A thought on the handicap results: The top places are usually taken by SOLers who have completed very few races. One way to avoid this would be to use their best result as their rating until they have completed 15 races. Another way would be to increase their rating by a particular % based on number of races completed.

The rating becomes easier to handle after the initial 15 races are complete. This is function of how we are establishing the initial rating. Using fewer races would speed up this process, but risks having less valid initial rating.

Well... getting an initial Ranking is always difficult because of the fact that it's initial. ;)
I think no one would take an initial Value that serious to complain about it. Maybe one can mark it as initial or not confident in the Ranking.

I don't know the formula for getting an initial Ranking. If i would be asked how to get one that's converging relatively fast to a "real" value, i would suggest to take the arithmetical Medium of his ratings so far, until he's sailed a certain amount of races, say fifteen.

If that's too difficult to do, i would reduce the minimum number of Races to be sailed for an initial ranking, but introducing a Mechanism to lower this ranking afterward, if necessary.

I didnt actually notice the last few posts until after I had done this, but I tapped directly into the DB to output lot more data you could use (going back to Jan 1 2010)

2 files included:
* boats_data.csv - full race-id;race-name;boat-name;ranking;elapsed time;ET components (D;H;M;S) - approx 3.8Mb
This file is sorted by race start-time, and then each boat is in rank order within that race.
* races_data.csv - is data for all the races referenced in boats_data.csv - race-id, name & extra info like #started, #finished, race start time, polar used, Series etc...

56,845 data rows in the boats_data file - that will fill up ya spreadsheet!!

Note: the data is SEMI-COLON separated, as in the race data file 2 fields are themselves comma separated lists - so make sure to remember this when importing into Excel or whatever...

Also Note: The DB seems to have a few 'inconsistencies' in it, 2 or 3 races didn't record finish time (atleast, not in the way I grabbed it for other races?) and the like, SO - these are not included for consistency/completeness

Download zipped data here (914Kb)

HTH :-)

Also, if you provide me with specific formulae you are using, I could script it up and run it over the DB similarly to what I did here - then ideally integrate it into the ranking system

[Edit/Addendum:]
Please note - it is only because I have a 'non-racing' account on SOL with admin privileges that I could do this...
(And know just enough to write Python scripts to pull info out of the DB)

A preliminary attempt to make these results public can be seen here

It will grow and evolve in display sophistication over time...

Bookmark it - perhaps later it will be added to the Links page or something (looking into better alternatives)

Great Bear Ice Race 2025


You can fly to Great Bear Lake Airport, but if the ice is good, instead hire a pick-up truck, load your disassembled DN into the cargo bed and drive, first following the McKenzie River north, and then straight across the lake to the start of our final Ice Boat series race of roughly 100nm in length. The Airport authorities have agreed to leave all lights on, so you should just about be able to see where you are going as you zing and rumble, PL-free over the ice!

Chile Islands RTI Sprint 2025


Across the Canal Puyuhuapi from Puerto Cines on the Chilean mainland lies the Parque Nacional Isla Magdelena, and further west across the Canal Moraleda from Magdelena lie the islands of the Chonos Archipelago. Returning for the first time since 2017 we find ourselves in vari-charted waters here, with the mapping between physical islands and their names not 1:1 but rather some:some. It’s only 26nm but you could get lost! Good luck.

Christmas to Christmas Island 2025

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, maybe quite possible with this Maxi Trimaran, but prepare your vessel 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 2025 challenge of racing between Christmas Island in the Pacific to Christmas Island in the Indian Ocean! It also marks the conclusion of our prestigious Ocean Race Championship 2025. Please have fun! Fair winds!

Sinbad by Balloon 2025 - Carnarvon to Dondra


From here, our home in Bharatavarṣa is now north west of us – said Sinbad to his fellow balloonists. Perhaps we can ride the wind first further north, and then catch the winds that every year bring the rain, perhaps not. It’s 2600nm and we could be aloft awhile, so, Master el-Quarters, victuals only, no sandbags, provisioning the giant hamper. It will be not a picnic!
