I just had a 27' sailboat survey for insurance purposes and ran into

Number 1. The propane tank along with its associated plumbing and
solenoid valve sit in the anchor locker forward. This locker is vented
at the bottom thru the hull above the water line which also acts as the
water drain.
Sounds like a kludge, but it may be more space-efficient to only build
one water/vapor tight compartment and use it for both.

... The running light wiring runs to a terminal strip at the
top of the locker. The surveyor says this is a no no, that no electrical
wiring can be in this locker! In that case, how can they justify the
solenoid being in there?
Because the solenoid is (or darn well better be) a non-sparking type.
It is inside the compartment so that it can shut off propane *before*
it gets outside that compartment and into the rest of the boat.

If the solenoid doesn't say 'spark free' or 'marine rated' or
something like that, replace that too even if the surveyor didn't
recommend it.

As for the contact strip- that's shouldn't be used in running light
wiring... shouldn't be installed in a place guaranteed to get wet if
not immersed... and could make a spark if contacted while live. It
should be easy to replace the running light wires, without a contact
strip in line.

As for "no wires in the propane locker" I don't think the ABYC
recommendation is that strict. It's a good idea to not have any wires
not specifically needed, like the solenoid wiring. But if there is
absolutely no possible conceivable way to run the wires to the running
lights without going thru the anchor/propane locker, then call the
ABYC and ask for an interpretation of their standard.

Second problem. This boat was converted from a diesel inboard to a
Honda outboard. The diesel tank was fitted and vented for gas usage.
That was a bad idea too, for several reasons.

There is no bilge to speak of in this boat, but the surveyor says the
boat needs a bilge blower because of the gas tank!
And he's right.
Some alternatives: replace the diesel... use an external gas tank,
kept in the cockpit or aft deck or some place NOT inside the hull;
that way you can use the former diesel fuel tank for something else.

Gordon don't take this wrong, but I hope you didn't pay a lot for this
boat. It sounds like it was owned & maintained by one of those
"independent thinkers" who are often a danger to themselves.

Thanks Roger.... oh wait, you meant the surveyor

The solonoid is probably designed to operated in an explosive environment.
All that terminal strip needs is contact with a metalic object, like a tin
foil hat, to make your boat a big fat statistic.

What do you think of running wires.... properly mounted & protected of
course... thru the propane locker?

.... You can have this stuff fixed before the insurance company
even replies. What kind of risk do you think it's going to make them think
you are if you bother them trying to argue against a surveyor's
recommendations? I wouldn't be surprised if they just canceled you instead
of wasting their time.

Excellent point.

Besides, it will be a lot more profitable in the long run to continue
going over the boat with a fine-toothed comb to find all the little
problems that the surveyor missed! And this isn't intended as an
insult, it is impossible to catch every single thing on even a small
boat.

Update on the survey
Wires in the propane locker were butt spliced and sealed with silicone.

Blower in the gas tank compartment
Not necessary because, as this is an outboard engine, the ignition
source is gone. And to add a blower would be adding an ignition source!
Gordon

Incorrect. The exemption for an outboard would be for a portable tank that is
not in a confined space. You have a permanently installed tank. The blower would
NOT add an ignition source, and the blower would be designed and built
specifically for safe operation in an explosive atmosphere.

I would agree in theory, but I couldn't find anything in my (old) ABYC
standards that said that unequivocally - it seems to depend on the
location and ventilation of the tank. In fact, I don't think the
outboard powered version of my boat has blowers, although in that case
there is no bilge under the fuel tank.
