Re: Stus-List Air draft for C 41 (regular production model, 1986)

[james via CnC-List]

Joyce,

The only concern for Air draft would be the Wilkerson Bridge that is 
just above Belhaven, NC. It is a foot lower than the standard ICW 
bridges. That area has no lunar tide, only wind driven tides and that 
far up the Pungo River it rarely changes very much. The bigger concern 
that I see is your water draft. If you have the standard 7.8' draft you 
will have to be very careful in some areas. It can certainly be done, 
but it can be pretty unforgiving at that draft. Active Captain has good 
data on the problem areas. Coinjock is the toughest part, but getting 
out of the channel with that draft will lead to a (soft) grounding. 
Also, There is a big Phosphate plant on the Pamlico River that runs 
barges to Morehead City on a daily basis. The plus to that is that they 
draw 8+ feet so you know that the channel between those places is at 
least that deep. The negative is you may meet up with one of them in a 
narrow section of a ditch (dug out cut). In past years, I regularly 
moved a 7+ foot draft sailboat through that area. My procedure was to 
call them on VHF (just call for PCS Barge) and let them know that I was 
a deep draft boat and that I would move over as far as possible.  I 
never had an incident other than a temporary soft grounding. Also, they 
don't run those barges as often as they used to, so meeting one in a 
narrow area is much less likely. If you would like more info feel free 
to email me.

I made it clear under a 65.5 clearance with about 1  foot  (estimate) of
instruments above the masthead. It appeared there was a decent margin of
clearance. We have the triple spreader rig.

Re: Stus-List Engine compartment bilge pump and blower

[ALAN BERGEN via CnC-List]

The bilge pump and blower might have a common return. Follow the (probably)
black wires from the bilge pump and the blower to see whether you have a
bad ground.

The blower on my boat has an in-line fuse, located close to the blower
switch, if you want to check that out.

Re: Stus-List Air draft for C 41 (regular production model, 1986)

[Dennis C. via CnC-List]

Go to sailboatdata.com and find your boat.  Most listing include a side
view design drawing with the waterline shown.  You can eyeball an
approximation from that.

I'd say Ken is close for many of our models with his 18" distance below
waterline.

I have the drawing framed and on the wall in my home office.  I refer to it
often.  It's a 50:1 scale drawing.  I've always used 18" for my 35-1.

Re: Stus-List Air draft for C 41 (regular production model, 1986)

[Chuck Borge via CnC-List]

Now you’ve got me wondering...
Since the mast step shoe is at cabin sole level on the transverse grid 
structure, it’s well above the keel sump and associated bolts. 
That said, it may still be below the waterline, but not much. 
I think I’ll take some actual measurements once she is out of the water this 
fall.

Re: Stus-List Air draft for C 41 (regular production model, 1986)

[Dennis C. via CnC-List]

I taped a 100 foot tape to the top of a long stick then taped the bottom of
the stick to a halyard, hoisted it so the top of the stick (and tape) was
raised over the masthead and was even with the tallest thing on the mast
(VHF antenna), then put the tape on the water.  This method should yield a
result which is a couple inches longer than the actual draft.

Re: Stus-List Air draft for C 41 (regular production model, 1986)

[Andrew Burton via CnC-List]

Can you go up the mast with a tape measure? If so just hold one end at the 
masthead and have someone else take the other end to the waterline. That will 
give you a slightly high number which should make you feel better.
That said, I would be surprised if you didn’t fit under the bridges.
This should help you, too https://sailboatdata.com/sailboat/cc-41

Really struggling to get exact measurement of our mast above waterline on
C 41 1986 (just the normal design model) to see if we could do the

 Anyone know how I can get a more exact measure - did the halyard thing,

Re: Stus-List Interesting electrical problem

[Dreuge via CnC-List]

Hi,

I agree, this sounds like a large voltage spike.  As noted, a direct lightning 
strike (and even an EMP from close strike) can wreak havoc on electronic 
without either being turned on or blowing the fuse.   Since, there was no 
mention of weather, I agree with those suggesting an alternator spike.  

It is possible to be an intermittent fault within the alternator, but given the 
marine environment, it’s more likely a connection problem, either positive or 
negative.   Don’t over look a bad negative connection.   An alternator can have 
a good ground connection but have a bad negative terminal connection.  This is 
why companies like Balmar recommend a dedicated negative cable, same size as 
the positive cable, connecting the alternator to the negative terminal.   

That said, I knew of a person who tried to make things better by installing a 
dedicated negative cable. Things worked well for a long time until he upgraded 
his alternator to a high end brand.   He was really pissed when he found out 
that his new system would only charge his house battery and not his start 
battery.  He originally had a working system, and the thought was that the new 
alternator somehow messed with his battery isolator by damaging it or just 
keeping it from working.  The problem turned out to be a bad connection between 
the negative terminals of the house and start batteries (maybe they got 
disconnected and forgotten).  The new alternator had an isolated ground whereas 
the old one did not.  The old alternator system worked because the two 
batteries' negative terminals were connected through the dedicated negative 
cable to alternator to engine to start battery negative.  With the new isolated 
alternator, the alternator negative was only connected to the house negative 
terminal.

Re: Stus-List Interesting electrical problem

[Don Kern via CnC-List]

Last year the voltage regulator on the alternator died, apparently  
causing a voltage spike. Fried two new batteries and my instrument 
cluster, radio survived.  My usual practice was to charge both batteries 
at the same time when engine is running. When under sail run the 
electronics off one battery, odd (Batt 1) or even (Batt 2) depending on 
the date. Now charge only one battery at a time, depending on which I 
was using for house/electronics. Still powered by an Atomic 4.

Hi,

I'd check the battery and alternator connections carefully. And the 
main switches, too. If the batteries get disconnected while the motor 
is on, the alternator will create a load dump that can be even over 
100V for a fraction of a second. In principle, automotive and marine 
electronics should be protected from that but you never know. I'm only 
speculating, but if that was the reason, maybe the voltage spike was 
short enough that the fuses didn't have time to heat up?


Google for "load dump" if you want to learn more.

Re: Stus-List Interesting electrical problem

[Dennis C. via CnC-List]

Ian,

I'm perplexed.  Can't offer any solution, just a story.  I was driving my
1993 Nissan Pathfinder on the Interstate when the entire truck shut down
and the cabin filled with smoke.  I mean the entire electrical system
died.  No electrical of any kind.

Managed to get to the side of the road and have it towed to a garage.  Had
to replace a whole bunch of electrical components to the tune of $6000.

The garage said the alternator caused a voltage spike.  I filed with my
insurance company and they paid all but deductible and the cost of the new
alternator.

I lost chart plotter, knot meter, vhf radio and music radio a few years
back due to lightning strike. Boat was on the mooring with no switches on.
I opened the vhf days later and could smell burnt plastic. Also my masthead
vhf antenna got cooked.

Re: Stus-List Interesting electrical problem

[Matti Airas via CnC-List]

Hi,

I'd check the battery and alternator connections carefully. And the main
switches, too. If the batteries get disconnected while the motor is on, the
alternator will create a load dump that can be even over 100V for a
fraction of a second. In principle, automotive and marine electronics
should be protected from that but you never know. I'm only speculating, but
if that was the reason, maybe the voltage spike was short enough that the
fuses didn't have time to heat up?

Google for "load dump" if you want to learn more.

Cheers,
