Re: Hard Freeze Warning in Florida Areas what are you doing?

Yes, that lack of snow is nice, but it probably means low water levels on the Lakes this summer.

Oh well, boat show in two weeks. Can spring be far behind?

A serious reply

In the northern Chesapeake it does not go below freezing in boats kept in the water until the water temperature is near freezing and the low temperature about 15F. I generally only get ice in bottled water a few days each year. In the early winter, when the water is 45F, it will not freeze inside the boat at any realistic temperature. The water keeps the interior warm. With 70F water, I wouldn't give it any concern. I doubt the air will go below 45F, and it requires hours at 27F to do any damage.

I might drain drain a transom shower. Not anything in the hull.

Re: Hard Freeze Warning in Florida Areas what are you doing?

A few years ago, we had a hard freeze with a low of 22 degrees, which matched the car thermometer when I arrived at the marina at 6am. Bulkhead mounted boat thermometer showed 42 degrees (with no heat on) at 6am. Haven't worried about it since.

Wind is only a small part of the equation and irrelevant if the temps aren't below freezing.

Don't fret it!

If your really concerned, drain your lines.

A couple of days with dips below freezing does zilch to the salt water... which freezes a bunch of degrees below fresh water (think it is 4-5 without looking it up).

Re: Hard Freeze Warning in Florida Areas what are you doing?

Say, I was wondering... what's a hard freeze???

Here in the PNW it's when it gets below freezing and stays there for more then a day. IAW water puddles and leaves will freeze up.

Strange it was that high locally.

Calibration needed maybe.

It's that thing brains do in hot climates, mostly before air conditioning. Explains much of the 3rd world. And Florida voting irregularities.

Yes... and no.

My neighbor sank several years ago because he had a loop in a sump pump hose. The hose froze in the loop, the sump didn't get pumped, and 3 feet of snow did the rest. I told him about the frozen loop weeks before and he didn't react.

For those of you in FL, there is zero risk of freezing and breaking a through hull valve in FL. That takes sustained (day an night) sub-freezing temperatures for weeks. The seawater must be frozen below the fittings and the air must be very cold. in part, seawater tends to freeze soft, because of the ice.Others can chime in, but I doubt it happens in the lower 48 on the seaboard (lakes are a different matter entirely).

I will probably blow out the lines and leave the faucets open.. unless someone is certain its not an issue.
The ocean here is cold year around but really cold now below 45 F sort of cold. I goes below freezing parts of every winter but with the boat closed up to hold the heat from the ocean it's not a problem. With a cat I guess you get less heat from the water but your water being so warn it's hard for me to imagine your lines bursting.

A hard freeze means that annual plants are in danger. Really. That's what it means. It's a gardening warning.
