I've got my C-Dory at the bimini shop right now having a bimini fabricated for it.
During the design process, the shop let me choose the thickness and strength and placement of the support frame and struts.
We looked at several alternatives, including building a frame at the back of the pilothouse, which would support almost anything on the bimini top, as well as provide extra handholds when getting in and out of the boat.
We settled for a design without the pilothouse frame, but went with one where the rear bimini supports double as grab handles when using the boarding ladder on the back to get into the boat.
My experience has been a good bimini shop can pretty much design anything you want.
And they can assemble a paper and cardboard mockup and put it in the boat so you can see how it looks before they start drilling holes and cutting fabric.
Using the mockup, we saw areas where supports would cause problems filling the fuel tanks, so we adjusted those and tested all the hatches and ingress / egress areas just to make sure all worked the way we expected.
It's nice to see the mockup and know what you are getting before things progress to far.
