Re: Bristol 32- Deck Stepped Mast - Lighting Protection

I just finished a repair that involved removing two 1 1/2 sea cocks in the head on my Bristol 32 with a deck stepped mast. The valves appeared to be bonded with wire but I noticed that not all the valves on the boat were. When I traced the wire it led from chainplates port and starboard, down to the valves. It looks like an attempt at lightning protection to me. otherwise, why connect the chainplates. I'm in Seattle where thunder storms are not common. They happen of course, but not like other parts of the country or even eastern Washington east of the Cascade mountains.

I disconnected the wire. The way I see it, there are better paths to ground in the marina than my boat if the big metal stick in the sky isn't connected to the water via wire and thru hulls. The wire wouldn't carry the charge very well anyway.
