First time landyachter looking for material advice

Hello, I am very new to land yachting and figured this would be the best place to look for advice. I have been looking through lots of forums and it has helped me to start off on my yacht, but I could do with some pointers.

I have a very small budget to build my yacht (£200) so I was wondering if anyone could suggest inexpensive materials for building the sail (I am opting for a soft sail) and give me advice on what I'm going to need to do it?

Any help at all would be greatly appreciated!

if you cant find a windsurfing sail , look for really big cruiser sails that can give you some big lumps of sailcloth
ps welcome aboard also

Look for a windsurf sail that will cut to the size that you want eg 6m to finish 4.5 / 5m. You also need to get a sail that is the right shape and ideally as wide a material panel on the luff as possible.

Thanks for the advice!

I'm using a windsurfing sail that I managed to grab on ebay for cheap. I want to be able to determine the best shape for generating lift but reducing the drag force. what kind of calculations should I be using to work it out? Is there a general shape that definitely makes it faster?

Going to be bringing it down from 4.75m mast and 2.2m boom to about 3.5 and 1.8. Any mathematicians got any suggestions on the best shape to recut? or equations i can use?

Perfect!

Is it plausible to cut it from the other side? Not sure how far my sewing skills will take me if I have to take off the sleeve

I just mark out and cut the rear/leech off the sail. (this is what we do with cammed sails, as it's very complicated adjusting the mast pocket/luff with retained camms.)

Resew the trailing edge reinforcement back to your sail.
Unpick the last 150mm of the batten pocket off the "off cut" and slip them back (in the right order so the batten can pass through it)under the batten pocket that remains on your sail. You can just heat seal the Dacron cut with a cigarette lighter, or fold 15mm back under before you stitch it if your fussy) This ensures that all the batten tensioning system is retained and then carefully trim your battens to their new length.

Reuse the outhaul clew eyelet at the back as well.

If possible use "landyacht's" ideas and make the bottom/foot of your sail curved. A 50mm dish downwards in the middle, traps the sail onto your boom in light winds but it can still change sides when the wind increases. Works a treat!!!!
Make sure you allow enough clearance for some mast bend when fully sheeted in for the boom to clear your head.

Very easy to unpick these sails, just lay them along a table, clamp them really tight to each end of a table and gently lift the materials apart and nick just the stitching with a snapblade knife. (once you get started it's easy. You can completely strip a sail like yours in 1/2 an hour.

You may just be able to remove some length off the bottom of the whole sail (Luff/ mast pocket as well) to make it shorter in height.

Well it certainly isnt perfect, but it's ready to be sewn. what do you think?

gday fling cab, we have been slow havent we.No idea who to contact in hobart, maybe go back to the beach and talk to the people who wre on the beach
