TomP,
Perhaps I misunderstand, but you are meaning that every bushing ( every pin, every everything) is subject to loads from different directions depending on how the boat is moving ?

It would be really great for you to share some of the formulas for figuring this stuff out. I understand moment arm, the basic physics, but I guess thinking about the velocity vectors of a boat in a sea state is much more complex. I have just been doing all this by rule of thumb , and looking at what has worked on previous boats. (an skenes of course)

That said- when building a new extended mount for something like a tricolor light to be above a masthead , I would really love to figure out the loads that the light base might see when the boat slams in to a wave. But wow ! There must be so many varialbles there ?
