guys,
my solution is probably unique and not widely applicable.....i keep
a 110 ceramic heater on board from oct to may....with my (upgraded)
hehr alternator, i can run and provide for it without any draw....this
is one benefit of the 350 i/o....also, if it is bitter cold, i can plug in at
a marina for the night.....at 1500 watts, it makes the cabin very, very
cozy indeed.........if i run the heater on shorepower all night, keeping
it 65F constantly for 12 hrs, then run with it on, the time i might have
with the engine off is quite tolerable; if the HULL falls down to the 30`s
then the cabin gets a "deep" chill which seems bone-piercing, but if the
hull and contents start at 65F, they provide a while of residual comfort...
in the winter, under the tarp which is open at both ends, i will use
a catalytic heater "......pal", but i would never put any fuel burning
device inside.......by the time you get adequate ventilation, you have
damn near offset the the heat!....at the very least, PLEASE INSTALL
AND MAINTAIN A CO DETECTOR IF YOU USE A PROPANE UNIT IN THE
CABIN.....they are cheap and reliable...........dan
