Argh!
I'm frozen solid. It started almost a week ago when the bubbler system wasn't switched on overnight. Usually when that happens we switch on the bubbler in the morning and within a few hours the bubblers manage to erode the ice from beheath. However, it seems my bubblers are slightly lower in the water - they're hung from the gunwhales by nylon packing strap material. The lower pipes suffer as the air pressure seeks the easiest path - the holes closer to the surface - unfortunatly for me, those holes are all around my neighbours boats.
Before you go and suggest that I simply raise the lines, its not that simple. The nylon will simply break where it enters the ice, and the ice is now over 2" thick. I lose them, I'm screwed to retreive them till spring. All night the temps drop and I listen to the grinding sounds against the hull as the sheets of ice shift - very unnerving, especially if it's your first time hearing it. This is my fifth winter, so hardly the first. I have a fibreglas boat, built in the 77, so the glass is fairly thick, but still you can't help but wonder just how much she can take. In the end, the ice will win.
In the end, it will be the sun that will help the most. We can try to put in an agitator, but its difficult to get it close enough - no open water around my boat. We're well past being able to rock the boat free. We've tried pumping up the pressure - all the way to 75 psi - doesn't change it for me - the air still takes the path of least resistance.
Ok gang - any ideas? Ya gotta admit - at least this one isn't boring. LOL
Thanks in advance of your helpful suggestions.

I really have no solutions for being frozen in except wait till it gets warmer or move to a warmer climate. Sorry, had to say it. ;D But if it will help you pass the time away, we have been sailing off and on for the past month, even in the middle 40 degree weather we had yesterday along the coastal waters of North Carolina. We had some friends up from Florida that really enjoyed the nice weather, even though I did loan them a hunting boggin to protect a balding spot. :)

Wow, two inches thick? I was gonna suggest running a hose and using running water to try to melt the ice nearest the hull and then rocking it. Seems like if you broke a hole in the ice first you might be able to work your way around the boat....
I was frozen in here in NC twice. Both times the ice was less then 1/2" so it was really more of a novelty then a problem.... I just motored out of the slip to break it up.
Good luck!
I guess my reply was not too helpfull. Sorry. I have also heard that we maybe getting some of that nasty weather this weekend. But its almost springtime, even though March is unpredictable.
If it getting above freezing point during the day, how about a kerosene heater with a blower, like they use for pre-heating small airplanes in the winter? Maybe you can borrow it from your local airport? Or try just a shop kerosene heater first? Some of them are cracking nice 90k BTU.
If you have the bubblers running... it might be worthwhile to drill/punch a few holes—say a dozen or so—in the ice around the hull of your boat. a few inches out from the hull. Doing that will allow the air to bubble up and hopefully melt the ice that has formed. A series of 1" holes would probably do the trick nicely.

His bubblers are plumbed on a common air supply hose as his neighbors, they are lower in the water then the others, so no air will come out of them. At least that is what I get from this.
Maybe if you just use hot water to melt the ice around the straps that hold the bubblers, and then raise them?

Hot water at the place where the nylon enters? Then raise once freed

Great minds think alike. ;D
yeah- how about boiling (or close to it) water from a garden sprayer? Set the nozzle for a single stream.
Then in the summer you can convert the sprayer to a boat shower-
Double duty ;D
Of course except for ever 10 or 20 years the only ice we see is in trays ;) so what do I know?
You guys may not believe this - but hot water freezes quicker than room temperature. I have no idea why but it does.
All good suggestions - but each presents a challenge. The boat is enclosed in a shrink wrap plastic dome, which travels down the hull by more than a foot. 2" is not enough to support weight to walk on it - ok, not my weight and my dinghy is also frozen in. Getting at the straps is difficult at best.
At the end of the day, I think I have to hope for warmer weather soon = sunshine would be nice - and then raise it when I can. Eventually I can rock it free though this also risks breaking the nylon lines and sinking the pipes. May already have a few broken from this - can't get close enough to tell. Adding to the problem, I am stern in on a 22 ft finger - they are the closest to shore, so I can't walk out very far.
Welcome to living aboard in the Great White North. This is the last winter here - next year its the Bahamas!
Thanks again for all your suggestions

Here is some Grog for you John,
If the suggestions don't help maybe that will. :P
Think Spring! ;D
Oh Boy
Around here, the marinas usually have a work boat bust up the ice before it gets too thick, in addition to the bubblers
I think the boat will be fine. I'd make sure all the seacocks are closed. Hoping the're bronze

Okay, so get a LOOONG mop handle, section of 2x2, 2x4, whatever. Pile on top of it some salt. Slide it out onto the ice alongside the boat. When stretched out, tip it to dump the salt. Repeat as necessary. This might soften things up enough to at least get you started, and you never have to leave the dock.
A garden hose running water into one spot WILL erode ice.Could you run it where you need to long enough. You would be surprised how 'relatively' fast it works down. From one 'canuck' to another ; ;)
Hot water usually freezes faster because of two reasons... One, it tends to lose heat very quickly, since heat loss is dependent on the temperature difference IIRC, and two, it tends to have less dissolved gases, which means that it has a higher freezing temperature.
Try freezing seltzer water and plain tap water...and see which freezes first.
Last resort is asking the local weather goddess for warm weather... I'll put a word in with mine...but she's here on the east coast... ;)
