I would opt for a gaff catboat rig for easy handling, dousing, and stowing. You want a short mast, long boom, and rather short gaff. Use aluminum tubing stuffed in sleeves sewed in the front, bottom, and top of the sail. Step the mast on the bottom of the boat, passing thru a thwart near the stem. No standing rigging. Dropping the peak halyard (that supports the aft end of the gaff) reduces sail area quickly and substantially, but leaves you with enough to maintain a heading and move the boat, albeit not too close to windward. Make test sails out of any old thing until you feel you have it right. You will have a ball, I guarantee.
