Bonding Mast For Lightning Strike

[silverp40]

I have our mast already bonded to a 3/4" thru hull with 2/0 cable . It is connected through a stainless tang (not a great conductor) via the mast step.

I am thinking of tapping the mast and connecting with another cable via a screw to another thru hull.

Will a connection to 2 through hulls bonded to each other and all the rest of the thru hulls and stays be more effective as a lightning conductor than just a smaller one by itself? Also, can a big strike blow a thru hull out the bottom off the boat (and sink it)?

Thanks for any comments or ideas...

Lightning always follows a path that it determines, which is always unpredictable because of the variables involved.

For centuries experts, amateurs, and idiots have attempted to control lightning. None have really been successful...if they had, we would all know the one answer to your question...think about it.

We have never been struck, but have been close to a boat that was struck. He had a carbon mast. The electromagnetic pulse did more damage than the electric charge and there was no visible exit-path to the water. His mast was not bonded. The boat was a 43 Katana.

There are hundreds of experts here that will fact-check (google) every answer to your question.

Good luck.
