GMI bimini measurements
Jerry, the one I ordered was, LENGTH 5 feet 3 bow, HEIGHT 30" to 36", WIDTH 73" to 78", Sunbrella Pacific Blue, 2 feet slide track, stainless steel hardware upgrade. Came to $313US plus shipping. If you don't order SS hardware, it comes to $278US, but I'd recommend the SS hardware upgrade, the bows are still double walled aluminum. though you can get all SS, but then the price is $478US.
I posted information about my installation before, but for the life of me I can't find it!
I mounted mine on top of the coaming, using a slide track. I personally, think it looks better on top of the coaming, but that's just a matter of personal preference. Later I intend to replace the slide track with a T-track with Genoa slide cars. I'll attach the bimini to the same track. That way the track will be dual purpose.
The slide track helps a lot during installation, allowing you to fine tune the position. I used duct tape to hold the tracks in position, while I determined where to drill the holes. Mine clears the main sheet and the back stay just right. I had to trim 6 to 7 inches off the height, so the boom wouldn't hit. I trimmed a little at a time, using a tube cutter, until it cleared. I can sail with the bimini up.
I have to squeeze the supports toward each other a little, but it's no problem. You could mount it on the outside of the coaming just as well, in which case you may need to spread the supports apart a little.
Many have installed theirs on the outside of the coaming just above the rub rail, in which case 79" to 84" width may work better.
