I will tell you from experience that both sides of the pilothouse are
not identical.
These boats are hand laid fiberglass and while they look the same side-to-side to the naked eye, they are not.
I took careful measurements to place the starboard wishbone exactly where I wanted it, then transferred those measurements to the port side.
As a result, when standing in the cockpit and looking up, they are not perfectly parallel.
Remember, even if you are an eighth of an inch off at the base, that translates to a lot more 19 feet out.
If you do the job, mount the first wishbone and put the rigger pole in it.
Then with a friend (or 2), start one bolt on the opposite side and put the other pole in.
have your friends eyeball everything while you get a second bolt in and before you drill the rest of the holes.
Finally, if you think you are going to be able to fit your wishbones around the Parker graphics without putting a hole through part of it, get that thought out of your head now.
Best to just remove the graphics before you start the job.
Ask me how I know this... :roll:
