Thanks Promo Girl! I'm still a little confused though. I'll have to re-read all of the class specs, but it seems to me you're saying the "unlimited" rules of class V will cause the $ arms race and yet the "limited" rules of class 6 will do the same thing.

To me, it looks as if class 6 is more of a "small Promo" than a "small class V" and therefore could potentially share the success of that class for all the valid reasons we've discussed before.

What have I missed to throw me so far off the track (I'm sure there's something )

BTW that will be very interesting if anything comes of the Olympics meeting!! That definitely deserves its own thread

STill too many rules!!!!!




I bow to your experience Paul. In my proposal I tried to make it as simple and succinct as possible while covering all nescessary bases. Only way I can see to reduce the number of rules is to reduce the number of bases.

Should it come down to :-
1. Length.
2. Breadth.
3. Height.
4. Sail Area.
5. Safety.
???? If so, how definitive are these items to be. Should a proveable building budget be applied to encourage amateur construction?

Given the information you received from Eric Engelbrecht of FISLY regarding restricted use of non FISLY approved designs, it would seem there is an obligation on the part of FISLY to publish a set of FISLY approved class 6 specs if in fact they intend having a class 6.

If they do not intend adopting such a class, it would then be up to say, ALSA to publish and class 6 would then be an Australian peculiarity in land yachting.

Further to your conversation with Eric Engelbrecht, it appears the only FISLY approved Promo 5's will be those built by commercial manufacturers in Europe and duly marked with the CE symbol. Is this the case?

Maybe it is time Australia developed a design and manufacturing protocol and certification process and applied a CA symbol to it. That way we might stem the flow of substandard Chinese products that are flooding the country right now.

I knew i did not explain myself well what I meant was that although class 5 has rules they are such that they mean that construction needs to be via medium to expensive materials. To win expensive.

Promo has rules but the rules dictate no expensive materials (ie wheel barrow wheels and dacron sails with only 5 battens)

Original class 6 rules - almost completely open. Cheap - medium and expensive materials allowed including wood. Wooden back axles can make for a very interesting and quick yacht.

Recently posted class 6 rules - stipulating construction materials (disallowing some of the cheaper options) back to medium to expensive materials - just like class 5

Does this explain what I am trying to say better?

I feel this could work.

Whoa..a little of track from what Paul meant. He is talking about what is happening in Europe with FISLY endoresed events. Event such as the Pacrim are currently ourside FISLY. At non FISLY events such as the Pacrims or some other open event you can do as you please however if at some stage we wanted to run a worlds here in Australia one day it would need to be under FISLY's banner and by there rules.

Not necessarily, a home built Promo would be allowed provided in conformed to specs. It is accessing the materials that *may* become problomatic as it presently seems that in Europe that some of the materials *may* be only available via commericial manufacturers, however with some questions still remaining on translations and interepretations this is not 100% certain.

FISLY is not interested in class 6 - This is just a quirky Australian thing. There is talk about Blokart becoming a monoclass with FISLY (just like standart) however I think at the moment this is just talk.
It is up to ALSA as the governing body in Aus to lay down the rules for a class that only exists in Australia. Any changes to class rules should be done in an open and accountable manner with time for discussion and debate by all interested parties and via the correct procedures at outlined in the constitution...off soap box

Now thats a scary thought!

Right, so the problem is we can't build them out of wood?? Nah, just kidding. Obvioulsy I'll have to re-read all the specs, I'm sure that will make it clearer to me, I missed the part about using expensive materials. I just thought you had to use round square or rectangular metal tubes.

Let me re-read the specs for all classes when I get a chance and I'll stop asking such silly questions... promise!

Hi Hills, I am always going back and re-reading specs, confusingly there are various editions around too so it can be confusing. I do not think your questions are silly either. It is good to question, thats how we all learn

Thanks Susan,

It looks like we need to get our act cleaned up here in Australia before we take any big steps onto the world stage.




Yes we can learn from our overseas friends however don't be mistaken they have not got all the answers either! But yes I think we do need to have a good look at ourselves....enough said...those in glass houses

No you cant build it from wood. ( Promogirl is trying to find a photo)
The wooden chook was indeed built from acrate and was as fast as a club 88. The combination of a deep wooden hull ,springy rear axle and a rig that lays over as the rear lowers is exactly what you need to achieve in a class 5. Bill Finch achieved this in 1987 and that was the end of what should have become a massive leap in development.
With talk of the Aussie cl 6 coming back I had been accumulating materials for a new yacht but with the new rules it is not to be. The best rear axle timber is old Table planks of huon pine or even better King Billy salvaged from a tip at no or little cost adds to the achievement.

Stevo bbb, and Landyacht
I'm with you guys, way to many rules for me, i just going to stick with the blokarts, easy rules to follow, heaps of people have them now and more and more events happening regularly. I have heard they are starting up a forum on there Aus website, should be good to chat with other blokarters around Oz.

C U in Mackay for the blokart titles.

I had heard that a new class was passed by ALSA. Been a while since I have been to the forum and mow read the new class rules. Seems to me to be close to a class 5 not so much a mini yatch. Is there going to be a mini yatch class?

I was doing a google search and found this site about class 6 land yachts.
I’m Brian Reynolds and noticed the original specs I had recommended in 1985.

The reason for Class 6 was that the ALSA regarded class 5 to be “The Race Class”
Class 6 was to be an “open class” to encourage newcomers, women and children to the sport as Class 5 was getting pretty full on.
Another reason was to have a yacht that was simple to build, looked good and could be sailed in shopping centre car parks with lots of public exposure which in turn feeds the Class 5 with completive sailors.
Referring to the original specs (posted on this site on 13/12/10) the design principle was simple…

1. Max width 1.8m
This was to enable small yachts to be easily transported and stored even the “Free flight” built yachts to fall into the class.
2. Max length of 2.25m
This was to level out some of the yachts, as many different wheels were tried from small sack truck size to 20” BMX bike wheels.
3. Max sail Area 4.25sqm
4.25 sqm was found to be safe and sufficient for learners, women & children
4. No moving seat
This was to simplify design and for safety
5. No covering OVER the pilot.
This to provide little chance of being trapped inside a yacht (as some fragile enclosed designs were starting to emerge on paper) like mini “sanderlings” again for safety
6. Round section mast only
Some fancy designs of wing masts were also being thought about which again would make the yacht design complex and going away from the original concept of class 6
7. NO sail fairings in or on the sail
The idea of a sail covered foam shape was also thought about thus going towards rigid sails.

It’s actually a pity it hasn’t seem to have taken off as it has HUGE potential to promote LAND SAILING
The design is so open to good clever design and use of materials such as moulded fibreglass, Aluminium, Plastics and good sail/ rig design etc, to make some GREAT yachts.

My personal thought is that if you were to build a yacht to ALL of Class 6 MAXIUM specs you would probably have a very easy to sail “SLUG” ……
CHANGE some of the relationships of measurements to each other and with good design and attention to detail you will do well ….

I hope this helps a little with why Class 6 yachts evolved……

G'Day Brian, welcome back to land sailing we had all thought you had dropped of the face of the earth the last 15 or so years. Glad to hear you have found us. If you search back though some of the earlier sea breeze posts you will find reference to your 1985 class 6 specs. We were all happy to resurrect class 6 around those original specifications however it appears ALSA has changed the class specs in the last month to a much more rigid set of rules that will not allow some of the existing commerical yachts.

I am still looking for a photo of the wooden chook, Bill Finches amazing class 6 yacht circa 87/88. I am sure you to would have some photos hidden away of some of the yachts we used to sail back then?

Anyway glad to have you back, are you sailing at all at the moment?

Hi there, Im still looking for some of the older pics altho i know i dont have many(if any at all) of Bills yachts.
I was out of the scene by 1988 and actually never saw it (wooden chook)
Im actually surprised that not a lot has changed in the yacht designs apart from "Phase 5" ......
Maybe the sport is starting to look a little old and tired (my personal opinion)compared to many other changes in similar sorts of sports have had in 15 to 20 years.
ie. Sail boards, Bike racing, Water sailing, even olympic runners, swimmers have gone hi tech.
Im very certain many people wouldnt be inspired with the design of 20 year old cars these days.

Ditto, my beautiful '84 Fairmont with a Webber carby gets exactly the same fuel economy as an 06-07 SV6 Commode with it's whiz bang computer sitting on top of a 150 year old engine concept.

And does it with better comfort, dignity and STYLE!!

Well I did say we had not seen you in 15+ years, turns out it was 20 years...gosh where does time go.

Yes there are some yachts that have not changed much in 20 years however if you
take a look at some of the snaps from the world champs the class 5's are not old or tired looking at all and when you look close quite high tech a big change from the old phase 5's and lots faster.

You might also want to look at the snaps of Pauls mini yacht, very sleek with the fibre glass seat. Now they are fun yachts to sail. This is only the very begining of this new type of yacht. Paul has barely started experimentingwith the potential of this size yacht. I know because I have heard it all again and again and again...

Also you might want to look at the world champs website at the promo class yacht, although the specifications mean that the chassis may be similiar to those of the 80's and 90's the sail design has improved markedly and they race very very differently to our old yachts.
Although today many yachts are *designed by computer* the finishing touches and the feel of the yacht when sailing has evolved in part due from the experaince of pilots who have sailed this class form 20 -30 years.

You will see if you look at the photos that your sandpiper design was maby 20 years ahead of its time
