Re: Stus-List Keel bolts comment/question

[Rob Ball via CnC-List]

I have watched a number of keels removed from a hull.  Most all the time the 
epoxy held the keel when the nuts were removed.  In fact there are special 
wedges made to try to break it loose  . . . . . It is a really tough job  . . . 
.
Bottom line, in my opinion, it will not matter whether the torquing is done in 
or out of the water . . . .

This was my experience when removing my keel. We had to “break it loose” when 
lifting the hull.

Question for you Rob, my keel joint had epoxy for the keel stub/keel joint 
which I assumed was done by a PO when the bottom was peeled and epoxy coated. 
Was it actually done at the plant?

Stus-List Fresh water flush...

[David via CnC-List]

Adding a third water tank.   Thought I would plumb in fresh water flush with 
backflow protection from third tank to conventional head.  Anybody try that?

I'm doing this now to my 30 MKI. I plan to isolate the tank in the v berth and 
use it for the electric flush.

Re: Stus-List Keel bolts comment/question

[Ken Heaton via CnC-List]

We had our keel off once a few years ago, to check the keel bolts, and to
do some repairs to the the keel sump where there had been some excessive
material removed in an earlier repair.  Our keel weighs 7000 lbs but with
the nuts off, hanging on it own weight on just the bolts it didn't move at
all.  Wedges were needed to break it loose and then a couple of very short
hydraulic jacks slipped into the gap to push the keel the rest of the way
off past the keel bolts.  They tell me there was about 10,000 lbs. of
pressure on the jacks to push the keel bolts and keel down and off.

That thing was not going to fall off on its own.  ...and on examination the
keel bolts were perfect, not the slightest sign of crevice corrosion or any
other issues.

Re: Stus-List Fresh water flush...

[Danny Haughey via CnC-List]

is your water system pressurized?  if so you'd need a vacuum breaker and 
some kind of valve for filling, I've the fresh head on my boat it has a 
vacuum breaker and you open a normally closed valve to add water and 
then pump the evacuate.  So I guess the difference id the pump does not 
bring water in.  If you're still manual and pumping to fill you may just 
have to separate out this tank from the rest of the boat and this will 
be solely for flushing the head.  Fresh water flushing does wonders for 
that dead marine life smell and it is an upgrade well worth doing.  I 
wonder if raritan makes a retrofit kit to become a freeah head

Pressurized yes.  But I was thinking of isolating it with valves for head or 
fresh water pump sourcing as needed (long trips)

Re: Stus-List Keel bolts comment/question

[Rob Ball via CnC-List]

All the C&C Keels have a safety factor of FIVE with the boat heeled 90 degrees  
. . . . so that keel joint is pretty conservative.

Cracks and ‘Smiles’ are normally the fiberglass bending (it is plastic 
remember) outboard of the bolts and washers  . . .

The best thing to do (although we never did it) would be to have the ‘washers’ 
the full width of the sump – to hold that corner down to the keel top.  You 
can’t get all the way, of course, but the farther (closer) to the actual 
outboard corner, the better  . . .

Re: Stus-List Fresh water flush...

[Marek Dziedzic via CnC-List]

An easy solution for avoiding the dead marine life is to plumb the head intake 
to sink drain. In normal operation you pump the water up through the drain into 
the toilet bowl (you may need to close the sink); the last flush before going 
home - you fill the sink with fresh water and use it to flush the head. No 
stink.

As a bonus you can get rid of one through hull (one fewer hole in the boat).
