I am more than happy with the mini dimensions, just that other contributors have suggested that they should fit Class 6, so I wanted to be totally clear.

Yes I see where this comes from, but are the class 6 rules being used?


There has been some mention of changes which seemed to have occured under the cover of darkness by a group that doesn't want to be open and transparent.
My personal thought is untill there has been proper and true transparency, any existing rules MUST STILL APPLY and not changed by "chinese wispers" and then passed on by word of mouth.

I was unaware that NZ had class6 rules... how do these compare to Aus class6 rules?

Lake Lefroy Mini specs thread..
www.seabreeze.com.au/forums/topic.asp?TOPIC_ID=39791


Now, not to deal with all the above, for obvious reasons.
NZ class 6 was put in place in 1984ish (and nothing ever happened except for a year 13 school project, about 20 or 30 built). My memory is hazy, but;
45 sq feet
1.8 metres wide.
Pocket luff sail, no more than 120mm laid flat (same as class 5)
Max wheel size (I think) 400 by 8.
Seat belt when underway.
I don't remember a length being included, designers choice?
This could erroneous, it's a long time ago. The sail area and width I am relatively confident, the others were discussed. At the time there was a commercial yacht called the Boomerang which the rule were framed around. This is DEFINITELY NOT TO BE USED AS THE RULES, and I suspect that they have been dropped from the NZLYA rule book, if such a thing still exists.


This is copied from the NZLYA Rules of July 2000


and this is the Aus class 6 rule Brian wrote in 1985. We understand that the Aus rule is still current which was confirmed recently.




and then this came in from Dave Webster the other day.



Then there is the LLF Mini rule, length, breadth and seat belt. I love it!!

Thank you Cisco. Those NZ class 6 rules are correct. As far as I know no one ever built one, so it just shows how popular they were. Then Paul Beckett came along with his little Blokart sized yacht and they sold like hot cakes as they were easy to transport and easy to sail. The NZLYA have a "Mini class". The size was based on the Blokart trolly size. There is no mention of wheel size either. I cant locate the document at the moment but I shall hunt them out. My Mini will fit both NZ Mini & LLMini specs.
Anyway... Stop talking about it and start building!!!

That comment was not ment for you Cisco. Your mini looks great. Great workshop too. Tell me, are your minis built to the maximum 1500 width? My plans were to keep width to 1300 to 1400 to keep proportion (1:1.25) similar to my class 5. What are your thoughts on that?
I guess I could make it adjustable to experiment with that.

I reckon that Paul Beckett has got it just about right. Ive built a couple of smaller yachts( youll hear me refer to microyachts)but I have found them that bit too fragile to sail, they slam dunk you , they are too light to throw around on a tight course.
when they capsize you cant help but get a knock off the ground. with your taller wheels you will inevitably smack your head on one
In Nappy rush , I was able to drift steer into the really fast downwind marks and reverse the airflow on the sail so that you could come out of the turns without loosing ground downwind.with a smaller yacht your just too light, and would invariably capsize .
keep in mind that packed down the only bits that were longer than 1m were the boom,sail and mast sections,
last time I saw a Ludic I think that it was wider than long. they go like the clappers, so maybe the ratio rule falls down as the yachts get smaller

So just a question about the Mini rules from Dave Webster, are these the rules that were passed under the cover of darkness and so the Pheonix land yacht (the one Dave builds and sells?) fits into an Australian class?

Gismo are you a fully paid up member of ALSA if so it was your delegates that passed these rules so what is your beef.

In the time (approx 1.5yrs) that I have been contributing to the Seabreeze Forum not once have I claimed to be a "fully paid up member of ALSA". I have also been very open in the fact that Im passionate about the sport of Landsailing and that I have a proven track record as been active in the formation of ALSA.
I left the sport to raise a family, and until I found the Seabreeze Forum
I assumed (wrongly) the sport had continued to thrive.
I was and continue to be disappointed in the actions of some. A considerable amount of time and effort by many people was put into sport in the early days, to see some areas of the sport in such a poor state disappoints me to say the least.
To imply that because Im not a "fully paid member of ALSA" discounts me from expressing an opinion is highly rude and offensive and believe me at this point Im offended.

All I have ever wanted for the sport is for people to be fair, open, honest and accountable!!!

i am sorry if i have offended you,but i feel that those on the committee to look after the sport are making those decissions the best they can,and must have reasons unkown to us as to why they made that decission

A quick search gave me this www.nalsa.org/Minirules.htm
A second search on seabreeze gave me this
Australian Land Sailing Association (INC)
Constitution
2E. To establish and maintain contact with overseas land sailing bodies for exchange of advancements in the sport and to encourage representation at international competitions.

1+1=
Just a thought
maybe you should give ALSA some credit for trying to do something to bring Australia into what could become the world standard instead of fragmenting the sport. A lot of people have been complaining about ALSA, they give us something to consider and the first comment is not what I would call constructive

Paul's advice was "Stick to the Plan" which I did and it worked. I haven't even run a tape measure over it to see what the size result was.

You could be right, I ran my class 5 shorter (2.25m)for a year or two and it just made it quicker on the turns. Some of the european class 3s look to have a "short" ratio. Could anyone throw some light on this design question for me?

Just give Gizmo a few more minutes and he will probably post a web link to a page that will be relevant.

OK just got in from mowing... at last the lawn is green again.
You have lost me on this one cisco, the only mention of size I can recall for the LLMini was in the building link

I am well aware of the LLF Mini maximum width and length.
I intend to go maximum length, but I,m not sure if maximum 1510 width is the best platform for performence. It may work for landyachts with stayed rigs as they are pulling on there windward axle but unstayed yachts behave quite different. All the action is working on the leeward side of the frame. If the triangle is too wide the yacht could tend to crab and create a lot of wheel drag. Any opinions on this subject would be most welcome.

Clemco, I don't think you are quite getting the point or say philosophy behind Paul's design of the LLF Mini. Click on the link to get it from the horse's mouth. It got buried in the forum and should be made a sticky next to his build thread.

www.seabreeze.com.au/forums/topic.asp?TOPIC_ID=39791

Edit:- This is the same link that Gizmo put in his post above.

You are mentioning a "maximum length and breadth" for an LLF Mini. The LLF Mini has a length and breadth which is it's maximum and minimum. I am not saying "Don't experiment."

What I am saying is that if you digress from the design parameters it will then be a "Clemco Mini".

With "Diablo" I stuck to Paul's plan except for a couple of very minor construction details which were easier for me to do than the way he had done them.

I am very pleased with the overall result and I am hard pushed to think of how it could be improved without designing a whole new yacht which Paul has done since then. The result is "Nappy Rush".

One little variation I would suggest is having two bolts holding the seat back support in it's socket. The sheeting pulls the support up when you pull it up hard. It is annoying to the pilot and will stretch the socket to a bellmouth shape eventually.

One of the beauties of the design is that the rear wheel base can be varied by drilling extra holes in the axle extension or even having different length sets of them.

I hope you are going to take plenty of photos and post them. I feel sure that you will do something different that we will all learn from. Cheers Cisco

Just to clarify a few misconceptions about Phoenix Landsailing.

A. Phoenix Landsailing built the "Swift" to the American and New Zealand rules because of a marketing strategy to sell Swift's to the US landsailing market and at the time these rules where current.

B. Phoenix Landsailing built the "Swift" to the American and New Zealand rules because we are a Pacrim country and at the time these rules where current.

C. Should we of modified our Ludic's and other Seagull landyachts to fit those so called class 6 rules?

D. We have only wanted the sport to move out of the dark ages in Australia whether a person wants a Blokart, Lefroy Mini or one of our products.

In my opinion1510mm is just about right.
realistically the size of the yachts is getting too small for stays. but the width/length is just nice.
trust me

OK, I am happy with that. I will post a plan in a few days.

I also would like all the bush lawyers & politicians to keep off this thread, thank you.

OK so I am a clutz!
I was looking for some dimensions for Nappy Rush AKA Mini Magic!
I had not crossed over enough to realise that there none for that! Explorer is there, just not what I was looking for.

CLUTZ! now theres a good name for a mini!
I left the critical dimensions off Nappy Rush, so that people would have to THINK about what they were doing rather than having the luxury of all the plans and instructions laid out before them
sonetimes you have to do the hard yards to get out front!
in fact Ive probably let too much slip already. could it be that my reign as Australias second greatest landsailor could come to an end

I never finished one before the "improvements" were in my mind! In the heyday it was a new one, sail it, do well, sell it, build a new one about every 2 weeks.
That was when I could score points with the management by putting $$$ INTO the housekeeping from building sandcarts!
Then of course came the production yachts so I had to be a bit cautious on having a yacht that went better than what I was marketing!
