Hi Brett
If you click on forums/all/ sailmaking in the landyacht section you should find all you need but yes you will need to cut the luff[leading edge] straighter
That sail is quite big so will take quite a bit of modifying I think to suit a mini
Some windsurfer sails lend themselves to converting to landyacht sails easier than others
Because that sail is so long on the foot the luff will need to be brought right back to where it will go through the monofilm window Are you able to sew that stuff?
Otherwise you will have to modify both the luff and the leach so that the window finishes up in the centre of the sail which is quite a lot of work IMHO
Your mast will bend when it is on the yacht and sheeted in
It may be easier to look for a sail that is simpler to modify they can be picked up
for a few dollars on the second hand market some people have managed to find them in skips!
Good luck
HIKO

Oops I stand corrected !
I assumed that the tube was going to be the boom and the clear window was going to be difficult to get around due to its position in such a wide sail compared with the one above
Was both the luff and the leach cut back on Lachlans sail ?
Sorry Brett
Cheers Hiko

No just the luff,and the top of the head on the leach. recutting the leach is lots of work, and thats the only flat part on those old windsurfer sails
on those old sails I just treat the window like it is sailcloth .its usually the last bit of the sail to die.you need to avoid sails that have gone sticky or the mylar is starting to peel. you can still recut , but you will get a rather limited life from it. I save the bad sails up for the mast pockets, batten pockets/tensioners and wear tape. then use the extra scrounged bits when I get a good sail, or as parts on a bulkybag sail.
Recycle, recycle,recycle

Heres one where the lower third is all window material

is it possible for our dear administrator to move the thread to the sailmaking section so it doesnt get lost

.... also forgot to ask too, what would be the recommended rope size and pulleys for these? I have had a look around, not sure what I am exactly looking for....
Is there a good online site to order pulleys from?

Brett

There is quite a lot of load on your sheet rope Brett at times so you want it at least 12mm so its comfortable in your hands also I would suggest you compare ropes in the shop for suppleness they vary a lot
You want the soft and bendy variety as it runs through the blocks easier and there are times you want to spill wind in a hurry
I would like bearing blocks like Landyacht has but the ones I have will have to do for a while yet They do have more friction
Bigger diameter is better with blocks also but more expensive unfortunately
Have a look at landyachts thread on sheeting arrangements in the forum
The split sheet version where you have smaller blocks and rope at the mast downhaul end looks good to me if you are starting from scratch
That would reduce friction also I think
cheers Hiko

mmmmmmmm although my yachts over the years have got smaller my hands havent
My blocks are rather large accordingly also we must use what we have !
I suppose if I was a serious racer I would put up with a bit of pain but I am not

Cheers Hiko

Like I said , I did go down to 10mm, learnt my lesson and went back to 12mm.
bunning sell some coloured stuff in 30mx10mm rolls called GRUNT. complete rubbish for any real job...... BUT....... we bought some , had to stretch it to get the casing and core to match , then cut it into 6m lenghts to try out. some of the guys are STILL using thiers after2 years. not bad a $4 for a 30m roll .
It does hurt me to recommend such a cheap product, but those are the facts of history, so nobody can call me "anti Bunnings'

OK getting excited now - boom done. I ended up turning an old shovel handle down and fitting the sections of timber to both ends of my boom. Worked out quite well.
With help from a work buddy i selected a few pulley blocks.
Tonight, i have just finished completing a mock up of the whole setup, sadly the camera is dead so no photos.

Pretty happy with the whole thing. Still have to fix up the join in the chassis, pin the wheels to the axle and tighten up the steering join.
Hoping to get out this weekend, but I doubt it somehow with a lot happening family wise!
Brett
