The sail looks GREAT .... What a FANTASTIC car park to sail on 
Was it easy to make and did you have any problems in the design and construction?
not many for a guy thats never sewed before. really was fun. like working with
paper.
did you sew- or use tape, and if so....what sort of tape?
I just happen to have a full roll of tyvek taking up space in my shed, but there is a pretty good chance it will soon be on the way to kalgoorlie to the end up at the "WIND, WHEELS AND WATER SKUNKWORKS"
(locally known as Landyacht's place)
just used rubber cement to join panels, inch overlap, then sewed two rows zig zag, 3/4 inch apart.
Wow that looks fantastic - great job!! You've just inspired me to finish my home made sail! 
(just embedded it a bit neater in your post Giz. 
)
as they say in Wayne's World " Dude, that is like way cool"
nice effort fellas. any chance of putting some photos and specs onthe landyacht register,so others can be inpired by your efforts .it looked to me to be a LLM with wooden rear axleand short stays to the base of the mast.
I reckon thats one more "enguneerin' degree" I need to award
Tyvek seems hard to find in Adelaide.... rang 6 places and eventually found some rolls 2745mm x 30m @ about $135.
Had to laugh at one company when I asked for "Tyvek Homewrap" ..... Sorry Sir we dont have anyone by that name working here..... could he be from head office?
Edit;
Got a roll .... it feels weird, a bit like smooth waxy newspaper.
found all the info on sea breeze, landyachts info he provided in the sailmaking section. www.seabreeze.com.au/forums/topic.asp?TOPIC_ID=38326 this topic was most helpful. sorta matched curve of mast when i laid it out. back edge of front vertical panel has even 40mm curve, landyacht used 20mm, i think. was looking for more grunt. everything behind that is flat.
Here is a link of "How to make a Tyvek Sail"
www.boat-links.com/Tyvek/index.html
There actually quite a lot on sailmaking using it.
sn showed me some tyvek the other day, .
I reckon it will suffer from localize stretching around the eyelets etc.
i would suggest that if making a sail that much bigger re-inforcing panels being used and wider seams.
a few notes on contact adhesives, based on experience in sailmaking experiments.
the spray on stuff is no good as the join fails in a few days.
the GEL version( no high from sniffing) is useless . it falls apart after a few days.
basically you have to use the original "non easy to use " glue
Nice Job! I think you could be on to something there. Could do with a foot rest with sides to stop feet slipping on to the tarmac. A very good looking prototype sail too. What is the sq area of the sail?
heres a few photos of team tyveks sail test vehicle. adjustability is the theme.
have about 4 hours on the sail, will look at it closely soon to see if there is wear showing. found when making that one side of tyvek fuzzed easier than other, or so it seemed.
sorry, screwed that last post up. don't know how to delete one. overall sail area has not been determined yet. knew height i wanted (13') and length of foot (5'8") rest was just creativity. also paid close attention to depth and position of camber.
