Great webpage. The professor of EE is also a sailor.
Enter:
Sailboat lightning grounding
into the Google search engine. There's lots of pages so you can do it
right.
NEVER MAKE A NEAT RIGHT ANGLE TURN ON A LIGHTNING GROUND! If you gotta
be "pretty", don't bother with it at all. ALL turns in ALL lightning
grounds MUST be made gradually over a large diameter, not those
"nautical" perfect looking turns the bilge pump wires have. This
reduceds series INDUCTANCE. Series inductance on the very-fast pulse of
a lightning hit is what destroys it....
