Re: how do i make it warm

Heating on a boat is one thing a person shouldn't cut corners on, budget or no budget. Just remember, that dying doesn't cost anything either, so before you go burning something below, make sure it was designed to be there (i.e. it's vented properly). Outside of that, dress in layers.

Re: how do i make it warm

Dude I understand the budget limitations, really I do. However, cobbling something together that uses an open flame, burning who-knows-what for fuel, in a sealed cabin is a recipe for disaster. You'll either gas yourself to death or burn the boat down to the waterline.

You're up against some hard limitations:
1. You'll eat up batteries fast, using them to power any kind of heater.
2. You have no means of charging the batteries anyway.
3. You have no money.
4. You have no supplies.

This leaves you with needing some kind of SAFE, flame heat, and needing donations.

Using a stove for heat works poorly because the heat is concentrated at a single point for cooking, and not circulated around the boat.

I recommend you check here:
Freecycle.org
Someone may have something you can use.

If you can get a small gift of cash, I recommend these:
Origo Heat Pal
Coleman Black Cat Heater

The Black Cat is great because it's flameless and the exhaust is catalyzed so you won't gas yourself. Just make sure you have an adequate flow of air into the cabin so that the oxygen level doesn't get too low. I doubt your cabin seals that tightly anyway.

The best option would be to get to a dock that has 110v ac power and use an oil-filled electric radiator heater. They cost about $40.00.

I would want something that can be run while sailing, so you could go down below to warm up periodically and therefore extend your sailing season a bit.

I am unsure how the alcohol heater can have 5000 btu's but the propane only 3000... and which would be safer...

So the black cat doesn't release CO and CO2? You can't gas yourself with it? How is this possible?

Re: how do i make it warm

Slightly off topic but necessary info:

"Women tend to be more expensive.
A good Lab will dive into frigid water to fetch a stick, haven't met a girl yet who will do that for me. "

A good test is to lock both the woman and the dog in the car trunk for a few hours. When you open the trunk note which one is happy to see you. Keep that one.

If you are going to burn stuff in the cabin to keep warm get either a carny bird or a CO monitor. You don't want to wake up stiff.

As I said, it's a catalytic heater. It uses a sort of catalytic converter to convert CO into CO2, and the CO2 is kept at safe levels by ensuring an adequate oxygen supply. The effect is similar to what happens in modern car exhaust systems. I'm not saying it's harmless and to abandon caution. I'm saying it's safer than a lot of other options.

Well if you want to be cheap and stay warm just go find loads of plastic and wrap your boat. It creates a greenhouse effect.
Of course, once the sun goes down..

Re: how do i make it warm

FIRST OFF To have have HEAT and NO Carbon monoxide (CO) Detector is just INSANE and STUPID

As it just got cold here i am expecting the first death by CO any day now in the paper as we get them every season on land and water

If a dirty bottom slows you down what do you think it does to your boat

Re: how do i make it warm

I know there is a guy who sails his modified 22' boat from the northern UK to greenland, iceland, and the arctic almost every year. He has no heater in the boat, but has insulated it with the pink foam stuff and that is enough to keep him warm in the arctic. Very small, heavily modified boat, but still the insulation has to help... not $0 though haha...

Re: how do i make it warm

The catalytic process produces water vapor, could there be a moisture issue there?

I had a leaky propane bottle in my boat one time, I was able to smell it and discard it but these things do happen. Would a CO monitor, kept low in the cabin, be able to detect leaking propane gas before it builds to a dangerous level?

Re: how do i make it warm

Fires are problematic and "cheap" rules out fuels in general.

And forget any kind of alcohol heater, the amount of water vapor they product will be truly memorable.

I'd really suggest layering up in some warm clothes from the thrift store. A good wool watch cap (or two) and insulated boots, moisture-wicking long johns, and you've got the safest cheapest solution.
