WSSRC Crowd weather routing

[SSolo]

We need some assistance from the SA brains trust
Adrian Banks (Banksy) and I onboard the OCD designed Open50 'Pegasus of Northumberland' (ex Kip Stone : Artforms, ex Phillpe Khan : Pegasus) will be attempting the WWSRC 2 handed Round Ireland Record and we need some, help in weather routing
- namely : when to set off and which way round to depart from the start at Dun Laoghaire

The WSSRC record for the 698miles is 3d 19h 41m 39s and we want to beat it!
We will also be setting the first IRC Round Ireland record and also the first T3 disability (and hopefully outright) sailing record

Banksy has Parkinsons (T3 disability) and has taken this as another challenge in live. He has smashed Parkinsons in the face and demanded that he defines what he can and cannot do!!
This year we have will be raising funds for Parkinsons Cure Research Foundation: Parkinsons is the fasted growing neurodegenerative condition in the world with over 145,000 in the UK having to live with the condition - 1 in 37 people will be diagnosed during their lifetime, help us to fight it.

so what do we need?

We are asking the SA sailing gurus to keep a weather eye on the weather and advise us when best to leave, which way round - remembering we both have 'day jobs' and best day for us is a Friday departure

The proposal is "SA Crowd Weather Routing" YOUR opportunity to part of setting 3 world records!

If you can help drop us a line via SA messaging

many thanks Ross

I am NOT a weather router, way above my competency; but I guess that anybody who could help you would ask first the polars of the boat. Do you have that handy?

 

[MR.CLEAN]

cool. good luck. Send to [email protected] too

 

[SSolo]

yes we have polars - will get them posted
we perform v similar to a leading Class 40 upwind and deep down, faster on the reach

 

[pqbon]

With provided polars you will probably get too much assistance...

The trick will be finding the highest quality assistance.

 

[SSolo]

yep - all info to put in tghe 'blender'

polars attached

Contact Met Office ?
In the past I used a Dutch weather guy who was a sailor. He helped numerous people like me. Now pensioned, so contact gone.

Can I suggest @Herman @damien and @Your Mom as extremely competent routers. I am sure there are others, but I'm not aware of them.

I'm not sure whether any of them would have the time to undertake this size of an undertaking. I wish the project luck, and hats off for doing this.

Thanks. I'm pretty good with using zezo.org for routing virtual races... and I've done plenty of real world sailing including some real world offshore stuff... but I've never actually used a router on a real world boat.

Hi, thanks for bringing this to my attention @Tunnel Rat.

What an excellent project to raise money for a good cause.

Currently I'm weather routing The Ocean Race IMOCAs on a daily basis which takes 2 hours/day up to the finish. I'm not sure what month you had in mind to start, but I will be rather busy for some time up till TOR finishes in July. Then on holiday in August.

Some questions and remarks beforehand:

1. Are there any special marks to be in or excluded in the course for this record?
2. The polars posted above are actually a mail exchange regarding polars for the boat. And not a polar file as such.
3. Are the polars for the boat 100% synchronous? If you analyse your log files using routing software like OpenCPN or Expedition you could notice that these are probably actually asynchronous. Making a clockwise or anti-clockwise routing not the same if sailing over port side has another polar than over starboard side. A couple of percentages boat speed difference do matter on longer sailing runs. Especially when trying to beat a record.
4. After building the most accurate polars as possible, establishing the start windows is important. You could run in OpenCPN using the NOAA data climate plugin various start time scenario's for all Fridays in the year. This would provide various start windows with the best start opportunities. In these start windows you would then by on standby to see if an actual start could be considered, based on the various weather models. This start scenario analysis can also be done in Expedition using historical GRIBs. This analysis would take a couple of days up to a week to be performed imho. Which I don't have atm.

thanks - SA wont upload an excel spreadsheet, can post a PDF
attempted answers
no marks ;start line is S pier of Dun Laoghire harbour, can go clockwise or anticlockwise
see above re polars - will try aPDF

yes they are probably 'asynchronous' as we have newer sails since Phillippe developed those, but we can exceed them by 4-6%, and more when power reaching
yes running start window on a daily basis - my good friend mate Brian Thompson (yep that BT!) is also weather watching with and have just comee off a call with hime over clockwise or anticlockwise is best... the N Channel was my 'proving ground' as a kid/teenager and getting out of the way early has advantages
ideally we want a nice Low 'slow' moving across central ireland, but we accept we will have to take a compronmise

Sounds like a cool project. What boat currently has the record?

qtVlm is a navigation software designed for sailing boats. It is also a free weather grib viewer that accepts all kinds of gribs. It can read and display maps in various formats: Vector charts (S57 and S63), Raster charts (kaps, geotiff, etc), Visit My Harbour charts and mbtiles charts.

yes it will accept custom polars and utilises free gribs .

Round Ireland Sailing Record by Pamela Lee & Catherine Hunt Just Gets Better & Better

The Round Ireland Sailing Record is a bit like Ireland herself. It's complicated by Partition.

afloat.ie

As to our potential
In the 2016 Round Ireland race, the same race afloat.ie incorrectly credits Michael Kleinjens/Ian Wittevrongel setting a new 2 handed record of 3d 22h 43m 45s, Chris Briggs and I went round 2 handed in 3d 19h 53m 6s on Pegasus, 3rd on the water to Ramble and Teasing Machine

So we actually held the record onboard Pegasus until Pamela and Catherine beat us by 12 minutes... Chris and I had not raced the boat 2Handed before and had a number of major problems reckoning we lost at least 2 hours during that race. With better winds the polars indicate we have a sub 3 day potential

Figaro 3 currently holds it. The Round Ireland Race and the WSSRC are 2 different records and start from 2 different places.
