A man would need to use great care if you are below the water line and trying to drive a plug in. NO BOAT IS WORTH A LIFE. if you are miles from land risk factors change. The loss of the boat might be a huge loss and change the odds of making it. If you are at the dock the game is all about you. Maybe the dock lines would hold her up?
I can tell you as a pipefitter I have used a wooden plug to stop a 2" inch opening off an 8" pipe with glycol/water mix at about 40 psi the nipple was broken fitting off by a fork truck. The factory needed to run until shift change a cut and weld could be made.
The plug was drove into the hole with the pumps off. With the pumps off their was very little head pressure. I was expecting it to shoot out like a cannon and the mess to spread but it held.
I have changed a 3/4" inch thermal well at the basement three floors down on a 6" condenser water pipe. This was beyond wet No garden hose has that kind of pressure. It was chilling. I am still amazed that I was able to thread in a new one. If I failed on that one It would have cost a day or so but everyone new the risk. I would not have used a plug We had made the decision to open the main drain If I failed. Picked the day and did it.
If you had to have a reaction on a boat . I am not sure you would have time even if the plug was on a string next to the opening with a hammer at the ready.
Good day, Lou
And what kind of water pressure do you expect from a broken seacock 18 inches below sea level?

Have a look at these two videos..

Re: Extreme Cold

Sprayed closed cell anti microbial insulation foam works. But shaving it to "size/fit" is a b,,, Yet worth it! it comes in two five gallon pressurized tanks!

I always sailed in the winter if the ice did not preclude me. Have woke up many times in ice,,,no problems, winch in your anchor through the inch of ice! As you motor forwards,,then back out till you reach, the inlet. Li/NY

OH! HUGE THING! VENTILATION IS B> I USE AGA Mask.

We've bubbled boats for as long as I can remember. At least 40 years here on Lk St Clair.

I'm talking about a few hearty souls who are actually living aboard a few of these bubbled boats. Go figure ?

Oddly enough, I just watched this one a few weeks ago and then watched the one where they turtled a boat to see who much stuff flew around inside.

Re: Extreme Cold

I can see one minor drawback to H2Out marine products:

"How to regenerate your H2Out Dehumidifier:
Simply place the unit in an oven* for two-three hours at 300F (149C). - See more at: http://h2out.com/faqs#sthash.tawcp1wL.dpuf"

So who is going to run the oven on their boat for 3 hours every day? In order to...drive the moisture out of the H2Out and back into the cabin of the boat?

Just seems like an electric heater (goldenrod) or ventilated heater (external combustion) is a way more effective way to go.

Re: Extreme Cold

Apparently we had an ice storm last night. It was raining a good bit in the afternoon and all of a sudden the temps dropped and left a thick layer of ice on everything.

We have over an inch of ice in places on the boat. The expected temps in the next few days, aren't going to be enough to melt the ice I don't think.

We chiseled the ice off our vehicle and attempted the snow/ice covered hill out of the slip parking. I barely made it up the hill and as steep and narrow as that drive is, I would not attempt to come back down it.

As for the boat, I wish the weather man had been able to predict this so I could have covered the cockpit of the boat. The hatch was frozen shut this morning and it took a bit of work to get out.

There's even a live aboard community here in Minneapolis, on the Mississippi river. Houseboats, not sailboats, but yeah all year long. And it is *cold* here.

Re: Extreme Cold

When I was living aboard (Toronto winters). Some people would hang a 60 watt bulb and fixture next to each through hull to keep then nice and warm over the winter! I did this for a couple of winters and then realized that this technique wasn't necessary with the bubblers in our marina! The system they used had massive compressors and the entire slip would stay ice free.
