OK, hypothetical, but my quesiton is how do you handle being caught in
a lightening storm in a boat.

I have two fiberglass boats an 18' and a 23'.

18 has an enclosed bow, and the 23 a small cuddie. basicly a bigger
enclosed bow.

Where I boat is Lake Carlyle, and it's about 10 mi. long and about 3
mi. wide. Now 'pop-up' showers arn't uncommon this time of year, but
sometimes that little sprinkle can turn into a lightening storm while
the boater is unawares. So while being caught in the rain. the bilge
[s] are on, and you're headed in. the baot is wet.. you're wet. what
is the concern about lightening?

I'm thinking at least sit still and everybody head under the
enclosures. until at least the lightning quits.

What say ye?

Lightning is incredibly powerful and unpredictable. In all honesty
there is *no* safe place on a small boat. The only obvious advice is
to try and avoid the storm and get off the water, additionally, stay
away from metal objects or any other electrical conductor.

I've taken one really near miss in a 50 ft sailboat as well as being
in an airplane that took a direct hit. Both times it felt like the
world was coming to an end.

My house took a hit on a lightning rod six feet from where I was
sitting. Not all that loud. Lightning bolts vary in power.

Not much you can do about it other than try to stay at the lowest
point in the boat, duck and cover.

I supposed you could install a grounding system on the cuddy, but a
really effective ground system would include straight wire runs and a
through hull ground plate. There really isn't much you can do.

The NFPA and NASD recommend the following:

Stay in the center of the cabin if the boat is so designed. If no
enclosure (cabin) is available, stay low in the boat. Don't be a
"stand-up human" lightning mast!

Keep arms and legs in the boat. Do not dangle them in the water.
Discontinue fishing, water skiing, scuba diving, swimming or other
water activities when there is lightning or even when weather
conditions look threatening. The first lightning strike can be a mile
or more in front of an approaching thunderstorm cloud.

Disconnect and do not use or touch the major electronic equipment,
including the radio, throughout the duration of the storm.

Lower, remove or tie down the radio antenna and other protruding
devices if they are not part of the lightning protection system.

To the degree possible, avoid making contact with any portion of the
boat connected to the lightning protection system. Never be in contact
with two components connected to the system at the same time. Example:
The gear levers and spotlight handle are both connected to the system.
Should you have a hand on both when lightning strikes, the possibility
of electrical current passing through your body from hand to hand is
great. The path of the electrical current would be directly through
your heart--a very deadly path!

It would be desirable to have individuals aboard who are competent in
cardiopulmonary resuscitation (CPR) and first aid. Many individuals
struck by lightning or exposed to excessive electrical current can be
saved with prompt and proper artificial respiration and/or CPR. There
is no danger in touching persons after they have been struck by
lightning.

If a boat has been, or is suspected of having been, struck by
lightning, check out the electrical system and the compasses to insure
that no damage has occurred.

Having had radio towers, I can tell you pretty much flat out that
there's not much you can do about lightning strikes - I went for years
without getting a direct hit on the towers, then in one year, I was
hit six/seven times and at least twice, three times a year up until
the time I took them down. You can protect your equipment using gas
discharge devices and direct, heavy ground straps, but other than
that, forgitaboutit.

I have an aluminum cuddy. Better than a glass bow rider, at least.

Bull****. Apparently, you have never seen (or had to repair) an
aluminum aircraft hit by lightning....

I was in one that got hit by lightning - a stretched DC-8.

The static discharge sticks on the wings were glowing with green
plasma for about two minutes after the strike. :)

I have pictures that I show students..... huge fricking holes in the
side of the A/C..... minor compared to the ecological disaster
perpetrated on the FO's seat.................

ROTFL!!!

I'll tell you, it's interesting when it happens. The guy sitting next
to me on the way back was a chopper pilot and when it happened, he
thought it wasn't a direct hit - he thought we got passed by and were
in the plasma cone rather than the direct path on a cloud-to-cloud
strike.

The reason he thought so was there weren't any holes anywhere on the
wings or cabin. :)

When I had my towers, I went through a whole bunch of gas discharge
connectors one summer and finally had New England Tower come over
and completely redo the ground system - buried a lot of #10 copper
wire in a grid, staked with 8 foot ground rods and each leg of each
tower was hard bonded to the grid. That helped a lot - the number of
strikes the following year went down significantly.

Don't ask me why.

I believe there's a theory that a good grounding system will bleed off
accumulated charge before the voltage gets high enough to initiate a
leader stroke.

Pretty much what everybody else said.
I once posted a link
Still have it
http://edis.ifas.ufl.edu/pdffiles/SG/SG07100.pdf
Mostly about sailboats, if I recall, but there should be an
interesting part there about a "cone of protection."
Not to be confused with the Cone of Silence.
Here's something else you don't want to hear.
Lightening strikes in fresh water are MUCH more intense
than those on salt.
Don't know or can't remember why. Ain't a scientist.
Staying away from that stuff is the best bet.

I put on the life vests, put my antenna down with the radio off, say a
few prayers, wish I didn't have to pee so bad, and head for home - at
a slow pace 'cause I can't see over the waves.
