Chris, I'll try out the bimini. If it doesn't work...
I measured and I think it will fit if I mount it in line with the steering wheel, which is closer to the companionway on the E39. I'll have to dry-fit it to make sure.
Ted, if I buy it from Chris and it doesn't work for my E39, would you still want it? I'm in Severna Park, a lot closer than St. Leonard.
