Well, I joined the ranks of Roger (flrockytop on C-Lover) and Robert (BRAZO) and ordered a canvas frame from Blue Coral. I made a few additions to theirs and am very pleased with the results. Installing it was a bit tricky, but in the end it turned out great!
Like Roger, I can hang from the "monkey bars" (as my wife calls them) no problem (and I weigh more than he does). We added the side rails to the frame for the Thule rack so we can carry bicycles, kayaks, or a roof storage box as needed. We haven't tried that yet, but will in the next week or two. I also had tabs installed for deck lights, speakers, flag staff, and anchor light.
Thank you to Roger (C-Lover) and Robert (BRAZO) for all their help with this project, and to Rowland Stanton at Blue Coral for great service.
The cost of the frame with side rails, rocket launchers and canvas; packed, crated, and delivered to my door by motor freight, was about $2350 (freight from FL to northern NY was less than $150).
I think we will find it far more useful than a conventional bimini top.
