mine, and I'm guessing from what you said, yours, looks just like Mike D's, the straight off the windshield frame, which leaves you without standup headroom - mine has a zippered hatch above the helm, which you can open up, so that you can stand up straight at the helm.
In the Pictures forum, there's a thread on seafari pix, and part way down is a shot of a white seafari with a blue top, re-done with a vertical isinglass segment, then the bimini, so that there is standup headroom underneath - that is the way I'd go / will go when I redo mine.
I saw this one down on Martha's Vineyard this past summer- damn sure looks like a seafari, especially from other views, I circled around it to be sure, even though the name was removed from the side, transom redone to 25", and a big Merc hangin on it...
