TM==>(A poor Conductor is analogous to placing a Resistor between the

TM==>MUCH more efficient Ground for the Mast.
TM==>SYRINX has a mast some 50+ feet above the Waterline, and i have had
TM==>hits as near as 15-20' off the aft quarter more than once. And probably
TM==>Dozen hits within 100' over our 8+ years of cruising. We have NEVER been
TM==>hit, although boats 100' away crossing the gulf Stream with us were,
TM==>losing all Electronics and Lighting..
TM==>The successful plan on SYRINX (with it's plethora of Electronics,
TM==>Gear, Computers, and Antenas ALL over the place!!<G>), has been to take
TM==>a Wide piece of heavy Flexible Braid and Clamp it to the (uninsulated)
TM==>Backstay with a Large Electrical-U-Clamp - It is sufficiently long to
TM==>stay in the Water even in violent tossing, and is weighted pretty
TM==>adequately by it's own mass. (Although a piece of Lead shoved up inside
TM==>the Braid and soldered/Clamped in place wouldn't hurt, I suspect) Except
TM==>for Anchoring or Storing in the water for extended periods of time, this
TM==>Braid is NOT left in the Water between Storms, as it IS susceptible to
TM==>Corrosion if left submerged a long time..
TM==>In addition, I have a #2 Copper cable running from the Mast Tabernacle
TM==>Bolts directly down to a fairly large (around 2" x 10") Copper-Alloy
TM==>Porous Grounding Block on the Hull..
TM==>Lightning can be VERY dangerous, as well as fatal, of course.
TM==>There IS a theoretical 60-degree "Cone of Protection" ( /|\ ) beneath a
TM==>well-grounded Mast or pole, but Lightning often forgets to follow the
TM==>Rules!! (as we have all seen!! <G>)
TM==>She has been floating in a Marina now here in Merritt Island FL
TM==>over 7 years now, with other boats having been struck around us, and
TM==>still remains unscathed! (Hmmm.. Maybe it's that St. Christopher Medal
TM==>on the Mast Step??? <G>)
TM==> And, Sorrowfully, because of Heart and Polio
TM==>problems, she is going to be for sale soon.. :-(. . .

Write your reply.

assistant: Hello Tom!
Thanks for your light, informative and spirited reply!
Mast
Remind me never to sail near you in a thunderstorm! ;-)
Ham
Where I sail, there is no salt.
Respect it!
Hey Tom, I take potential death very seriously, right up there with
taxes!
At least it's nice to have the "rules" on one's side <G>
for
There's that pattern again <g> the boats around you get hit, you
don't!  If I'm ever sailing in Fla. I don't want to anchor near you
:-)
Aww Tom.  I'm really sorry to hear that!  Now for heart, there are
lots of gradual exercise programs that can strengthen and bring it up
to par, aren't there?
Polio, suppose that's more formidable.
Maybe there will be a "virtual sailor's" program for computers, that
will compensate in a minor way.
Best wishes.
