Interesting question. The term ‘ground’ probably should be distinguished from
the negative side of the dc circuit.
Can’t speak to more sophisticated boats but in my relatively simple 33-2 The
AC system is isolated, grounded only when connected to shore power. I do not

You do run a wire to the engine, usually 2 gauge, but only one. Many
boats ends up using the engine block as a ground bus with wires hooked

Dave — tie the shield to the negative power wire at the power supply lead to
the plotter. I’m sure there’s no RF grounding system on most of our boats; you
start seeing it on larger vessels or those with SSB installations.

Hi- I am installing a new Raymarine e95 chart plotter and am confused by the
instructions with respect to grounding. The cable includes both a Negative
(black) wire and a black Ground (drain) wire. Here is what the install manual
says:

Last week a soft ball player in Nova Scotia was hit and survived. As she
reached out to open the door on a storage shed, the shed was struck by
lightning. The current went up her arm and out her foot,
I've heard of using copper pipe (1/2 or 3/4) and a conduit bender. Shape
the pipe to go as straight as possible between a keel bolt and the mast.
Then flatten the ends and drill a hole to accept a large bolt. You can
drill and tap the very top of one of the keel bolts to accept a short

This is not exactly the case.
Keep in mind that a lighting generates a current in thousands of A. That high
current generates magnetic field around it. In turn this magnetic field
generates current in any conductor

I’ve heard in the past of this being done, but using chain. Does anyone know
of instances where this actually works and prevents lightening bolt from
entering the cabin?
