To each his own - that's why they make all different kinds of canvas. Personally, though, if the boat had a good windshield I would never own a Bimini.
The problem today is that the windshields are all too low, making a convertible top impractical. Even if they are high enough the curved glass makes the view distorted. I don't like standing up, but many boats today require it.
I have been looking at new boats and have yet to find one that suits me. Most have the top of the windshield below my line of sight, or right in front of my eyes. Can't drive without good vision. Also, most Biminis are so high that a lot of shade is lost.
My current convertible top will easily shade 4 people. Plus, it keeps mother warm for 3 seasons. Sure, you can put a plastic "window" between the top and the windshield, but the distortion there is greater than the foolish curved windshield.
I guess i'll just have to keep the old girl another year (the boat that is).
