Some of the companies that make dodgers have patterns for different boats. But the best way to get want you want is to find a local company that can measure design and build a custom dodger. My wife made one for our Ranger 29 and it was a daunting task. Issues come up as to whether you will helm the boat looking above it or thru it. Big difference. If you want to look over it will you have headroom to go below. Windows - you need them. Do you want them to open? Removable panels? Will the side of the dodger interfere with the winch handle circumference? Can you get out of the cockpit without undue interference to the side deck, or off the boat? Handholds (I strongly recommend them)? Will the dodger fold down easily? Fit forward of the companionway? A great dodger is a huge improvement to life aboard. And it is a work of art. If you can get a pro to build you one.
