Do you have them all on in the cabin at once? That would be nearly 3kW...

Interesting report here:
http://www.cpsc.gov/library/foia/foia05/os/co03.pdf
After reading this I would'nt use a catalytic heater in a boat, although I have used one one in a caravan awning in the past and would do so again

Interesting reading - the box used was only 6' x 4' x 4' and completely sealed! And even then the peak readings are only just over the limit...
I think most cabins are well enough ventilated, as well as being a much larger volume. Even so, I turn off my Vapalux and catalytic heater before retiring for the night...

I live onboard and have done through this moderately mild winter, and all i use is a 2 season coleman cotton lined sleeping bag (cost £25 about 4 years ago) and a £4.99 tesco 11.5 tog single duvet to go over the top of the sleeping bag when its cold, I have been kept toasty warm in down to -5 degreesC this year using the two together, and as seajet said, if its really cold, you just pull the duvet over your head leaving a little gap for fresh air to get in, and you will be breathing warm air and be kept toasty warm all night

Four ideas/observations:
1) We occasionally use a mini-catalytic heater in our little boat, and find it a real boon. They are claimed not to emit carbon monoxide, which is the killer, but of course you do have other combustion products given off including water vapour, and if you realy have no meaningful ventilation you risk running v low on oxygen (heater will shu off but so might you!). Our boat is well ventilated, so it has never been a problem, even when I fell asleep one night with the heater on.
2) Aside from the heater, one trick I have found amazingly effective is sitting with a blanket doubled up over and around my legs when sitting in the cabin. The coldest air is at the bottom of the boat, and I find it makes a really surprising difference to how comfortable I feel when its cold (and without said heater on).
3) A liveaboard friend built an impressive heater contraption to go on his gas cooker. It is an upturned brass or copper pan that sits on the burner, out of that comes a tube about 4" dia other end of which pokes out of a similar sized opening port to exhaust the fumes/moisture outside, and a series of brass or copper plates with holes in the middle the size of the tube fixed (brazed?) onto it to conduct the heat away from the tube (to the extent it is virtually cold at the upper end before it gets to the opening port. Gives off a goodly amount of heat without fumes.
4) Combine any or all of the above with a cuddlesome shipmate!

No, now got a very effective Eber
. But I used the Tilley in a previous boat and I sometimes use the 2 vapalux in a tent nowadays.

Another idea is to use cheap tealight candles for heat and light, i've been experimenting with them as they are £1 for 100 of them in the pound store, and 15 of them alight at the same time produce enough heat to get my cabin to 17 degrees with an outside air temperature of 8 degrees tonight, and my CO monitor has been hovering around 12ppm for the last 2 hours with the candles alight, so well within guideline figures

When on shore power I use a 800watt oil filled radiator and once the cabin is heated I leave it only half on (400watt) and it cuts in and out on the thermostat.
