Thanks for the tips and added details to consider. I do need to get the actual dimensions of the controls, but am figuring there should be plenty of room along that right side rail/gunnel. The wheel is shifted to the left. Also, the picture angle is weird, but the wheel will not overhang the edge into the cuddy access. I am planning on hinges on the left so the passenger can deal with the open door rather than the driver.
I got adjustable height seat pedestals figuring there is no way I will know what height I will want the seats at until actual seat time. The bottom of the wheel will be 25" from the deck. The seats also have 5" of slide travel so standing at the helm can be achieved. Ergonomics are important. I must have tried a dozen different layouts on the mockup before I settled on the one pictured. Line of sight to the gauges and MFD being most important. All the switches and panels; bilge, tabs and 8 contura will be below the wheel. That actually made me think of something else.
The helm will be framed with Coosa, but spans will be 1/4-3/8" of solid glass like sheetrock over studs. I am thinking of making something like C-channel or I-beams out of glass and securing them to the back of the helm glass panels. Components like busses, ACR and battery charger can then be bolted to the protruding structures since there will be access to the back side. I'm not sure I am explaining that clearly, but I picture securely bolted components rather than trying to glue them in place.
