Hi Paul, Interesting thought. You should read this article. Lightning does not care whether a mast is grounded or not. It will hit either one with the same statistical frequency. By grounding the mast you provide a path for the strike, once the positive and negative branches connect, to ground without using other conductors on its way to ground through a boat. If the boat isn't grounded, it will likely blow a hole in the hull, or through any other thing in its path, like the crew.
Best regards,
