You'd probably be best off if you checked out the "Sailmakers Apprentice." It's not as simple as just a standard pattern. You'll need to size it to your mast and boom, allow room for the camber, and pay attention to the stress areas...

Just do a Google search for sailing clubs in whatever area you think best....they will probably have a contact link or phone number. Or you could just try the RYA\n(Royal Yacht Association)\nhttp://www.rya.org.uk/

You can find tubes at marine or boat stores near the coast. Also large sports stores usually have them. West Marine, Boaters World, Sports Authority are all a good place to look. Also you can check online.

It depends on what you mean.  If you want to make one from scratch, start with boat plans.  You can get plans from the local library, boating magazines, and even shipyards.\n\nThere are many models available that are in kit form.  You can build those and paint in your own color scheme.\n\nLastly, there are ready to float boats that are R/C.  You can have an out-of-the-box boat in the water in less than 10 minutes, once the batteries are charged.\n\nGas powered boats are the most fun, but they travel too fast for the backyard pool.  You will need a calm lake...or a flooded back 40, to have any fun.  I have a Prather Lap Cat...see link.

It's been forever since I've done it, so I can't give you an actual schematic (try a search engine for that.) I will give you some tips from my science olympiad glory days, however. I assume you're trying to lift the most weight?\n\nMake your sails out of the lightest material possible and with as little re-enforcement as you can get away with it. That way the energy going into turning the sails is minimized and they can rotate faster (and hence do more work.) Depending on size, posterboard or even paper with a balsawood backing usually works well.\n\nDo you know what will be turning the windmill? If it's a fan, try to find one like it and test against that. If you're using natural windpower, this will be harder to do. Only re-enforce the sails enough so they won't get torn apart.\n\nAs far as the string lifting the weights goes, friction is GOOD. You don't want it slipping and costing you energy and time, if time is an element. In all the other elements, friction is BAD. Break out the ssandpaper if necessary.\n\nAll of this is probably common sense, but I hope I did some good. Best of luck.

yes you can, my friend makes them at home, I do not know where you get the diagrams though.
