On my Sharki 127 I have the usual stainless tubing support for the strut for the spinnaker pole. The support has a clamp assembly (6 fasteners) on the cap shroud and hides a 120mm length of wire.  The spport crimps onto the lowers with just one fastener.
I am curious if an owner has experienced a corrosion problem on the cap shroud where it it hidden within the support clamp assembly.  This is a place to collect dirt and must be disassembled for inspection.
