The Dutchman works with conventional or full batten sails and can be easily retrofitted to an existing main. There is no effect on sail shape.
The Dutchman Sail Flaking System uses vertical control lines laced through fairleads in the sail. The lines are attached to the topping lift and at the base of the sail and don't move. The sail slides up and down on the lines like a roman shade. As you drop the sail, the lines guide the main down to alternate sides of the boom. A few seconds straitening and you're done.
