	My soft is ready (beta version) BTW I have found strange COG values : <cog>0.798365726218</cog> I think this is a radian value. Is'nt ? All the boats are going south this night on NSSANZ; I get : <cog>3.17281659391</cog> After conversion COG radian: 3.17281659391 COG degree: 171.88733853925 The right direction. I have not yet implemented TWA / TWS nor the sail selection. I have seen where DC Checker gets polars and gribs . Some more tests and I'll publish the beta version on my server. Jean.

	The english (and french) beta versions are here: http://voilevirtuelle.free.fr/SailOnLine/ge/ BUT... the Free.fr server does'nt allow to retrive data from an another server so you can't use directly these scripts. You have to download them and set up your own local webserver. If Solfan web site (or Kroppyer's one) could hosts this code (after extensive testing and maybe few improvements, any SOLers could directly generate and download his own KML / KMZ map of the Sol fleet.

	looking good! I would recommend using the sol account to retrieve data, then signing in can be done automatically. "http"."://www.sailonline.org/webclient/ authenticate.xml?username=".$nick."; password=".$pass.";race_id=".$race use $nick="sol" and $pass="sol". And this will list names and IDs (and more) of active races: "http"."://www.sailonline.org/webclient/ races.xml?filter=active" --- Last Edited by kroppyer at 2017-03-01 01:29:13 ---

	OK. I have made the modification : --- Implemented ---- 1) Get the list of active races 2) The user select one 3) Login with "sol" account -> return a valid token 4) Get the boat list and position -> conversion to KML / KMZ map 5) Archive : List of all KMZ files sorted by race and date. 6) the TWA set up the type of sail : TWA <= 40° -> Jib 40° <= TWA < 110° -> Genois 110° < TWA <= 140° -> Gennaker 140° < TWA -> Spinnaker 7) TWA & TWS act on boat roll : more wind, more roll 8) And last but not least, added new collada files for trimaran --- Implemented ---- Future improvements 9) Select which boats to display Attached zip: The updated version of 2017/03/25. Correction of fews bugs and many improvements like new models, Grib, Polars and tour. --- Dernière modification par jf44 le 2017-03-15 01:53:53 --- --- Dernière modification par jf44 le 2017-03-28 22:59:25 --- --- Dernière modification par jf44 le 2017-03-29 00:28:30 --- Dans le tourbillon du Web Attachments sol2kml.zip (3.5 MB)

	Hi everybody (and Koppyer / Kipper of course) I need clarification about grib restitution for SOL. 1) Are the U and V components of Grib files from DCChecker's SOLGribXml folder in m/s or in knots ? I think they are in m/s. 2) The U and V values are the TWS components, with U the vertical component and V the horizontal one like in the Sol'd blog https://daysailer.wordpress.com/2011/02/20/how-to-calculate-tws-and-twd-from-grib-components/ That's right ?

Newport Bermuda Race 2022

The 635-mile biennial Newport Bermuda Race is one of the oldest regularly scheduled ocean races, and with the Fastnet Race and the Sydney to Hobart Race, it is one of the three great classic races of the yachting world. Founded in 1906, this the 52nd running of the Bermuda Race can also be participated in online.
Entries are invited for one of the four divisions:
Double-Handed Division:
Jeanneau Sun Fast 3300
St. David's Lighthouse Division:
First 44.7 Asymmetric
Gibbs Hill Lighthouse Division:
Reichel Pugh 64
Finisterre Division:
Delphia 47
Details for each yacht are available in the ‘Particulars’ links below and be sure to register your online choice on the Bermuda Race Online link – there are some fine prizes to be won.
As in real life, you can only sail one boat in one division, so choose your virtual yacht carefully, and because of the unusual (for SOL) 4-division nature of the event, please note results will not count towards ANY Sailonline Rankings.

Geraldton to Cape Town 2022
A race in the Southern Indian Ocean is always entertaining, especially in a Riptide 50. Traditionally the course would be West to East, to take advantage of the prevailing winds, but this time the SRC is challenging us to an E-W course, from Geraldton in Western Australia to Cape Town in South Africa. A brief 4800nm!
