A-Class Worlds 2017 @Sopot, 120 Entries & Bundock confirmed

Photo Harrison Rietman  -  Good numbers of entries for a new venue for the A-Cat Worlds. Sopot in Poland is the sailing spot for the Exploder local team. Top A-Cat sailor  Jacek Noetzel is organizing the event at the UKS Navigo Sailing Club. Worlds website is

Darren Bundock has confirmed his presence on the entry list, Bundy is pretty busy with the Youth & Olympic coaching for the Australian teams and maybe the only event he will be racing will be this one. With less years than other top sailors in the Class, Bundy has achieved top notch form in little time , he finisihed second behind Mischa Heemskerk in 2016 Worlds at Medemblik.

Shorter masts, new foils and new platforms setups like the 2017 Scheurer G7, are the ongoing developments towards the Worlds. This weekend the European Spring at Garda will see another match between Mischa & Tymek like last year and will be first test for new devels. Dna F1 has maintained platform as is, mainfoils too, rudders feature some mods, will get pics later.  D3 has been developing new foils since Medemblik , castings are now carbon cassettes type along extra long rudders (seen at Garda this week) .

Meanwhile teams continue to train at Circolo Vela Arco in Garda , Tymek & Jakub Surowiec arrived yesterday with their D3s, the F1s gang have been saling for some days with Mischa, PJ, Dodé and Arg Mehl among others.  Entry list for European Spring 2017 here. More info later on the week.

-- Sopot charter wanted: If someone has a D3 or F1 to charter let me know , is for friends wanting to participate.

America's Cup 2017 @Bermuda : LV Day 4 Teams review

ACEA vide daily wrapups clips are useless to see 2 seconds of  continuous action, glad to have the Teams themselves producing some media and footage each day. Above Day 4 review vid by Emirates Team New Zealand & Artemis Racing -   Day 4 Results report in previous post.

Artemis 'blamed' the no wins due to foil bad selection , addtional comments from Nathan: “We did a really good job at the start and won that clearly. On the next leg they got pretty aggressive, trying to give us a couple of luffs but they had some problems with their controls and crashed down so we took the opportunity to get round their bow. Then we spent the rest of the race trying to fend them off but at the top mark we just ran out of steam and they went past us”

Land Rover BAR Below comments by Ainslie, full D4 report by BAR  here
Thoughts on the racingBen Ainslie, Skipper and Team Principal: “It was a big day for our team. We’ve had a couple of really tough days with a couple of losses on the run and we really needed to turn that around. We had some pretty frank conversations last night, and we all knew what we had to do today. It’s a big boost for the team and we must now keep improving and moving forward."

America's Cup 2017 @ Bermuda: Great reward for the French Team

Good video by ACEA  with Triphaine Renard for Groupa Team France Logisticis going emotional. We are quite happy with the French Team grabbing the victory yesterday, lots of work with a reduced budget and lots of passion  involved , specially being THE Multihull Nation.  I can even dare to say, this is enough to reward their efforts. But I really hope to see more of Cammas and our F18 guys in these Series.

America's Cup 2017: Team New Zealand, Glenn Ashby: "We are Ready"

Photo: ACEA / Ricardo Pinto - Video: sent by Emirates Team New Zealand. Glenn Ashby is Ready , the guy extrudes confidence as few others and no matter in which situation: Racing solo in the A-Cats, even under speed handicap, or sailing along top notch helm Peter Burling and the entire Commando Task force of  Emirates Team New Zealand.
Special Cup for the Kiwis on their lone trainings back in Auckland plus all the innovative developments they always bring to the Cup.
We like Artemis and we cheer for New Zealand too, both with great chances to challenge Oracle in the AC Finals.

On the A-Cat / C-Class no jib style by TNZ, above practice racing vs Artemis, remember Oracle Tri vs Alinghi back in 2010. In the breeze the Wing alone (brought to the America´s Cup by New Zealander Design & Engineer guru Mike Drummond) might be more than enough.

On Mike Drummond check his Excel Obscura blog, where you can download a custom tracking app implemented in Excel by him: - We'll try with Mike to stream his tracking screen for those not able to watch stream or even follow tracking app. More on this later.

The tracking, with plenty of data is public and based on Live data provided by ACEA.

RB Video: Konstantinos Trigonis & A-Cats

Konstantinos sets sail for a new adventure on his eXploder AD3!
Posted by Iordanis Paschalidis - Konstantinos Trigonis Sailing Team on miércoles, 24 de mayo de 2017

Well produced clip by Red Bull on Tornado World Champ Konstantinos Trigonis, currently sailing an Exploder D3 A-Cat. He will also race coming F18 Worlds at Denmark with his long time partner Danny Paschalidis. Both will participate in Sopot A-Class Worlds in August, now reaching 100 entries:

May 25, 2017: New Formula 18 Rules changes proposed & to be voted soon.

Photo: Jasper van Staveren / 2015 Worlds - After more than 10yrs in the IF18CA World Council representing Arg and with our Worlds finished Nov 2016 I felt it was time to leave Class management locally along WC representation. It was without a doubt the most enjoyable and intensive +10yrs building, sailing and racing F18 ,also through Class work and with full promotion here in this web.

One of the things I always pushed within the WC was for the IF18CA  to inform duly and have transparent communications to the sailors. Specially formal rules proposals should be always distributed wide open.

Now the management accepted this request from some WC members (myself included back then)  and they have published proposals below.
Important to note that official text from IF18CA makes reference to a "Mast/Sail area"  rule change proposal that was blocked through voting months ago.
The proposed rule intended to define a fixed area  for main sails  leaving the combined 17m2 total of  Mast+Sail. The change was rejected due to the inconsistency on having only 1 builder mast complying to the new rule, leaving all others combinations out of the rule, handicapped in total area or with the need to modify current sails or buy new ones.

The IF18CA is a non profit public organization which is maintained directly by local Associations membership payments, which are then transferred to the IF18CA accounts.
President, Gral Sec and now an executive committee are the responsibles of administering those funds with some gral budget consultation and approval from the WC.
Reports on the spending is published every year and can be found here:

Now that rule proposals are public I can comment no problem my position on them:

Regarding rules changes below, the ones with more substance and clearly to read are the joined proposals from France , Italy & Hungary, two of them are based in my formal doc to the IF18CA WC back in April 2015, the formal doc analyzed the past, current and future of the Class and presented some alternatives to keep the F18 in the limelight.

Convertible F18 & expand Epoxy resin use
One of those proposals was to adopt and push for a convertible daggercase for sailors to be able to race and also foil for fun if desired outside F18 racing. Along this line of thought I also remarked that we should expand the Epoxy resin use, which is permitted in the Class since day 1 for building hulls, but only in combination with wood cores.

So, if someone wants right now to build an Epoxy resin & wood / balsa core  hull, he/she is allowed to race it 100% legal, no issues.
With many of the new Cats classes using Epoxy resins to add durability and reliability to hulls, basically more resistance and long lasting F18s, I saw no reason for the Class to allow Epoxy with wood cores, but not with PVC / Foam cores.

In the process using epoxy would allowed a more efficient  and durable use of  a "convertible" F18s, due to the high loads affecting platforms and hulls during flights.

In which way a convertible epoxy F18 would affect current class Status? well, only in a good one, as stated in my F18 convertible posts, an F18 could become the only double handed boat you'll ever need.
Participating in a still big floating class, and foiling for fun out of the legal racing without affecting your chances to swap foils and maintain a 100% legal platform to go racing at any given time.

Why convertible?
Right now I want to continue racing F18 for many years, but also would like to go foiling double handed. Do I have resources to buy two boats? Do I want to buy an Olympic Nacra 17 (beyond being a weapon as stated?  No, I only have budget if any , for one and custom assembly and I want to continue racing in a Formula Class.

So why not join two alternatives in one ? But based firmly on the F18 Class Rules to be able to race no problem? That is the basic idea which can only drives momentum for people to buy more F18s.

Rule compliant
On the rules proposals below by France/Italy/Hungary representatives  they analyze that a convertible platform will need  some additional trimming systems for the foiling mode, like additional clams cleats and sliders for the foiling daggerfoils and T rudder rake systems, the latter are already in place and allowed in the F18 Class:  for ie in the Nacra Infusion regulated castings.

In addition to the Epoxy expand rule, France/Italy & Hungary are proposing to removed the close rule wording, but I really see no issues having some additional clams, blocks for a main foil rake, as stated rudder rake system are already legal and non specifically permitted in the Class wording.

Ready to sail
The third proposal of this group includes a simplified or builder kind of pre certification of new F18 products, being boat, sails, mast etc. for them to be ready to race.
Read proposals for more details.

Below find the proposals above mentioned plus Dutch Class own docs published in the IF18CA official website with Gral Sec Don Findlay's comments.
IF18CA Official Proposals published at

Proposal – Rule simplification and changes 2017
Dutch proposals:
NED proposal Submissions #1-9 – WC Denmark July 2017 v.18052017 – This document gives an overview/summary of all 9 different proposals by the Dutch F18 NCA.
NED proposal #1 – WC meeting Denmark July 2017 v.18052017 – Text document with proposed wording with mark-ups which compares with the original proposal submitted in January 2017
NED proposal #1 – Appendix B – F18 Certificate v.18052017 – Excel document with F18 boat & sails certificate
NED proposals #2-8 – WC meeting Denmark July 2017 v.18052017 – For ease of reference for the NED proposals #2-8 this text document shows the proposed wording with mark-ups which compares with the wording of NED proposal #1

Italian/Hungarian/French proposals:
Submission 1 – To update the list of products entering in F18 hull construction to improve boat construction quality and reliability
Submission 2 – To develop the concept: one platform for a multiple program
Submission 3 – Removed with the abandon of the idea to modify the main sail/mast measurement
Submission 4 – The goal of this proposal is to propose new equipment stamped “ready to sail” from the factory directly to the customers in respect with the current class rules with no hidden or extra cost using an easy process for the customer: Buy it, use it!


Don Findlay's letter to the WC:
As Members know there has been much discussion about rule changes for the F18 Fleet. Council will vote electronically during June so that these matters can be finally resolved. Will all F18 sailors discuss with their National Officers and ensure that their views are taken into consideration.

Dear members,

I do understand the volume of paper work that is coming to you all this week. But we are discussing the future of our F18 Class. In the documents menu on our website you can find all proposals from the Netherlands and the Italian, Hungarian and French National Class Associations.

In line with F18 Constitution, I am asking the Netherlands and the Italian/Hungarian/French NCA’s to examine each of their proposals and see if we can amalgamate any to reduce the volume of voting.

I will be sending to World Sailing (WS) to ensure that any rule changes will be accepted by their Technical Committee, for there is little point in voting. Failure by the IF18CA to agree with their Technical Dept. will mean that the rules have to go to the World Sailing Class Rules Sub-Committee, which can be a longer process. If necessary and subject to their diaries, I will visit World Sailing on Friday of this week.

Once we have had agreement, or not, that proposals can be amended, then I will send out electronic voting forms which can be completed in four weeks. Constitutional requirements for voting will be detailed in the voting forms. I know that electronic voting is not popular with all members, but this is a complex task and leaving it to a Council Meeting simply would not work. This way, each NCA has time to consider and discuss with their members.

Thank you for your patience and support,

Don Findlay
Sec. General IF18CA

S1R report sent by Matt Bell from Outlaw Sailing , dealers of the S1/S9 in UK and the guys behind the concept of the S1.
Matt Bell: "When we set about creating the S1 we gave to Michele a list of what the boat needed to do, we created a target SCHRS rating and we asked him to work his magic. We wanted a boat that looked fast, went fast, was affordable, manageable on and off the water, simple but effective, sailable in 25knots, fun but most of all a race boat that performed on handicap in a mixed fleet i.e cats and

New Scheurer 'G7' 2017: A Step Forward

Images and video sent by Sandro Caviezel. - Lot too see in this totally new Scheurer G7 , 2017 Edition.
Where to start? Looks for the tillers.. they have implemented a similar solution like the Dna F1 to maintain them inside width, in pics  covered by back to transom tramp.
A new straight traveller as the D3s showed at Medemblik, but the biggest change is how forward the beams are set. Around 300cm from transom, which is where we draw with Arno for the FC.
Beams changed shape from the tubular to a more sharp edges, changing looks plenty, but functionality goes beyond the new position , they also have the ability to change the position of the mast step.

Sail is latest DS from Landenberger.
Click images for better view. Video above: small teaser on the new G7 upwind, the flight trim looks more like a Moth on its upwind stability.

Sandro is sailing with standard 9mts mast, and if new short masts can work in light winds as reported by Landy in Australia, then this new G7 with that shorter mast can become a real game changer towards the full foiling A. Lets see how they match against F1 and D3. So good to have Scheurer in constant development and pushing the limits. They have with Andy Scheurer and the Caviezel bros, Sandro & Daniel, an inhouse combined R&D / built experience as very few yards can aim to have.

Comments by Sandro: "We have new beams they allow us to put the mast on different positions on that front beam , that means mast can be place from 2840 to 3000mm (from transom),
2840 is for the standard mast , for the short mast you can just move the mast base forward what allows a longer base of the sail.

The boat performs. We did some prototype testing during winter time with a platform with different daggerboard cases:
1) Standard position
2) "40cm" position
3) Directly behind the front beam

It was interesting to see that the stability gains were just marginal with the daggerboard further forward but the performance lost was obvious.
so we just keep a certain distance from daggerboard to mast base and just moved the whole platform forward.

Another important information: The first boats are already ordered and the capacity of Scheurer Shipyard is very limited compared to other brands. Anyone interested in getting a boat early next year should get in contact with Aron ( as soon as possible.

GC32 Code Zero by 1D Sails

We use to see the giant code zeros for the D35s or Ventilos for Lake racing in Europe. At Balaton, in Hungary they also have light winds racing and there is a local GC32 team that decided to modify their factory deliver to equip it with a new spin pole and a code Zero. For the sail they called local sailmaker Marton Balazs from 1D Sails.

Marton has taken Ullman GZ legacy forward equipping the entire range of cats. Mitch Booth and Paschahlidis-Trigonis will be racing 1D sails in next F18 Worlds t Denmark.

Below a report sent  by 'Panka' from 1D sails on the work done for the Hungarian GC32 'RSM' new Code Zero to race at Lake Balaton, where the 2011 F18 Worlds were held:
"Balaton, in Hungary is the largest lake of Central-Europe and has a quite big sailing life. Among the activities there is a long time lake rounding regatta, the Kékszalag (which means Blue ribbon).  The

America's Cup 35 @Bermuda, 4 Days to Go: Short Film on Artemis Racing development

Photo above by Sander van der Borch / Artemis Racing -  This short Film is a perfect way to wait and see for the actual performance on racing for the points at the LV Cup.
Artemis offered the best media material on their series "Road to Bermuda", with this short Film presented by Altair Engineering  (Artemis Racing collaborator: , they have reached a new level on how to show and promote your work. Sailing itself & the America's Cup have plenty to give in terms of stories, personalities, tech and special images, this Short takes a good use them.
Footage displays a bit of the process they went through to reach current status quo, which is accepted by all, that Artemis is rather well prepared, fast  and in good shape for what is coming.

Performance development: 
For some months now I've been learning to 'develop', or better put: to understand how aero/hydro foils sections work, thanks specially to the great help and lectures of an US F18 sailor and Aeronautical Engineer, Sam Carter. What is interesting to see is how little modifications affects or changes performance/polars entirely.

In short film above Artemis design team put emphasis on how a "10th of mm" can do the difference between a good or poor aero/hydrofoil section or simple a fast or slow 'boat'. Nathan speaks on AC50s being literally airplanes, and for sure they are.

To reach the desired lift/drag ratio I'm making foils mods by bare hand, like sculpting each part of the foil beyhond the usual camber, thickness and other parameters. Once you identify how each part of sections affects its behaviour, you can aim to improvements with a "modify, test, verify" cycle.

Getting a computer to do all the possible mods and auto tests/results is no problem to achieve in current times and  the right resources and is one of the things Artemis engineers are doing (if I understood well, if not someone needs to implment it).
Additionally numerical & CFD tests must be validated on the water, and that is still the beauty of the design process. Those relying only theory, well , we already saw results in SF.

1 more knot
With all the OD framework affecting platforms, wings , dagger case positions and many other aspects, one thought months ago not much difference could be made with the little room left to play, but as we've seen thanks to MyislandhomeBDA plus reports from Oracle sailors for ie, there is a great gap among some teams in straight line speed only, not even to start analyzing systems  or TNZ cycling power and else.

I'm amazed on how precise the design process needs to be, if they speak of that 10th of mm final construction is even more critical, as small deformations on molds or final product might reverse the key "10th of mm" gained on the design 'table'. Good to see Brett Ellis still involved with the swede team.

4 days to go for the Louis Vuitton series.
Since we like Artemis and have deep respect for their work and how they reached this stage, we hope for them to encounter New Zealand in the Finals to have the very best challenger possible to race against Spithill's & his crew raw determination and Oracle unlimited resources, so we can have the best close match  possible.

Still nothing granted, we'll find out soon. Louis Vuitton Qualys Schedule:
