im staring doing detailed drawing now i just need a few dimensions so i can do this. thankyou

Hi Cameron, What Kiwi says is very pertinent. However, to answer your question you will need to make some very serious decisions. These decisions and the answers that you come up with will need to be included in your design brief. These are:
1 How much room do you have to store the land yacht that you make?
2 What sort of budget do you have?...even a home built land yacht is not cheap.
3 What do you intend to do with it after you have made it?...other than the obvious.

Will you want to sail with other land yachts in races etc?. If this is a possibility, then you will need to decide which class (class 5 or 6 most likely). Back to question 1. Class 5 yachts are quite large to store and Q2 are proportionally more expensive to build... cost of materials.

The last few posts in the general section of Class 6 rules will answer your questions on class 6 measurements or search Lake Lefroy Mini for the plans to that one OR open the Landyacht forum topic page and look at the right of the screen to Land Sailing Articles which has a topic on Land Sailing Class 5 specs or Pacific Magic Plans.
The other option isn't one I'd recommend as all of the hard work has already been done over a significant number of years by other people with much more accumulated experience and deeper pockets.This option is- Make up the measurements to; whatever you want to make them and then do the Mathematics to come up with the missing angles and lengths. (see your teacher if this is too difficult).

Personally I don't think this is the option for you for two reasons. The first is the time it will take and obvious lack of experience in making these calculations and making a landyacht. The second is that a recognised class of yacht will recoup more of your hard earned money(or your parents), if you elect to sell after the novelty wears off. Not to mention that less material will be wasted in making things that just don't work out...which means $$$$

Make a landyacht from the plans available and spend the extra time and significantly less money devising your skis for shallow water and soft sand. Even look at some kind of float with hydrofoils similar to the Hobie tri foiler which you could interchange with the wheels for use in the water. Have a look on youtube. Nick

have to agree with alot of what 307 has written.
When trying to work out a measurement on something this small, you can even try drawing it full size on the ground. I do it all the time, but hes right, the maths your asking is pretty basic, talk to your teacher

Yep, lets not lose focus that this forum is to promote the sport and encourage people to get into it!

Cameron's picture only has the length of one of the right angles and there's no indication that they are of equal length so unfortunately even Pythagorus won't be able to help him with that one, hence it is a valid question! That said I do appreciate your intentions 307.

Give a man a fish and feed him for a day, teach a man to fish and feed him for life... Either way you have to tell him fish exist!!

A bad days fishing is always better than a good day at work!!!

and yet i live 400kmfrom the beach and probably go fishing more often

sounds like a good idea. reading , understanding, and following plans and instructions, and creating a piece of work to a good standard is surely the place every young designer should start. From that they learn the process of creating something themselves from scratch.
I know that from comparing notes with other builders on this site ive learnt better, more accurate, and simpler ways of doing many things

so will this one be good just need to check before i buy it

and another few things what materials do you use ? tube mild steel , angle mild steel? and where do i buy mast and boom from?

Cameron, this is all starting to go around in circles....
Please read again the construction of the Lake Lefroy Mini

All or most of the questions you are asking are answered in that thread on the forum, as you are are in year 12 and will be next year in the workforce or in tertiary studies a lot of things in life you need to find for yourself.
Cameron as this is your assignment and a major piece of school work in year 12 you need to do the work.

Try the search ....it works well


Splitpin.... as a parent of 3 past Yr 12 students, their respective Schools expected the students to do their own homework/research as it is an important learning tool for the future.

Not being harsh just realistic!

[]apart from windsurfer masts i would not know where to source one,so let us all know where they come from,and i am not a student
[

recycling centres, road side rubbish days, scrap yards, windsurfing and sailng shops,aluminium shops, sailing websites, curtain shops, hardware stores
............quokka(WA), trading posts, for sale sections in newspapers. If you see an old windsurfer in a driveway, knock on the door, put up a wanted notice at the corner shop, or supermarket. yacht club clearout days.....
G"DAY splitpin

thats always the problem when you have no name, and no place we can use as a reference. If a person at least puts a state or town in their profile we can assist with more direct links, even in scotland , nevada ,montana, chile, namibia(yup)Libya, or a desert in India, we can help

Thanks for putting up the topic posts Gizmo...I haven't come across the mini boom post before.
