Hello @Stevep, @SamuelNorris & @Rick-DC,
Here is a selection of some of our preferred reading resource on lightning/surge protection, including for the marine industry from Australia.
- Earthing Calculator - Lightning Protection Services | LPI
- The Basics Of Power Surge Protection - Surge Protection Devices
- http://www.lightningman.com.au/lightning_safety_procedures.html
- How to protect your boat and passengers from lightning strikes | Club Marine Australia
- Lightning Protection Systems - CBG Systems
- https://www.eit.edu.au/cms/resources/books/lightning-surge-protection-and-earthing-of-electrical-electronic-systems-in-industrial-networks
You can also search in your favourite search engine for “marine lightning protection”.
Boats make a terrific conduit for lightening, so putting protection into the equipment is essential. With a metal haul boat, you can earth to the haul. For fibreglass, you will need to get a suitable brass plate on the outside of the boat fitted as far as possible below the waterline that you can earth to.
Happy to Help,
Marcus
