hi all

i dono if this topic was already treated, there are so many i couldnt hv a look at all of them.

i think there should be a coefficient for the races in order to establish a real and better representative syc members ranking.
indeed i guess it is not fair to spend 2-3 weeks in a race and 2-3 days in another and to have the same weighted points.
and more, the number of boats in a race is also important for the dnc or dns. so there should also be a weight for the number of boats entries, with a time limit for the registration. the higher the number of boats registered is, the higher the race weight should be.

i would suggest to use a rating system as follow:

race from 0-500 miles coefficient 1.0
501-100 miles coeff 1.5
1001-1500 miles coeff 2.0
1501-2000 miles coeff 2.5
etc...
the formula to use can be:
race points = race ranking x coeff x nb of boats registered / 1000

timed race: coefficient 1.0
the formula to use can be simple in order to make the timed races attractive:
race points = race ranking x coeff

or a system similiar to the above. any comment?

Hi all,
the proposed system looks nice. Give more motivation and reward to the long race. (forget my actual position, please!)
Was already proposed in the past?
May be we can open a survey on it?
Question to TUR Aklinyolu1: have you tried to elaborate ranking with it using the last 10 race?
Regards to all
Gilles

Although this is an interesting idea, I don't think a race is worth more just because it's longer.

Long races require different strategies and abilities. For example, weather forecasting is more important in a long race, while finer points of tacking, hitting marks, navigating among islands is usually a part of the short races.

I can't think of any other sport where the length of a race is weighted higher. Do we give multiple gold medals for longer races in track, swimming? Is an overtime victory worth more than one in "regulation time"?

I think as long as we have a good balance in length of races offered, the current system is better.

Thanks.
Bob, to answer your question, yes here in the real races with several legs, the longer races have higher weight. I am not saying it is a common practice in IRC races but yes it exists. Your other examples, I think they do not match with sailing as for example a swimmer or runner is participating either to the short or long distance, but a sailboat can participate to both.
Long races need more time, and this time value shall I guess be included in the calculations.
Meantime, the number of participant is also important as it directly affects the final result in case of DNS or DNC, and it shows the importance of the race. Few participant means better chance to win or lower points if DNS. Lots of participants mean lower chance to win and higher points if DNS.
Rgds.

To Bob:
"I can't think of any other sport where the length of a race is weighted higher. Do we give multiple gold medals for longer races in track, swimming? Is an overtime victory worth more than one in "regulation time"?
"

The Decathlon, pentathlon triathlon, are based on this system. And the overall victory usually go to the one tha excell in one discipline and is good enought in the others one, or sometime do not win any of the partial competitions but is always 2nd or 3rd. Is not a specialist but is good in all.
Regards.

After seeing last weekend's Orno Runt last minute race alerts and so, I would like to underline this subject again.
I really don't see why Sailors shall be punished with DNS or DNF under such conditions?
Why do the November Transat and Orno Runt races have the same weights?
Thank you

I like the fact that the races are rated equal. If a weighting system is going to be implemented we'll see less boats in "cheap" races (points wise) where you'll lose less by DNS than if you sail and end up in a bad position.

SOL should be all about the fun and sailing tactics, not about ranking tactics IMO.

Red Eye - Key Lime Pie-gatta 2025

Opposite the Bahamas at the tip of the Florida peninsula, we find the Florida Keys, a honky-tonk arpeggio of islands, where another SOL classic, the Key Lime Pie-gatta, so-called after the famous local condensed-milk-based tart speciality, awaits to be navigated once again. We’ll race its “Red Eye” 180nm in very-American Santa Cruz 52s, ignoring such artefacts as bridges, causeways and piers joining the keys one to the other and to the mainland!
