    Hello,
    I need a detailed document which tells about how to design a complete gaff rig.
    thanks

    Gaff rigs come in hundreds of configurations. Each region has its preferences, which are not necessarily better than the others. Also, rigs have evolved through the centuries. Can you narrow your question?

    What kind of boat and purpose? If you can get either one to read, "HAND,REEF AND STEER" by Tom Cunliffe or "THE GAFF RIG HANDBOOK " by John Leather, or both..;-)

    Not really. They are complicated, heavy and not too efficient compared to a more modern rig. That is the reason they went out of style. For example, you have two halyards instead of one, and there is an extra spar. On a catamaran, with the wide staying possible, a marconi rig doesn't need spreaders and can use a relatively thin mast. Also, if you are on a tight budget, marconi used sails are available for not too much money.

    those are the pictures the catamaran that I designed and builded

    I made this catamaran. Just 160 kg. 6 meter long and 3 meters wide...
    The problem is buying a professional material for rig and sails are too expensive here. I am looking for a better solution to the rig and also the trampolin system.
    Thanks

    Cat rig is simpler. Regardless, take a look at the Wharram Tiki design and pictures across the internet which were built with bermudan and gaff rig.

    nice looking cat did you take pictures of it as you were building it, or do you have build thread here? I would like to see more of it.

    Thanks OPD

    If you want cheap and simple, a lug or sprit rig would be a good choice.

    Concur with Gonzo. For the boat you have a dipping lug, a sprit or maybe gunther rig would be fine.

    Hello,
    I designed and build this myself. Those photos are all just of it.

    J. Wharram did some high aspect gaff rigs on his cats. If you want something appropriate for a catamaran it's a good place to start.
