João, I hear you. I don't agree completely on some details, but in general: yes, to make some unwanted software impossible, availability of data needs to be limited. This needs to be addressed at sol's side (the server), and may have large (negative) consequences, but eventually, it is the way to go.

For now however, the only legal way to follow a boat, is to have a human present at all times. Software may read the data from other boats (it is available), but it may not send commands by itself, a human needs to to this. It may still be possible to have software take over the human role here, but at least this is plain illegal from 2017 on.

Viva Huib and all.

Again, thank you for your comments on this subject.

It seems an (immediate) impossibility to SOL engine crypt boat’s data.
Off course, if this was already implemented we wouldn’t be here by now, at least discussing this subject.

Concerning this issue, the actual SOL policy, to which I profoundly disagree and already explained why, still is:

A - To allow during races boats live data public disclosure;
B - No interest in return to the former status of data public disclosure only in TS periods of 1 hr.

Anyhow, as SOL policy and also Markku’s one won’t change, I have the following suggestions:

1 - Access to the http://sol.hmm.iki.fi/sollog/races/ only by means of COMPULSORY LOGGING using the same SOL boat credentials per boat (user name/”boat name” and password);

2 - Live information (pls see Note under) of all SOL boats LOGGED to each running race live data;

3 - Live information of all SOL boats (pls see Note under) that WERE LOGGED to each running race live data;

4 - For each boat, and for clarity purposes let’s say, boat “A”, live information (pls see Note under) of all the boats that ARE ACCESING that particular boat “A” live data information.

Note: Name of the boat and time period of boats data collecting.

If someone is getting my live boat data info, I’m entitled and have the right to know who is.

Implement this actions and I assure you some interesting surprises on the upcoming races.

A Big Hug

It may be possible to break the rule (which is why it's a rule, if it's impossible to break the rule (like "you may not go faster than the boatspeed given in the polar"), there would be no need to write it down), but breaking the rule can be detected and has serious consequences. The rule can be enforced, but at this stage it requires manual investigation. Just like the boatsitting rules.

It may be possible to have multiple boatsitters, but it is still illegal, and when we find out you'll be disqualified for the race.

It may be possible to have self steering software, but it is still illegal, and when we find out you'll be disqualified for the race (at the least, it may be worse)


You have to understand, this new rule is not a direct response to the problems with having live and precise data, it is not meant to target this one specific problem, it is meant to target a wider range of (potential) problems, it bans all software that steer the boat without human intervention.

This is not sol's final solution to the problems with live and precise data, if it is even a solution to this problem. Different solution(s) will need to come to solve this specific problem, solutions like JB is describing.

Happy new year to y'all.
quick thoughts, again I really don't share Joao's concerns...

1. All I see in Joao's PDFs is boats sailing VMG on TWA which is perfectly normal. Plus some noise from hmm's weather being sourced differently.

2. If you want to show foul play, use "compare stats". Robot sailing should be really obvious on that one.

3. Again I don't see how data logging would be particularly useful. Simply because pretty much everything can be easily extrapolated.

4. And amazing tactical analytics would be effort. Time spent on the go-fast problem, worth it. Monumental time spent on letting the computer do tactics? I wouldn't, benefits would be dubious, and tactics is the gameplay for me anyhow.

5. One could ask whether the forecast wind should be absolute... I say it should, because that's the requirement for set-and-forget router use, and having actual wind different from forecast would make a (now illegal) steering robot necessary.

6. One could ask what's the difference between follow and cover... Cover is a legit tactic, and to follow is frowned upon, but where is the difference? There is a difference, but it's somewhat ill defined.
Viva Huib and outlaw,

Good morning.

New Year and old problems.

For Huib.

Is it possible to establish the logging procedure to hmm’s live data as mentioned in my previous com?

For outlaw.

Do you ever asked yourself why IRL is forbidden to have live access to the other boats data - even with different boats in the same fleet, not mention with One Design classes?

Talking about tactics. You missed (as you don’t n know) the boats relative positions context where/when the RTW live race data was picked, meaning the unique “TWA” conclusion is … somehow reductive.

Knowing that someone is “looking” to your boat, not to mention, monitoring her, is different than not knowing it. Easily you wonder why.
Anyhow, extrapolations on boat data are also different from getting live precise infos from those same boats.

To better feel this issues, please try to make some SOL Sprint races where top 10 arrivals are measured in a few seconds. Try it, and then we can talk again.

A Big Hug to both

Of course you can force users to log in with sol credential before the get access to hmm's sollog, but
- hmm might not have the time to implement it
- everyone can use sol (or any other anonymous boat)
- computer savy people don't need hmm's sollog to get the data

if you would log who gets the data from the sol server in the first place, you'll see that everyone who's racing gets your boat data. Most people just won't look at the numbers but at the graphical representation of them.

I think the better option would be for sol (the actual source of the data) to only supply data from other boats that is less precise:
- reduce update intervals,
- reduce precision of course,
- reduce precision of position.
Some may be easy to implement, some may be hard to implement, some may have side effects, not all may be needed to achieve the goal.
Viva Huib and all.

Good afternoon.

I see, and quite agree with you.
The former update time (1 hour) was correct and enough, not the actual “almost” live and public data we have.

So, some random induced “noise” on the HDG and BS data (I don’t think the boats positions needs to be “worked”) and increasing the actual period (1 minute) for the boats data update, could be an acceptable provisory solution - at least 15 minutes - if it is (?) doable.

Is the flash-client only receiving and the sol-server indiscriminating sending every 20 seconds all data?

Would it not be possible to build a communication-initiating query into the flash-swf-client on which sol-server starts sending the data only to that logged in client. Not logged in? no data are send about this 'boat'.
This is already the case.

Once an hour all data is broadcasted to all like it is done now.
That's not how it works now.

It would imply a site like hmm's "sol race data centre" would not function anymore.
Being logged in as sol counts.

Vasco da Gama Ocean Race 2022

Point Yacht Club welcomes Sailonline to the 2022 running of the classic Vasco da Gama Ocean Race. This race is the oldest established international sailing event in South Africa and traditionally starts in the bay of Maputo, the old Portuguese colonial capital of Mozambique and finishes in Durban. Last year, and now again this year, the race was/will be from Durban to East London - circa 250nm in native Cape 31 speed machines.

Seoul to Seoul TIMED 2022
In this TIMED race designed by NZL_Scotsman, you'll start at Incheon, sail around 34nm WNW through the Korean DMZ towards the island of Yongmae-do and leave it to port, before returning to Incheon. Luckily, there is no military presence to contend with in this SOL race, though there's still plenty of islands to watch out for and not BBQ on. And once back in Incheon, you can even RE-REGISTER HERE for another attempt. Fastest round trip wins!

San Francisco to New York 2022
Cornelius Vanderbilt, who made his money - that his descendants enjoyed to spend sailing and racing yachts - by recognizing that getting from the East Coast to the West Coast of the USA was best done by rail, would have been more than a little amused to see SOL organizing yacht races over the very route by water he made redundant. It's about 13,000 nautical miles, which compares with less than 3000 statute miles by train! Six years ago, the best SOLers managed to complete the passage from San Francisco to New York in around 36 days, sailing our much-used veteran ocean greyhound, the Super Maxi 100. Time to try again, this time on the VO70. If you aim for a SOG of 18kn, it'll only take you a month.
