I doubt that ANY grounding technique would be able to ensure that the
instantaneous power from a lightning strike as so well illustrated in the video
could be ‘directed’ anywhere other than where it was going to go anyway!
Keep your insurance up to date, get the h... off the boat and let nature
It may have changed but when I did my bilge pumps the off brand pumps had
longer wires so I could make my connections behind a settee and not in the
bilge. Keep it dry.

The narrow and shallow bilges of these C makes wiring a challenge. The
relatively short wires provided with typical bilge pumps doesn't help
either.
If you absolutely cannot get the wires to reach high enough (just below the
floor boards) then solder and adhesive heat shrink is the best option.
I don't have a tach installed, but do have an optical tach, and reflective
tape on the crank pulley and drive shaft (so I could confirm the trans
ratio is 2.5:1). Most of the time I run around 2000 rpm I would guess (keep
forgetting to check), but this last fill including several hours into 35+
No and No.
Both of these will potentially cause stray current leakage into bilge water,
which can eat metal very fast.
Usually I don't solder DC power wires, but my bilge pump wires are soldered and
heat-shrinked to be totally waterproof where they are exposed to water. I would
also move that
I have two questions related to the correct way of doing wiring in a wet area
(bilge) of the boat.
1. In the process of wiring in my new high water alarm, I found it convenient
to split an existing always hot red wire in the bilge area to run both the
bilge alarm and the emergency bilge
That’s good advice on sacrificial anodes Josh. Thanks

Edd,
What would you be using the fish for that you would be trying to help
with? By what metric would you know if they helped? Would you be able to
prove that it was or wasn't helping and determine why or why not?
Most of the above questions *could* be answered if you had a galvanic cell
and
There is no certainty of a good electrical connection from the shrouds to
underwater metal.

The C I race on has one which is connected while at dock – to the shrouds,
which I assume are connected to the grounding system. My C is seldom
connected to shore power and is run for about half an hour a week (out to the
race course and back), so I don’t use one.

The winter before last a tree fell onto our mast stand. Luckily only the
quick-fit base for our masthead tri-light was damaged. Aqua Signal wanted
so much for a replacement base that I decided to just replace the
whole thing with the LED version.
So far the light has performed well. It's much
Sure is. Note that a LOT of zinc makes a bigger battery, so 4 zincs might go
quicker than 2. As long as the fish gets eaten before the shaft zincs it should
be good.

I hang a zinc over the side that connects via alligator clip to the negative battery terminal. I go through two zinc fishes a year. This tells me it must be doing something.-DaveTerrapin FlyerNew Haven

From: Edd Schillay
Last summer my two shaft zincs and one prop zinc were gone in six months. I
hung a zinc fish, connected to my shaft with a slightly modified jumper cable,
during the winter. Three weeks ago I sent a diver down to change the zincs and
he reported that all were good. Conditions change,
It is a hugely wasted effort attached to random parts of the boat. If it is
connected to the boat’s grounding system it will certainly work and save the
underwater zincs. You still need a galvanic isolator, even 50 zincs can only do
so much to solve everyone else’s issues.

Listers,
Every once in a while, I come across a boat with a submerged zinc hanging from
a wire off the stern of a boat. Some people swear by them and others think it’s
a wasted effort.
What does the group think? Is it worthwhile to add (especially when on shore
power) and, if so, where do
This may be old news already, but quite a lightning strike in Boston!
