Small addition to what Shrew said.
If canvas snaps to windshield, that is called a Convertible Top (as I was politely corrected by Letas when I ordered one for my boat)
Bimini Tops are the free floating ones that normally have straps that attach teh front and rear of it.
Convertible snap to windshield and then strap to the back only. They can also have additional pieces to enclose the entire cabin such as side windows and rear section with window.
In either case, Letas is the place to go. She can make any Maxum top in Sunbrella (and others) in just about any of the colors offered. She will even sell you the snap tools so you can do the job right.
