In the background, the traveling channel marker has been tied to the dock. I believe these are trumpeter swans (the yellow things on them are number tags).

The ice brought one of the channel markers into the harbor.

Heating System
Richard
Tue Feb 22 18:39:49 EST 2011

The heating system on Issuma consists of two drip-pot diesel heaters. The pilothouse is heated by a Dickinson Lofoten heater, which is also used for cooking (though most cooking is done by a gas stove/oven). The forward part of the boat is heated by a Dickinson Alaska heater (see previous blog entry).

Fuel for the heaters is gravity-fed from the daytank, through a fuel
filter/water separator. The drip-pot diesel heaters will not run if there is water in the fuel. A little water in the fuel will result in it boiling loudly as it enters the combustion chamber, and the heater might stay running, but with a lot of water in the fuel, the flame will go out, and the regulator needs to have the water removed from it (there are no drain plugs, so the way I've done this is to suck it out with a copper tube).

Between these two heaters, the inside temperature can be about 25 degrees C higher than the outside temperature, or about 20 degrees higher if it is windy.

This works well down to about -10C/14F (and not so well at -20C/-4F).

Previously, a wood stove was used. This put out a decent amount of heat, but had to be tended every hour or two, so, over the course of 24 hours, didn't put out as much heat as a diesel heater did. The wood stove was more suitable for heating when there are several people aboard, to share the task of tending the stove.

Do you use the balanced air system with a separate outside stack for the intake air? .... .. What happened to the Sigmar Heater? Did it work alright?
Wed Feb 23 7:04:28 EST 2011 | Richard Hudson
Neither Dickinson heater has a balanced air intake, so both are drawing intake air from the cabin.

The Sigmar 120 heater I used earlier had the ability to draw air from outside, but I never configured it that way. I ran that heater both in the location up forward and in the pilothouse, and it worked well in both places, but just wasn't big enough for heating in winter. The balanced air intake pipe that heater had on the bottom did pull quite a bit of moist air out of the bilge, and was a nice feature.

When I replaced the Sigmar 120 with the Lofoten, I tried installing the Sigmar in the bedroom, for use as a third heater for when it was really cold. I used an existing vent hole in the centerboard trunk for the chimney, which involved two 90 degree turns, and the draft never worked out. It would work if I put the chimney thru the deck, but it was a temporary install for use in -15 to -20 temperatures only (otherwise it is too big a heater for the bedroom), and the cold weat

Forgot to mention, I originally bought the Sigmar 120 heaterpartly because of the balanced air intake, which I figured would help in getting it working properly under sail.

I abandoned the idea of getting either of these heaters working under sail. Neither chimney location is free of downdrafts while sailing, and both have high stacks, which prevent backdrafts, but also get in the way of sails and lines if trying to sail with them.

While it would be comfortable to have a warm boat while sailing, no heaters are really reliable (diesel heaters stop when out of fuel, or too much water or dirt in the fuel, or when chimneys fall overboard), so one always needs sufficient clothing for the temperatures one sails in. Not having a warm cabin when sailing results in wearing suitable clothing for the temperatures, so isnt a real disadvantage.

looks warm and delicious. ready for spring yet?

I am more than ready for any weather warm enough to melt the ice around the boat that is keeping it stuck at the dock :).
Forward Heater
Richard
Mon Feb 21 18:48:48 EST 2011

The Dickinson Alaska heater in the forward part of the boat. This heater puts out about half as much heat as the Lofoten heater in the pilothouse.

There are 24 volt (Issuma's electrical system is 24 volt) computer fans on the wall that blow the warm air off the chimney into the boat. The plywood wall is covered with sheet aluminum to keep heat away. A strip of aluminum foil is hung from the ceiling to reflect heat back into the main part of the boat (this is only used on cold days in the winter at the dock).

Not shown in the picture is a barometric damper, which injects room air into the chimney, so less heat is wasted going up the chimney and out of the boat. Putting in the barometric damper made the heater put 30-40% more heat in the boat than it did when running without the barometric damper (this is partly because there is a tall stack--about 3m in total).

To be installed soon is a grating that protects things from touching the hot chimney.

The red nun buoy in this picture is much easier to recognize than the one in yesterday's picture that was loaded with ice. This buoy is around a bend in the channel, so it doesn't get the breaking waves that the outer buoy does...I believe that is why it is not covered in ice. This part of the channel still gets swell coming in, which breaks up the ice.

Below and to the left of the lighthouse, what looks like a floating piece of ice is actually a red nun (buoy with a pointed top), marking the entrance channel to the harbor.

It warmed up to -10C (14F) and got windy last night and this morning. This is the entrance to the harbor where Issuma is. The waves broke up the ice a fair way into the harbor, but not as far as Issuma, which is still frozen into the ice.

Your current scenario is very Endurance-like. At least you don't need to resort to eating only penguins. Although I hear you can cook ribs quite effectively aboard.

I'm finding it difficult to write about sailing while frozen in the ice and not sailing :). Fortunately the boat is in no danger of being crushed by pack ice, as it is docked in a very well-protected harbor.
Cold Water

Outside the harbor yesterday, when it was cold (-19C/-4F). The misty areas of the picture are steam coming off the water and steam from the spray when the water hits the ice-covered rocks.

Today it warmed up enough to snow (for those not used to cold climates, snow requires clouds and clouds reflect heat back to the surface, so the coldest temperatures happen when there are no clouds--ie when it is not snowing).

Thanks for the link, Brian. It certainly is surprising to see so little ice in Nain harbor in January.

warm greetings from the frosty south, dear Issuma!

Thanks, Christina. I see NYC is in for freezing rain tonight. Hope you are warm and dry.
