Lightning Protection

You really don''t want to use the shrouds as part of the grounding system.

Stainless conducts electricity, but not as well as an aluminum mast. In the event of a strike you likely suffer shroud or fitting damage due to internal heating.

On a normal protection system, the mast forms the primary grounding point to either the keel or a submerged plate. The shrouds are only tied in to lessen side flashes and crew injury.
