I wonder what would be the best and most economical kettle to use to boil
water while cruising.
For year I have used an aluminium enclosed kettle with a whilst on a Origo
non pressurized alcohol stove.
I did not any better ( and still do) and was satisfy with the time to
bring water to a boil, the pouring and the filling.
Today I am looking at propane and the purchase of a new kettle and I
wonder what would be the best buy?
On a long cruise/crossing the more time it takes to bring water to a boil
means more propane.



The kettle you've been using should work just fine. Personally, I prefer
stainless steel, and I think you'll find that it retains heat longer than
aluminum, but to each their own.

Thanks for your feedback. My old kettle has been banged around in heavy
weather and still works. Over the years I learned that with the aluminium
kettles they tend to leak at the bottom seam after being banged around too
many times.

Yesterday, I made tests and learned that my home GE electric kettle boiled a
1 quart of water in four minutes and 30 secs.

The expensive SS Langustina with a thick bottom plate did the same at max on
our electric stove top in seven m and 18 secs. The Canadian Tires SS kettle
with thin bottom boiled the 1 quart in eight m and 38 secs.

Testing on propane or alcohol would give different results in timing.

To compare the load:

That pot probably draws 1500 watts divided by 13V = 115A x 4.5 mins = 8.6
AH off the battery capacity to boil 32 oz, 2 pots in the Hot Shot.

1.45 x 2 pots is 2.9 AH compared to 8.6 AH. I think the disparity is the
very low thermal mass of the Hot Shot's boiler, directly coupled to its
fast heating element outside the boiler under it. The boiler is very thin
aluminum with automatic shutoff thermostat. (You reset the thermostat to
boil the next load.) The kettle, on the other hand, probably has an
internal calrod metal beast to heat up along with all that exposed metal of
the kettle itself before the water's going to boil, a much bigger thermal
load.

The Hot Shot's boiler is also insulated by the plastic case around it.
It'll keep water at near boiling temperature a long time after it shuts
down.

Our rec.boats.cruising thermal engineers will be working on this problem,
day and night....(c;

You can tell because none of them ever called Earth.

When I had diesel engine problem I bough a 12 v, 700 cranking amps, 22 Ah,
20 pounds mobile power pack at Canadian Tires.
It works fine to start an engine and to operate a radar and GPS when the
main batteries are dead.
I wonder if I can use this Power Pack to operate the Hot Shot's boiler?
Using an estimated wattage consumption of 9 watts for a radio or dept finder
it will last approx. 24 hours. They say for 110v power an inverter is
needed. As an example they say a 100 watts light will last an estimated 2
hours. This power pack is rechargeable using a 12 volts receptacle. The
continuous charging time is normally 24 - 72 hours. Well by the looks of it
this power pack may only be good for emergency. Plugging the inverter
directly into the 12 volt circuit system appears to be the best way to do
it. Or the power pack could be connected to the boat electrical system on a
permanent basis?

Most likely, the power pack is NOT a deep cycle battery, and would suffer
greatly from being drawn down that much. Its purpose is to provide a short
burst of power to start your engine, and ONLY that. If you want to go
electric with another battery, you'd be much better served by adding another
deep cycle battery, 100 or more amp hours, to your house bank.

Good observation "You must drink an awful lot of coffee to make such
experiments worthwhile. "
We drink on average 2 to 3 cups per day. The issue is fuel. With my
existing boat I can only carry so much.
We cruise the St. John river system, Bay of Fundy, South shore of Nova
Scotia and the State of Maine. The Marinas are few and far between. They
do not always have alcohol or propane. During the hot summer months a non
pressurized alcohol stove, even when not in use, will lose fuel by
evaporation. Hopefully I will have two ten pounds propane tanks on board my
next boat.
