That's Emmard from PEI - quite the character.
A dodger is built a piece at a time, then sewn together. But the first step is to get the frame right - you've got to be happy with the heights, the angles, and the curvature. My mistake is that I should have increased the curvature in the bows - I still get some pooling in the top center.
I started with the center section - with the zip open window. Then I worked around each side, one panel at a time. Sections of clear vinyl separated by sunbrella in way of the frame tubes. Each panel gets sewn to the previous piece, then the snaps installed and taped to the top frame to keep them taut. For the aft sections, I added a snap to the frame so the panels would curve properly. Finally, the top gets fitted to fit and the zipper added to secure it to the aft bow.
One big change I added to the frame was to make it self-supporting. Struts to the deck hold the fwd frame, then additional struts support the aft frame. The dodger no longer relies on the dodger to hold it in place.
Oh yeah, if your frame isn't at least 1" stainless, you need a new frame. 7/8" stainless is fine for the supporting struts.
