Nice work Trombones,

We are having a good look at this and see if we can use this in more races at Sol. I am still in doubt about the rating system to use.

IRC info is most common in europe but the PHRF system looks interesting as well. Any ideas on this what you think is a good overall system and good for the Sol boats we currently have?

Sources of rating information is also welcome
I am a ex-admin of SOL who joins in from time to time.

The yardstick systems end up working pretty well in SOL given the number of boats racing. This race was skewed a bit as the class40 attracted so many more boats, but adopting 3way tie for first should auto-level the fleet somewhat as you could potentially score more points by racing in an under-represented class. Even with Colin's couple of hours off pace, the results are certainly palatable, and easy for everyone to understand, and we could very easily show CT ranking on the fly.

I suspect that given the strength of competition on SOL and number of boats this even simpler system would give consistently better results than single-number TOT/TOD.

On the other hand: Because we sail to exact polars, the vpp-based systems all fit really quite nicely. We can generate IMS/ORC-style certificates for any of our boats, and the rules for automating the calculations server-side are straightforward even for the most advanced scoring systems.

http://www.orc.org/rules/PCS%20Explanation.pdf

This gives CT results approaching the routed method, but is less transparent than the simpler systems. The server would keep track of the average accumulated TWS/TWD and update the handicap accordingly. Requires a bit more coding. These results could also be shown real-time, and should be reasonably fair. The only real knock is that it's trickier to visualise. Real-time ranking updates mostly takes care of that.

In any case, adding SOL certificate data to the fleet archive (with pd pictures and a little blurb) would be a great addition to SOL even without mixed fleet racing. The "Fleet" menu could go right up there in the blue menu next to "Rankings". ;-)

I must say, this multi-boat race added a whole new dimension and felt (to me) much like IRL YC racing. 76... the spreadsheet is brilliant!

So here is a fantasy question... would it be possible (server side) for us to pick a boat(polar) and then sail that in every race? This would be very much like club racing where everyone has their own (different) boat. I'll take a Swan or Hinckley, thank you very much! This would be a MAJOR change in SOL methodology but maybe something to consider for the future (?)

Nice work again to all!

Current Races:

Andaman Islands PYOC 2025


The Andaman Islands are an archipelago, made up of 200 islands, in the northeastern Indian Ocean. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. These waters will be the theater of our next 240nm race in the ARCH 2025 series. Which one you choose depends only on you, i.e. your Elan 410 sport will leave the Andaman Islands on the starboard or port side.

Isla San Lorenzo RTI 2025


SOL’s SRC (Sailonline Race Committee) has taken us to some unusual places in the past, and San Lorenzo Island off Lima’s Callao peninsula is definitely another one. Housing a naval base and a penal institution, no vessel is allowed within 300m of its shores. Also, with no sources of potable water, it is a matter of debate whether it is an island at all, and not just a large rock. So, whatever you do, don’t be tempted to BBQ; you’ll be arrested and go thirsty! We return for the first time since 2018 to race thirteen potentially unlucky miles in J-30s; have fun!!

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!
