That seems simple enough... replace the gas A4 with a diesel  :)

That's one of its big advantages on boats, that 
it's non-volatile. It's good practice to shut 
down the engine at the fuel dock anyway, but 
they're probably asking that more as a general 
policy due to the gasoline boats they fill (or 
in case some gasoline vapors wafted over to your boat).Â


The flash point (vaporization temp) of diesel is 126 F:Â

I am pretty sure vaporized diesel will blow up 
like gasoline vapor.  I know vaporized cooking 
fat will.  Don’t most of the fuel docks ask 
you to shut down the engine and run the fan while fueling?Â


I had never thought of it as an air supply for the engine. Â

Joe, I have a 10 foot Caribe RIB and a 9.8 Tohatsu 4 stroke.  Together with
full  fuel tank in the dinghy that's about 200 pounds and I find it a bit
much for towing behind and it doesn't tow well at all; even with the
outboard fully raised the prop can drag in the water at 6 kts so for
cruising last summer I used  my little 8 foot fiberglass dinghy and oars, a
little more care required in getting on and off the boat without tipping
the dinghy but much easier to tow behind...it does the trick, but I plan to
get a little Suzuki 2.5 hp instead, that will work nice on the little
fiberglass dinghy when cruising and I'll use my Caribe setup for back and
forth to the mooring.

We  have a 10' Achilles with a wood floor 8 hp nissan. With the motor off and 
the dink empty it's very light doesn't slow us down at all.
I keep it short and directly in back of the big boat even if it flips (and it 
hasn't in a long time ) no problem,  just get it to flip back. that's my story

Yes, 
Rick, vaporized diesel will blow up like vaporized

The 
flash point (lowest temperature at which a liquid starts to evaporate) of 
Gasoline is -45 to -50 degrees F (-60 C, I think). The flash point of #2 diesel 
is 126 F (52 C). Biodiesel, BTW, is about 225 F so if you use B10 or B15 in 
your 
boat the flash point of the fuel would be higher.
 
The 
ignition concentration of a fuel vapor is the percent of fuel vs air that will 
support ignition. Too low a concentration or too high a concentration and you 
get no fire. That is why (if you are very lucky and not too bright, you can 
throw a lit match into a bowl of gasoline and nothing happens. For gasoline the 
range is 1.4% to 7.6%.  Diesel is pretty similar at 0.6% to 
7.5%.
 
The 
ignition point (temperature at which it will start burning) of gas and diesel 
are also very similar. Gas is 475 F, and diesel is 494 F.
 
But 
gasoline is much more volatile, and at much lower temperatures. So you are 
likely to find gasoline vapor vs. diesel vapor.  Any fuel leak at above -45 
F will result in gasoline vapor. A diesel leak will just make a  puddle 
unless the temperature is above 126 F. Yes, it would be a smelly puddle, but 
your nose can sense vapor concentrations far below the concentration that would 
support ignition.
 
Since 
the density of the gasoline vapor is about 2.0 (air is by definition 1.0) at 
standard temperature and pressure (70 F and sea level), the combustible vapor 
sinks to the bottom of your bilge. Diesel vapor would do the same thing, except 
a measurable concentration of diesel vapor could not exist at STP. Even high 
pressure diesel forced out of a pinhole leak in one of your injector lines is 
more likely to result in a smelly mist (too high a concentration to support 
ignition) than in a combustible fuel vapor.
 
The 
flash point indicates when a liquid starts to evaporate. But there is another 
specification called the fire point that is probably a better illustration of 
the relative risk from gasoline vs. diesel. The fire point is the temperature 
at 
which a liquid fuel will generate a vapor concentration high enough to support 
a 
flame for 5 seconds – which is enough time to cause significant evaporation of 
the liquid and start a real  fire (as opposed to a momentary flash). Liquid 
gasoline has a fire point of 30 F (-1 C), while liquid diesel is 154 F (68 
C).
 
So 
unless you are boating in some really ridiculous heat, you are unlikely to get 
a 
fire from diesel fuel. Lots of smell – which may make a blower to ventilate the 
engine spaces very desirable – but a fire is not a high probablility 
event.

The geek in me just has to jump in here with some technical information. So 
here goes:

 

Yes, Rick, vaporized diesel will blow up like vaporized gasoline.

 

And Yes, Patrick, diesel does not vaporize easily. And is a lot less likely to 
support a flame than Gasoline as well.

 

The flash point (lowest temperature at which a liquid starts to evaporate) of 
Gasoline is -45 to -50 degrees F (-60 C, I think). The flash point of #2 diesel 
is 126 F (52 C). Biodiesel, BTW, is about 225 F so if you use B10 or B15 in 
your boat the flash point of the fuel would be higher.

 

The ignition concentration of a fuel vapor is the percent of fuel vs air that 
will support ignition. Too low a concentration or too high a concentration and 
you get no fire. That is why (if you are very lucky and not too bright, you can 
throw a lit match into a bowl of gasoline and nothing happens. For gasoline the 
range is 1.4% to 7.6%.  Diesel is pretty similar at 0.6% to 7.5%.

 

The ignition point (temperature at which it will start burning) of gas and 
diesel are also very similar. Gas is 475 F, and diesel is 494 F.

 

But gasoline is much more volatile, and at much lower temperatures. So you are 
likely to find gasoline vapor vs. diesel vapor.  Any fuel leak at above -45 F 
will result in gasoline vapor. A diesel leak will just make a  puddle unless 
the temperature is above 126 F. Yes, it would be a smelly puddle, but your nose 
can sense vapor concentrations far below the concentration that would support 
ignition.

at standard temperature and pressure (70 F and sea level), the combustible 
vapor sinks to the bottom of your bilge. Diesel vapor would do the same thing,

is more likely to result in a smelly mist (too high a concentration to support

The flash point indicates when a liquid starts to evaporate. But there is 
another specification called the fire point that is probably a better 
illustration of the relative risk from gasoline vs. diesel. The fire point is 
the temperature at which a liquid fuel will generate a vapor concentration high 
enough to support a flame for 5 seconds – which is enough time to cause 
significant evaporation of the liquid and start a real  fire (as opposed to a 
momentary flash). Liquid gasoline has a fire point of 30 F (-1 C), while liquid 
diesel is 154 F (68 C).

 

So unless you are boating in some really ridiculous heat, you are unlikely to 
get a fire from diesel fuel. Lots of smell – which may make a blower to 
ventilate the engine spaces very desirable – but a fire is not a high 
probablility event.

Diesel doesn't vaporize easily, unlike gasoline. That's one of its big 
advantages on boats, that it's non-volatile. It's good practice to shut down 
the engine at the fuel dock anyway, but they're probably asking that more as a 
general policy due to the gasoline boats they fill (or in case some gasoline 
vapors wafted over to your boat). 

 

The flash point (vaporization temp) of diesel is 126 F:

I am pretty sure vaporized diesel will blow up like gasoline vapor.  I know 
vaporized cooking fat will.  Don’t most of the fuel docks ask you to shut down 
the engine and run the fan while fueling? 

 

I had never thought of it as an air supply for the engine.

Well, it is a combination. A good example here:
The C 25 has an aft compartment under the tiller, where the gas tank
sits. It is practically on the cockpit, and any fumes just drain out from a
little drain hole.
Now some industrious owners (like a previous owner of "Tabasco") decided to
open up that area and have more space in the cockpit. Which is wonderful,
but now, the fule tank is in a lazarette locker, hence any fumes or fuel
leaks from an expansion, will leak into the bilge.
So I am paranoid, and open up and smell the lazarettes every time. When I
get a chance, I will rebuild a new fuel tank compartment in the aft section
of the cockpit.
So dinghy fuel tanks, propane or what not are very safe as long as there is
room for the accidentally escaped gas to get away from the inside of the
boat.
I once had a bad junction in my propane tank. 10 lbs of propane leaked
within a day out thtough the went hole into the the ocean/air, and nobody
was ever in danger.

It is a bit misleading to say vaporized diesel can explode.  "Atomized"
diesel can explode.  Atomized motor oil can explode too.  The difference
being that a puddle of gasoline is volatile and will vaporize at room
temperature.  Diesel will not and would need to be atomized by pressuring
it through a nozzle.

The geek in me just has to jump in here with some technical information. So 
here goes:

 

Yes, Rick, vaporized diesel will blow up like vaporized gasoline.

 

And Yes, Patrick, diesel does not vaporize easily. And is a lot less likely to 
support a flame than Gasoline as well.

 

The flash point (lowest temperature at which a liquid starts to evaporate) of 
Gasoline is -45 to -50 degrees F (-60 C, I think). The flash point of #2 diesel 
is 126 F (52 C). Biodiesel, BTW, is about 225 F so if you use B10 or B15 in 
your boat the flash point of the fuel would be higher.

 

The ignition concentration of a fuel vapor is the percent of fuel vs air that 
will support ignition. Too low a concentration or too high a concentration and 
you get no fire. That is why (if you are very lucky and not too bright, you can 
throw a lit match into a bowl of gasoline and nothing happens. For gasoline the 
range is 1.4% to 7.6%.  Diesel is pretty similar at 0.6% to 7.5%.

 

The ignition point (temperature at which it will start burning) of gas and 
diesel are also very similar. Gas is 475 F, and diesel is 494 F.

 

But gasoline is much more volatile, and at much lower temperatures. So you are 
likely to find gasoline vapor vs. diesel vapor.  Any fuel leak at above -45 F 
will result in gasoline vapor. A diesel leak will just make a  puddle unless 
the temperature is above 126 F. Yes, it would be a smelly puddle, but your nose 
can sense vapor concentrations far below the concentration that would support 
ignition.

 

Since the density of the gasoline vapor is about 2.0 (air is by definition 1.0) 
at standard temperature and pressure (70 F and sea level), the combustible 
vapor sinks to the bottom of your bilge. Diesel vapor would do the same thing, 
except a measurable concentration of diesel vapor could not exist at STP. Even 
high pressure diesel forced out of a pinhole leak in one of your injector lines 
is more likely to result in a smelly mist (too high a concentration to support 
ignition) than in a combustible fuel vapor.

 

The flash point indicates when a liquid starts to evaporate. But there is 
another specification called the fire point that is probably a better 
illustration of the relative risk from gasoline vs. diesel. The fire point is 
the temperature at which a liquid fuel will generate a vapor concentration high 
enough to support a flame for 5 seconds – which is enough time to cause 
significant evaporation of the liquid and start a real  fire (as opposed to a 
momentary flash). Liquid gasoline has a fire point of 30 F (-1 C), while liquid 
diesel is 154 F (68 C).

 

So unless you are boating in some really ridiculous heat, you are unlikely to 
get a fire from diesel fuel. Lots of smell – which may make a blower to 
ventilate the engine spaces very desirable – but a fire is not a high 
probablility event.

Diesel doesn't vaporize easily, unlike gasoline. That's one of its big 
advantages on boats, that it's non-volatile. It's good practice to shut down 
the engine at the fuel dock anyway, but they're probably asking that more as a 
general policy due to the gasoline boats they fill (or in case some gasoline 
vapors wafted over to your boat).

You’re right, Joe. 

 

That isn’t an example of an explosive vapor ignited by a spark, but rather a 
liquid mist being heated above the 494 F ignition point of the liquid. And 
that’s not a situation that a blower would help avoid.

I have a full cockpit enclosure on s/v Rainy Days.  When motoring with the 
enclosure in place, the engine's intake air must come from within the 
enclosure, reducing the oxygen content in the enclosure.  I have a new blower 
but the intake and exit are presently inside the enclosure.  I have to modify 
my enclosure so that its not this way.   So, if you ever plan on adding a full

I suspect that C decided to just put blowers everywhere and then not have to 
worry about what kind of engine got installed. Also diesel engines can be 
smelly and maybe they thought it was nice to have a way to pull the fumes out. 
I have never ever heard of a diesel leak causing an explosion, but many a boat 
has burned when a fuel leak encountered a red-hot turbo, Prior to turbochargers 
being water cooled this was a cause of numerous fires.
BTW – there is no way a diesel engine can reduce the oxygen in your boat 
without reducing the air pressure in general. If your enclosure is tight enough 
to hold vacuum it is way better than most!

2015-12-28 Thread Patrick Davin via CnC-List 
Interesting. We have a full cockpit enclosure too, but it doesn't cover the
two stern dorades (they're outside the enclosure) which I presume feed
engine air pretty well (they're above where the old blower was).  Our
enclosure also is nowhere near air tight - lots of air comes in / leaves
through the open corners and bottom edges. But diesels could consume a lot
of air so with a really air tight enclosure also enclosing the dorades I
could see the need for a blower.

Re: Stus-List Proper Blower Installation - 30 mki

2015-12-24 Thread Gary Nylander via CnC-List 
I just went down to Penniless and looked at the blower system – it is about 70 
degrees here on the Eastern Shore of Maryland – Merry Christmas…..

 

We have 3 inch flex hose from the dorades to the engine area. One has a blower 
in-line – it is a metal unit (surprisingly not rusted after 35 years) which has 
the input hose coming into the center of the spiral and the output coming out 
of the ‘nozzle’ part. It is mounted through the support for the rudder post 
(behind the post) with the exhaust going up to the starboard dorade. The blower 
is labeled ‘high capacity’, but I couldn’t get any numbers off – maybe when I 
can climb down into the lazerette and stretch out back there… But the 
likelihood of finding a duplicate is slim.

 

There’s a similar unit in the West catalog.

 

Good luck, Gary

Hey all, 

I'm looking for input on a good blower installation on my 1976 C 30 mki.  I'm 
almost through rewiring my entire boat and I'm up to replacing the blower.  I 
removed the the old unit because the fan motor was dead.  Judging by the look 
of it, it may have been original.  

The flexible hoses were connected to nothing, so I'm not exactly sure how it 
was originally hooked up.  Although I surmise it exhausted through one of the 
two dorade vents on the transom.  I assume the other dorade vent is used to 
just allow outside air into the engeine compartment - since there is nothing 
hooked up to that. 

I'm curious what the original blower/air inlet setup was on a 30 mki, and I'm 
I'm looking for the safest and most effective way to clear my engine 
compartment of gasoline fumes.  

Also, if anyone has opinions on the proper size (in CFM) of the blower(s) and 
the proper diameter of the flexible tubing I'd love to hear it.

 

Thanks!

Make sure the replacement is designed specifically for venting explosive

My 30-1 has a flexible hose of about 4 inches in diameter hooked to each 
dorade. I have a diesel, so am not as concerned about getting fumes out, so 
have put smaller vents where the dorados exit. One of the vent hoses is hooked 
through the blower. I will go over to the boat tomorrow and read the specs off 
the blower for you. I would guess that one of the dorades should point forward 
and that hose should just exit near the engine (mine does) and the one through 
the blower should face aft. It sounds like you have the original setup.

On my Viking i ran all new hose to the vents on the transom.  I used the blower 
to pull air out of the back of the engine compartment and attached the other 
end of the hose to one vent and faced its scoop aft.  The other scoop I faced 
forward and ran the hos attached to it to the front of the engine compartment.  
I figured that way I'd get the benefit of moving forward to continually add 
fresh air to the engine compartment.  It is just my own logic that came to that 
setup but, I never did blow up! Danny

You need to figure out if your vents are 3 or 4 inches. Buy a blower *designed 
for ventilating gas fumes* with the correct diameter and some hose. You want 
the end of hose near the engine as low down as you can get.

Hi Ryan,

Like most others, my blower (3" commonly found) exhaust via an aft cowl vent.

I don't recall anyone mention that gas fumes be 
heavier than air, so the intake hose should be as 
low as practical and below the lowest possible ignition point.

I have the intake laying alongside the aft port engine mount.

Cheers, Russ

My 1980 30-1 has two hoses connected to the stern vents. One hose is blower
exhaust, the other runs forward to just aft of the engine and sits there -
air intake. I turn the tops accordingly. Very likely this is original. The
hose diameter fits tightly on the vent base, so 3" I.D.?

My fridge compressor/radiator is in the engine compartment. I ran the intake 
vent piping to the radiator to get the cooler air. The exhaust vent pipe runs 
to forward lowest area of the engine compartment. I upgraded to 4" to Max the 
air movement and tried for a quieter exhaust fan. I run exhaust fan separate 
from the engine on hot days. There is also a initial PO setup for water cooling 
the compressor. The PO disconnected this. I want to try it again. The thruhull 
is there waiting for a pipe next summer. The cooler water of the North Channel 
is cool even on hot days.

almost through rewiring my entire boat and I'm up to replacing the blower.  I 
removed the the old unit because the fan motor was dead.  Judging by the look 
of it, it may have been original.

The flexible hoses were connected to nothing, so I'm not exactly sure how it 
was originally hooked up.  Although I surmise it exhausted through one of the 
two dorade vents on the transom.  I assume the other dorade vent is used to 
just allow outside air into the engeine compartment - since there is nothing 
hooked up to that.
I'm curious what the original blower/air inlet setup was on a 30 mki, and I'm 
I'm looking for the safest and most effective way to clear my engine 
compartment of gasoline fumes.

Also, if anyone has opinions on the proper size (in CFM) of the blower(s) and 
the proper diameter of the flexible tubing I'd love to hear it.

Thanks!

My anchor locker lid on my LF38 is cored and it uses piano hinges.  So, in 1983 
that was the standard in the Rhode Island plant.

Re: Stus-List Proper Blower Installation - 30 mki

2015-12-23 Thread Rick Brass via CnC-List 
My 38 was originally built with an A4. There are 2 4” cowl vents on the 
transom, with 4” ventilation hose routed into the engine space. There are 2 
blowers similar to the ones that Marek identified in his post mounted under the 
cockpit sole; one of these is routed to push fresh air into the engine space, 
the other to extract air. The inlet hose was terminated above the engine and 
fuel tank. The outlet hose was routed to the bottom of the engine space and 
just aft of the engine. Both blowers are wired to the same switch on the 
breaker panel, so they work at the same time to move air.

 

I now have a diesel, and a refrigeration compressor/condenser mounted on the 
forward bulkhead of the cockpit locker to starboard of the engine. In order to 
maximize airflow to the condenser (while still circulating air in the engine 
space), I have rerouted the inlet hose (cool air?) to near the bottom of the 
condenser, and the outlet hose under the side deck above the condenser. One of 
these days I may wire the blowers so they go on and off with the refrigeration 
compressor, but for the time being they are still on the same switch on the 
panel and must be manually activated.
