The more I get into designing the new interior of this '68 Chris Craft
Corsair I want to turn into a winter boat, the more I get to wondering
about different things. One of which was brought home this morning as
I took the dogs out for exercise.

Having arthritis, cold isn't my friend. Adding to that, I don't enjoy
the cold all that much - never have. I tolerate it, but I don't like
it. Therefore, it is paramount in a winter boat to have....

HEAT.

My thought was to pull heat off the engine much like the radiator
system in a car. The way the design is developing, there will be an
interior cabin of a sort or at least a place where one could get out
of the wind, rain, etc. Think of a Parker/Steiger type pilot house
without the adjoining cuddy space. This is where I would put the
heating unit.

I'm just not sure this is a valid way of heating this small space.

Any thoughts?

Later,

Tom

I probably missed a bunch about your plans. Is the heating requirement
while underway or at the dock? It would seem that underway you are
limited to whatever you can generate by capturing engine heat or that
available for conversion to electric by the engine and/or generator, if
equipped. A set of quality and heavy thermal underwear will help. :-)


If the heating requirement is at the dock, more options exist.

I haven't really talked much about it because it's been in the works
for almost a year. I've just finished up the design now - hobby, get
all the ducks in a row, before I start kind of thing.

It's more of a "let's get the temperature up to the point where I can
warm up" kind of heat while on the water. I don't intend on having a
sauna in the pilot house. I mentioned to Harry that the space is about
the size of a town car and the required temperature would be about the
same as it would be in winter traveling in a car.

Here's another thought. How much heat can I obtain having a fair
amount of eisenglass using solar heating?

If the heating requirement is at the dock, more options exist.

Nope - this is strictly a trailer operation for cod in Boston Harbor
or winter flounder off the Westerly Reef. Weather gets snarky, I'm
outa there. :)

Take care.

========================================

Small commercial fishing boats have been using engine coolant heating
in the cabin for a long time. There are a lot of variables. For
example, the closed cooling side of a FWC engine will typically have
the highest available temperature (160 to 170 F), but a raw water
engine wouldl have a lower coolant temperature.

My former Bertram 33 had a full flybridge enclosure (lots of
protection but somewhat drafty). We used to run in cold weather
using just a 1500 watt electric heater. It was comfortable in
temperatures down into the 30s. You could do something similar with a
lightweight Honda generator on the back deck. They are very quiet and
it would have other uses. I'd get a battery operated CO detector for
the cabin in any case.

I didn't know that. When I was a kid, the lobsta guys used old French
made coal stoves in the cabins - they could keep the heat low and just
ticking over to keep the chill off.

One of my favorite memories was sitting off Baker's Island with one of
my high school buddies and his lobsta fishing father eating a fresh
made chowdah in the cabin of the lobsta boat.

That's a thought, but it's only 20 feet long - I'm trying to avoid
using a small generator, although I do have one.

I looked into engine heating when I had my 20-footer, and it's pretty easy
(What kind of engine do you have?) You just "interrupt" the bypass between
the water pump and the thermostat and take it to a radiator. Same system
as a car.

I suspect you can do the same as what's in my van: two radiators in
separate locations. Works pretty well.

Alternatively you could use any of several portable or built-in propane
heaters, like they use in RVs. The portable ones are OK as long as you can
tie them down somehow and have ADEQUATE VENTILATION

Thanks for the info. Appreciate it.

I have one of their "1H" models in my ski boat. Works great! Even in a
totally open ski boat you can get enough heat out of the vents to keep the
driver warm and toasty. The vents pull out and extend on hoses and you will
often see the observers covered in a blanket with the heater vent tucked up
underneath keeping them warm as well. I am sure that if you had any kind of
enclosure you could get enough heat to keep the cabin reasonably warm.

You have to be running, of course.

If you want heat while the engine is off then I would recommend a small
portable propane unit. I have a propane heater similar to this one:
http://www.mrheater.com/productdetail.asp?id=675 (the double head) that I
used to heat the flybridge of my 36' Carver. I never used both burners at
one time on the boat, and often I had trouble getting turned down low enough
so that it didn't roast us out. If you use something like this take extra
precautions that it is tied down and can't possibly tip over.

Rod,

That little "1H" unit would work nicely on my boat too.
Approx how much did it cost?

Mine came with the boat, so I don't have first hand experience buying them,
but here is one online that I found:
