocean, racing to the Christmas Island in the Pacific! It also marks the conclusion of our prestigious Ocean Race Championship 2024. Please have fun! Fair winds!
