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

If you are thinking the curve of the luff causing creasing the answer is it doesnt
because the curve is very gradual and the stitching takes it up as it is sewn on to the sail
The luff pocket is usually made up and sewn down the open side about 20mm
from the edge the two edges are then fitted on the sail one on each side and the
whole is sewn together The curving is cut on the sail first
Hope this makes sense
bejay, I assumed you have seen this thread on Tyvek sails?

what was the booK . Landsailing books are rather rare.
I only know of 4 published books on the planet. they would probably one of the rarest type of books ever.
And my wife wrote one of them 
there is only 1 box left in the cupboard (50 copies) out of 250 printed.
I believe Andy Parr keeps his in the Attic, The R/C book is well out of print and the Belgian History book was a limited edition too.
Yes Gizmo, I did read that thread thats what gave me the idea, but I couldn't get my head around the luff pocket, but Hiko put me straight.
Landyacht, It wasn't a landyachting book, it was "The Sun Annual for Boys" 1976 it just had a five page article on sand yachting, below are the pages.
That's great Bejay, That is a good start to your career as a Landsailer. Your next effort will be to build your own as the Bug has Bitten[}:)]. Who knows you may even challenge Greenbird.

Interesting looking at the number of clubs in existence on that book.... less than half that number now, that I've found in the Britain.
Cheers? Col
Open yer Waxy Ears, Cloth Ears. The idea was to demonstrate Broke Bicycle Spokes. You know Broken Spoke Wheels!!!
I can't put it any plainer for the ill educated.

PS; Oh! And a little Light Heartedness. You know FUN! That is F-U-N
What weight of sailcloth would you use for the mast/luff pocket? I've got the two R+J sails that I can squeeze a bit of life out of if I just add new pockets.
Cheers Col
Col,
Check the Cloth in use and replace it with similar. You Sail Maker will know what it is and what is suitable.
Ron
Unfortunately Ron my sail maker is .....me! And what is left of the originals doesn't make the slightest bit of sense as it's the grippiest stuff I've seen on a sail. Sort of rubbery! So it's hit Fleabay and buy up some cloth. So far found weights at 5, 6 and 7.2oz and various materials but mostly dacron at 1.1m wide and buy by the meter. Just sorting out a sewing machine as it's cheaper to buy one and DIY for the 3 sails I have than pay for even one sail to be sorted professionally.
Cheers Col
5oz dacron should be fine for the pocket The load is spread along the whole length
Double it at the top and bottom with a 50mm hem
Good luck with the sewing machine Go for rugged rather than fancy
Having said that a fair bit of sailmaking has been done on my wifes light domestic
not without some interesting language I would have to say
Col,
I will adds something else that has not been mentioned to you at this point BUT has been discussed in the Forum. Double sided tape ( A thin Clear tape) Not particularly strong under tension by itself but once applied is very grippy. Some use that from El Cheapo shop or else stationary outlets. I prefer to get it from a sail maker and use 12mm/1/2" wide but it can be bought in different widths. The tape when applied serves two purposes one it holds pieces in place for stitching and it also helps the integrity of the finale sail. Try tearing stitching with and without it, it works a bit like rivets or nut and bolts holding two pieces together the Bolt/Rivets takes a lot of strain but Friction is one Hell of a big help and all. If you've ever taken a sail apart at the seams you will get a fair idea of what I'm saying. Least ways that is what I've learned.
Ron
try and cut some long strips from that big offcut on the windsurfer sail you chopped.the weight of that would be fine for your yacht
Thanks guys. 5oz dacron it is when I get to sorting the R+Js. I've got 3 different types of double sided tape to try out - one of which claims to be external use and thinks it's a glue apparently. As for using the bits left over, some pillock has cut some batten pocket reinforcement bits out of whats left
Sewing machine (I got about 80mm by hand and once the swearing had stopped, I decided sod the cost, get a machine) is looking like being a Jones semi-industrial one. No oil cooling, no table but all metal construction.
Cheers Col
