Lightning and Sailboats...

We occasionally participate in various boating forums. [See our Some Forums We Read sidebar for links...]

Some of those topics may be relevant here, so once in a while we will repost on our blog for reference.

The following may be one of those cases. To accommodate our non-boating blog readers, sometimes we add some {additional information and links} to the original forum post, below.

Sailboat Lightning Strike Caught On Camera

The post Sailboat Lightning Strike Caught On Camera appeared first on gCaptain.

Terrible day for this sailboat moored off of Kassandra in Northern, Greece. Might want to give a once over of the electronics after a direct hit like that. At least the boat owner is laid over in a beautiful place if she needs repair.

Timing is everything...

A good reminder to keep spare [and all] electronics secured in a Faraday cage...

Can somebody who has knowledge on the subject, comment on my statement.

Hi Bob,

I've been collecting some lightning resources over time, but am certainly not an expert. The answer to your question is complex- and not favorable. But, statistics [and physics...] demonstrate that you are better off in your metal sailboat than we are in our fiberglass one... However- according to insurance claim statistics- we are better off in our monohull than you are in your catamaran... And all of us increase our chances of being struck 5 to 10 fold while at anchor... Are you sensing a pattern here?... [All this gleaned from the references, below...]

Here are a couple of resources that relate to your question: The first is this well written article in Ocean Navigator [by the owner of an aluminum sailboat that was struck...] and the second is Marine Lightning Protection Inc. [the company founded by the professor referenced in the above article...]

As a general reference regarding lightning and [fiberglass?] sailboats, attached is a publication from the University of Florida entitled Lightning and Sailboats.

In case this is helpful, and may none of us ever find out first-hand how well protected from lightning we, our vessels, and electronics are...
