This drives the point home

My electric space heater is rated UL 1275 and double electric burner just says “UL Rated”, but it’s 1500w if that helps

Give us the wattage of the space heater and we can answer your question.

What happened was that the connection between the on shore power cable and the boat was singed so bad that I had to replace both the on board connection and the cord.

Not the same as Neil's topic on gas vapor safety but good fodder for another thread discussion... SHORE POWER connections.

• Power cables draped or running thru the water
• Turning off the breaker BEFORE disconnecting shore power
• Rusted, pitted, cracked connectors
• Improper wiring onboard many vessels (gauge, wire type, circuit breakers)

These are just a few of many that contribute to a recipe for a dangerous boat fire.
As I said, fodder for another thread discussion.
(maybe I'll start it)

Let's do it. It could be as exciting as talking about anchors at CF.

I'm a fan of the Smartplug myself.

But for now, to answer ndutton, the space heater is also 1500watts.

[ndutton]

1500W for the space heater, 1500W for the hotplate = 3000 watts. A single 20 amp circuit has a maximum capacity of 2400 watts. Pretty easy to see why the breaker tripped. The damaged inlet plug is a different matter. When the new thread gets started we will dig into it.

Done.

Diesel engine - propane in the BILGE

Diesel engine - propane in the BILGE

if it is sealed at the top (seems that there is a hatch and a lock) AND there is a vent line properly implemented to the outside... that could be OK.
Otherwise...
I have to admit that the video a the beginning of this thread and the boat completely wrecked up are going to make me take much much much more seriously the 1 minute ventilation procedure pre-ignition. I became somewhat complacent these last years, and probably let it shrink down to 30 seconds. Guilty!!!

Not even CLOSE. I know this because I had to redo a propane system on a boat that tried that and the surveyor said HELL NO, no insurance for you!
Those containers are nowhere close to being gas-tight enough to be safe besides for the fact they dump all the gas right into the bilge when you open the top.

Yes and no, there is nothing wrong with the idea, it just need to be well executed.

This passed the surveyor with no issue. Now filling that tank is PITA because all the new tanks need to be certified in the previous 10 years or less than 10 years old.

My boat came with a two tank store bought polysomething locker. It was mounted much like in post 22, in the cockpit locker. It has an above waterline thru hull drain, solenoid and 2 separate lines.

An insurance approved Annapolis surveyor (Stimson) approved the installation.

I can see that it is not perfect as if the top seal fails it could overflow into the boat.

Actually, assuming it's a slow leak and not a gusher, will just flow out the vent line. Now if it the propane is overflowing out the top... you have a condition.
