33 foot steel
mono down to Cape Denison, Commonweath Bay. Lots of ice there, more now since the Mertz glacier tongue broke off and blocked the whole bay! A catamaran
went down there in 98. Look up Ice cat. They didn't quite get into the bay, and had to run off unfortunately. It's much colder down there than the peninsular (near Argentina/chile) we had a taylors diesel drip heater on her that I only used for a few hours to conserve fuel
. 45mm polystyrene insulation
throughout the cabin
, but not the lower hull, so cold feet.
The other boat was an aluminium charter
boat I skippered down to the peninsular. It is pretty warm there in summer seldom much below zero deg Celsius, and you could happily get by without any heating, just warm clothes and good insulation.
But any heating makes life much more pleasant, less damp and condensation
, and you can dry clothes properly.
If I was setting up a cat without big budget
constraints I'd have a dickenson lofoten up in the bridgedeck, (or a Refleks) with the hot plate for cooking
and a good drying rack around it for socks and gloves. In each hull I'd have a webasto type heater blowing warm air into the cabins below. Ideally both engines would have an extended coolant loop or some such through the hulls you heat them when you are motoring, maybe with a drying cupboard near each engine
blowing hot air through it to dry wet wx gear
With a setup like this you should be toastie as long as you have the diesel. Just as a comparison we burnt most of our 1000 litres per 24 day trip. But we rushed about a lot and had to make the most of the settled times by moving.
On my little boat I burned about 1/2 of our 300 litres motoring through the pack ice. I kept a lot in reserve for getting back out. The pensular by and large doesn't have a big ice problem. Lots of small broken up brash, but not so dangerous to a metal hulled mono. A foam core
cat would have to be much more cautious. A solid grp hull is pretty tough.
