You have any pictures, because I don’t think I understand what a ‘convertible top’ is. Aft of where it’s snapped to the windshield, how does it attach? Is it entirely canvas, or does it have clear “windows” ?
I have three covers for my boat, Trailer cover, which obviously I can trailer with at any speed. Attached to the trailer frame with probably 10 straps, and a draw string around the base.
Mooring cover, which I trailer with any any speed. Attached to the windshield, and tight to the gunwales and across the transom with snaps, Something like this..

And of course a Bimini top, which I trailer with just to get around parking lots and such

I used to also have what I called a camper top, which essentially was a combination of a mooring cover, snapped all the way around, but extended up to the height of a Bimini top, with clear eisenglass windows all around, aluminum tube frames with a few straps holding them in place. No trailering with this one. I am guessing this is what you have?
If so, might be time to start shopping for a trailer cover; those are generally pretty cheap compared to the custom fit options. Well, boat cheap at least.
