Hi Chris,

The hex bolt you see at the port shroud fittings goes through to the starboard shroud fittings; the bolt also goes through the crane that holds the forestay shackle. The nut used on the bolt is a casstelated  one:

All stainless self-locking flex nut. I used stainless washers that come fitted with a neoprene backing to isolate the ss from the aluminum

There is actually a circular top piece of aluminum that closes off the top of the mast. I rabbeted this piece so it could accept a gasket; I drilled and threaded the crane to accept ss machine screws. These are coated with a product called Tuff-Gel that isolates the two metals.

I radiused the piece that is the crane, so I could drill appropriate sized holes through the mast.  Then I cut out the material between the holes which allowed the nice fit of the crane.
