But look at the advantages!

Deep water fetches of 2NM are everywhere. All our coastal seabreezes come in over such a fetch. Botany Bay, Port Phillip Bay have sufficient fetch. ( Even Lake Illawarra if you head out west beyond the sandbar.)

Many sailors might also find that the optimum wind for pbs in open water is between 20 and 25 knots. You could be in the pb zone 2 to 3 times a week rather than once a year.

I couldn't agree more re. open water, wind speed and PB's.

And over here in the West at least, I reckon the ocean is cleaner and generally nicer.

It would be good to have some sort of "Open Water" focus to provide balance to sailing the mostly inland shallow flat spots.

Just a quick update from the GPSTC homepage

Logit app for phones is for feedback but not accepted for posting data to GPSTC.

Recommended units are GT 31(discontinued), GW 52 (data is verifiable), Canmore GP102 ( in testing appears reliable but lacking error checking data).

Please keep a copy of your files as they may be required for verification. No file on request and result will be deleted.

We have some concerns about the accuracy, and therefore fairness of the use of the GPS-Logit app for posting in the GPS-TC using current model Android Phones. The current policy of GPS-TC is that GT-31 should be used for posting Doppler based data (D) by individuals and team members vying for the top positions. The GW-52 is also approved for use in the same way using 5hz logging. GPS-TC also allows the legacy pre GT-31 GPS (mainly Garmin) that only produced speed results from positional data (T), but only for those sailors not contributing to team scores or in the upper section of a category.

The Canmore has been approved for use as it sits somewhere in between GT31/GW52 and older units. It has the potential accuracy of the GT-31 as it is a Doppler based device, but it has very limited verifiability.

If you are posting results that are counted in the team challenge in a competitive team you should inspect the results closely in a stand alone analysis program (GPS-Results/GPSAR-Pro/RealSpeed) for unusual results and errors. Preferably, team captains or the team 'tech guru' should help with this, and if there is any doubt the files should be sent to one of the GPS-TC technical advisors for a second or third opinion.

Ian, I can sail on 'PB locations' 60-100+ days a year now. I am pretty sure that applies to a lot of other people as well. I have not sailed a PB for over 2 years though, and they were in a canal! What I require for them now is ideal (and very rare) wind conditions. The same thing would apply to any venue, be it closed waters or 'open waters'.

There are multiple definitions for open waters. Do some searches. What I am saying is that none of us have the same idea of what that means to us, and it's no good trying to make up a new definition of 'open waters' just for some record, when accepted definitions already exist that differ from what we are thinking and would just add to the confusion.

Far better to come up with something that actually relates to reality.

The reality is, some people are keen to differentiate between artificial/man made speed courses and Natural speed venues. They are all thinking of very flat water in this case.

If you want to try to define some sort of record for totally unsheltered waters (open waters), good luck! I just don't think it is in any way practical.

That was point I was trying to make Sailquick, Open water sailors aren't dependant on "ideal (and very rare) wind conditions", they're more likely dependant on an improvement in skill to get a pb. 25 knots again today on the Illawarra open water. A 40 knot 2 sec is theoretically possible right now if you have the skill. Not too many sailors who might be going for an open water pb are going to say they "need more wind".

"There are multiple definitions for open waters. Do some searches.."

I googled "open water definition for speedsailing purposes" and got bounced back to this thread Which definitions were you thinking of?

Anyway my suggestion of " 2 NM of fetch over deep water" is just a suggestion. Other suggestions welcome. But a good percentage Australia's 19,000 km coastline should qualify with onshore winds.

( By "deep" maybe just deep enough that you can't touch the bottom with a big toe, that would be easy to determine for a not-playing-for-sheep-station competition ).


ps.
Another advantage to add to the list.

For board manufacturers... they could market specialised open water speed boards.


Of course there's lots of discussion and opinions here already on what board is the best for open water blasting, slalom, mistral, free ride, tabou, someone mentioned a Starboard Acid the other day. But until we start posting comparisons, who really knows?

I believe PBs should always be checked, at least by the Team Captain.
I know it's not sheep stations but it's nice to know where you stand in reality
The top few teams results should be scrutinised more than others for obvious reasons.

Good example why phones not acceptable for GPSTC

They give a good approximation (top image) but they can add 2.6 knots to your peak speed (bottom image) Blue track is phone.

Can the top team captains also check for steroid use too. And unfair use of carbon inserts.

Im not a top team captain so I'm in the clear.

My other team mate uses Turkey to relax out on the water.
