AMOUNT OF CAMBER

HHRICK — Fri, 18 May 2012 23:31:42 +0800

Hi--new member here---
Anyone building thier own landsailer sails? I am setting up to design and build my own sails. My first sail is going to be mainly X-Ply momofilm and some 4 oz dacron. Any experience as to the amount of camber and the position the maximium camber should be from the luff sleeve? Thanx!

How tight should it be?

Nikrum — Sun, 06 May 2012 08:59:00 +0800

And should it be the same at the top as the bottom Mast pockets is what I'm talking about. When I knocked together the sail for 'Test Bed' I just took the max spec size from the Class 5 regs which I think was 140mm flat. I've just spotted an article explaining windsurf downhaul about the bottom of the sail being the 'engine' and the top the 'exhaust'. And that the bottom needs the battens close to the mast to get the correct shape but away from the mast at the top. Is this correct? Should I tighten the pocket to be close to the mast (not too tight to stop easy movement) then run the stitching straight along the pocket or should I follow the mast's taper Thoughts from the experts please, as currently the sail is like an on off switch, literally nothing happens till the wind picks up then it's off like a rocket

what to do with this!

http://www.seabreeze.com.au/img/photos/land_yachting/5649620.jpg

It's got a panel blown out at the bottom, and a few small pnctures. Also the bottom two battens are missing. generally i'd say it's well used!
http://www.seabreeze.com.au/img/photos/land_yachting/5649618.jpg

I'd like to end up with something bigger, (around 5m) for light wind days which we seem to have quite a lot of lately, (i know making this a big sail will change that!)

Is it worth the effort?

New Sail to cut.

mrsquish — Tue, 13 Dec 2011 14:08:01 +0800

So I'm finally taken the plunge and bought a "new" sail for the landy, and will be needing some advice on how to cut down.

This is the sail, http://www.windsurfing.kasail.com/archive/2000/kaos.html in a 6m.

I'm hoping to be able to measure exactly where that will come to on my mast of ~4.3m on the weekend. But just a quick question on luff curve. How exacly is the luff curve template done? Do I attach a rope to the top of the mast to the end of the boom and sheet it in all the way, then mark the curve of the mast on the template?

Cheers,

Adam.

downhaul and reef points

Gizmo — Sun, 27 Nov 2011 07:03:24 +0800

i think i have half a clue on the concept of downhaul and reef points (i probably don't).
would one of you boffins like to take the time to explain the merits and fine points on (heaps of downhaul) and i would love to know how the pulley's are numbered. ie 3-1 haul. which pulley is the 1, which are the 3, do doubles change the ratio??.

Telltails - how many and where?

colk2004 — Sun, 27 Nov 2011 06:27:37 +0800

I've been trawling around for a definitive answer and so far they're all slightly different. I use them a lot on the Seagull MC2 and find them very useful. I've seen percentages, measured distances, one above the other on different sides (which is correct), even different luff placements. Help.

Cheers Col

Worth keeping an eye on - Cheap sail bits.

colk2004 — Sat, 26 Nov 2011 19:24:39 +0800

Unfortunately I guess with shipping costs this will only be useful to Republic of Ireland and UK members, but I've been picking up a few bits now from http://www.sunset.ie/ or more exactly their http://www.ebay.co.uk/sch/sunset.watersports/m.html?_nkw=&_armrs=1&_from=&_ipg=&_trksid=p3686 ebay shop. They have picked up a load of the Neil Pryde Irish factory liquidation sale stuff. Just bought 110 batten ends at 4p each, and previously had 7.5m2 of sail cloth of them. Currently selling 1000 battens with ends for �342. But all the cheap stuff is getting dumped onto EBay, worth a punt.

Getting more upwind speed

landyacht — Thu, 24 Nov 2011 20:05:29 +0800

On my A Class Cat (see avatar pic) I have put on a new and much fuller sail to get more off-wind and down-wind performance. As expected I have suffered upwind, to some detriment.
Naturally, it needs to be more flat upwind and needs more prebend in the rig, (10m of CF wing) but I don't want to lose shape by cranking it up too much and going back to where I was last season with my old sail.
I can really feel the drag upwind and against other boats it seems 'laggy'. Lots of downhaul/Cunningham helps but the sail gets stretched so much down the luff when you really crank it on.
My reason to post this?
Landyacht sails seem really flat and generate much higher apparent wind speeds, being an upwind machine that they are. I am hoping to get some advice from the LY speed freaks out there to get more speed out of my Cat, from anyone who can suggest something.
Any suggestions most welcome.

500 Denier Polyester?

desertyank — Sun, 16 Oct 2011 17:29:32 +0800

Hey Lads,

Speedline Textiles have some seconds 150cm 500D SOLUTION DYED POLYESTER FR PU COATED. It's seconds because the backing is comes off easily, but they're selling it at $2.00 a linear meter.

Two questions,
1. how do you reckon this would compare to Blue poly tarp as a sail material?
2. If it is suitable for a sail material, and I have to buy a large amount, is there anyone interested?

I'm not sure at this stage if I'm able to get any of this stuff. I've contacted them and they said they'd have a look if they had any small rolls.

Here's the link : http://www.speedlinetextiles.com.au/Specials.htm

mast luff pocket

colk2004 — Fri, 14 Oct 2011 20:53:48 +0800

Hi I'm new to this forum, have wanted to build a sandyacht since 1975 when I saw a diy design in a book, I recently found said book in an attic clearout so the idea of building my own came back, I've been around most sections of the build forums and am able to understand most of the buil criterior but as I'm building on the cheap I was thinking of making a Tyveck type sail, the question is how do you fix the mast luff pocket to the sail luff without the mast pocket creasing.

P.S. anyother landyachters from the UK what sort of wheels do you use.

Thanks in advance

Must be something worth saving in this lot!

landyacht — Tue, 04 Oct 2011 20:04:26 +0800

Well this is what I've dragged together so far to get a sail out of. First is my �1.20 Ebay purchase.... all 9m of it. I'm guessing this would need a lot of work to get it sorted out?

Just picked this up today - bit of a conundrum. Right hand side.
/Img/Photos/Land_Yachting/5206749.jpg

Left hand side...
/Img/Photos/Land_Yachting/5206751.jpg

Ta da! Both mast sleeve/pockets have been cut in half and stitched together. Also some holes in whats left of sleeve. Has some ally plates riveted to it so it wraps round the mast and then is strapped together to form one heavy sail. So it would need the pocket cutting off and a new one knocking up out of something (twice) also no battens, and a load of holes to patch... but it is a 5.5m class 5 sail.

Any thoughts on what is the best way forward and please ...

source of double sided tape(probably WA only)

Nikrum — Sat, 17 Sep 2011 08:33:49 +0800

after running out of cheap double sided tape a while back , i have been getting it from the sailmaker that has been helping with our mini sail designs, but I cutting into his supply, and its not as supercheap as it could be .
today whilst shopping for fibreglass tape for a "special secret project"I accidentally saw a box labelled 48mm cloth backed doublesided tape.
and it was too, massive 50m rolls that can be sliced into whateverwidth I need. its the same brand as the sailmakers stuff, really sticky and tough.
The brand is STYLUS TAPE. I paid $22.00+GSTat an Amazing place called ATOM SUPPLIES, a big industrial supplier in kalgoorlie.
I believe youve got one Chook!!!!!

suitable cutting down sails on seabreeze

landyacht — Fri, 16 Sep 2011 20:10:28 +0800

ive had a couple of enquires this week from people building minis, who are asking about suitable sails, so I went through the seabreeze buy and sells in the under $100 price range. I mainly looked at surf sails under6m. If your a windsurfer and have anything that would suit for sail, dont be shy and add it to my find list

Revisiting my landsailer after 10 years!

mrsquish — Wed, 07 Sep 2011 20:33:44 +0800

Hi All,

With the help of my father and other friends I built a landsailer when I was in my early twenties (some ~10 years ago now). It is predominantly built from aluminium scafolding tube, with a 5 meter aluminium mast (with zero rake). It's roughly 1.8 meters wide and 2.5 meters long.

When I had it going I used a recut windsurfing sail, which I've still got (and would probably still be servicable) but it has seen better days and I'd like a replacement.

So, down to the questions!

Why dont people get sails made specifically for landsailing?
Given that they're almost flat, why don't people make the sails themselves?
With a non-curved mast like mine, would a recut windsurf sail ever perform well?
Has anyone tried creating a hybrid foil with a aluminium frame like an ultra light and sail material?

Any advice as to which way to go with this would be greatly received.

Cheers

Adam.

Help needed to make a custom sail

Nikrum — Fri, 02 Sep 2011 10:01:23 +0800

My local sail maker has told me he will make a custom sail for my mini. Can anyone help me source a plan or layout that I could give him? I was thinking 5.5 m

Thanks

Hey guys,

Has anyone here organised freight for a windsurf sail? The battans seem problematic as the maximum length that Aussie post will accept is 105cm. I ask because the pickings for larger sails in Vic a bit slim at the moment.

Cheers,

Adam.

storm sails for silly days

Nikrum — Wed, 17 Aug 2011 21:07:17 +0800

in the last couple of weeks Ive been chopping up some windsurfer sails after not having the right sail on a realllly windy, perfect salt day.
most of them started life as surf sails in the 4-5.5m range, these sails tend to have a very similar profile,luffcurve anddepth to the sails we would call a "landyacht sail"
the biggest is only a 2.5m down to a 2.0m
I tried to make sails that needed a short mast and a longer boom, the theory being to have less heeling force , but still get some accelarating power from the long foot. here are the results

The free 4m mini sail, with conditions

Test pilot 1 — Mon, 15 Aug 2011 22:06:36 +0800

TP1 and i just finished recutting a interesting windsurfer sail into a 4m mini sail. It features 3 cammed battens, and the cams have rollers on them so you dont needd mast rotation.
the top is very fine so the mast needs to a neat fit. we didnt have a mast to suit, so ive decided to give the sail away for free.................but you will need to bring a mini and a boom of at least 1800mm as well as a 400cm RDM skinny carbon mast to lake Lefroy to claim your sail. you may have to cut down a 430 or a 460 but thats your problem you will also need some small pulleys to build a multi down haul as the sail will need about 4:1 at least.
first in best dressed, and no i wont freight it as i want to see it sail.
hence you have to bring a yacht

Yet Another Sail

Nikrum — Sat, 23 Apr 2011 15:17:13 +0800

Reply posted by Nikrum...

Points noted Nebbian,
I will Tighten those battens next time I have it rigged but the Down-haul tends to right itself under Fully Sheeted In. There is a tad of slack in the Head as well but it seems to correct itself as well under pressure. The Sail seems to have a greater Torque Moment on the Rear End, particularly noticeable on wet Tarmac but hopefully that should drop off at higher speeds as it seemed to show up under gusts. We shall see and I will keep this Post open for updates.

Well there is an upside to the AUS S02 go to

Oh! Poop! Well I literally did as you suggested Paul, I cut the Luff Pocket to exactly parallel. It doesn't quite work that way. Starting at the top I measured the Half Width as it is folded in half and transferred this measurement down the pocket and cut as I went. Hm! Perhaps I should see how it looks wrapped about the Mast Base.. Oops! Cart before the horse. If I sew that lot together it will be a tight fit I think. Because of the design and method of trapping the Sail Head at the Mast Top The Luff Pocket is fairly narrow and I didn't take this into account and allow a little more room at the bottom of the pocket to accommodate the mast base. Oh Well! I will have to make a new Pocket I guess..

that is lookin so good. I think you will find on future sails that you dont need all 10 layers as we are not straining the sail as much as the windsurfers do. buy your mum a nice bottle of wine as a thanx , or dinner, , and flowers of course
