Typhoon cockpit drains frozen;<(

Post by Jerry Hemmerle »

No boat cover, boat still in water(inner basin, bubble system working good). The mild winter forecast was just changed with eight inches of snow,preceded by and followed by freezing temps. The Ty is holding up great, except the drains are frozen. I tried cooked hot water to no real avail, also using a long screwdriver. Any suggestions to unfreeze the drains and keep them so with the boat remaining in the water. I like the late and early sailing.
Thank You,

Have you tried pouring anti-freeze into the drain?

Re: Typhoon cockpit drains frozen, USE SALT!

Post by D. Stump, Hanalei »

Jerry,
I wouldn't use antifreeze, I'd use plain old salt! Pour as much rock salt into the cockpit drain as you can and follow that with a little warm water. That should clear the freeze block. The salt shouldn't hurt anything, after all, that's what the system is designed to be immersed in.

Jerry,

In addition to the salt, which should work, is there a way to rig a temporary cockpit cover to prevent any further accumulation of snow/ice? Are there lifelines? Can a small tarp be stretched from lifeline to lifeline covering the cockpit? If so, you may have to rig an extension rod or something in the middle of the cockpit, extending from the floor to the tarp to keep it from drooping. I don't know anything about the Typhoon layout, but those drains need to be kept clear.

Good luck and don't stay out too long while frostbiting you little stinker. Just the mention of someone sailing in winter makes me jealous.

I don't know about the local temp there, but at Marina Bay on Boston Harbor, the salt water is frozen solid. There's always water in the hose from the drain to the seacock... if it gets cold enough, it freezes regardless of its salt content.

Re: Sea water salt concentration same as human blood...

Post by D. Stump, Hanalei »

Neil,
The concentration of salt in sea water is pretty low, and very close to that of human blood. Yes, sea water will freeze, as will a human body, but a very high concentration such as what would happen if you tried clearing cockpit drains by pouring rock salt in them, will not freeze! That's why our roads in New England are such a mess right now, LOTS of salt! Anyhow, I'd still try it instead of antifreeze, not near as toxic...

Are we saying that the antifreeze advertised as non-toxic is toxic? Ethelyne glycol is and propylene glycol is not as I understand it. Is that not correct? Boat/US and others sell two concentrations of propylene glycol, -50 degrees and -200 degrees.

I wonder if anyone has tried or considered more than I the pros and cons of using wiring such as if often used on roofs in the frozen north to melt ice at the edge of the roof or keep pipes from freezing. I wouldn't want to leave it unattended, but it ought to work if it could be wrapped around a frozen hose or inserted in an open hose, before it froze. It seems to me there could be potential for a very hazardous installation, so I doubt it meets any code, but they do bury wiring in the ground. Does anyone know of a version of heat tape that would meet the codes for marinas?

seawater is much saltier

Post by john churchill »

compared to blood the salt concentration is high. even with the remarkable salt concentrating abilities of the kidneys you still can't make a "water profit" by drinking it. blood is 0.9% salt. i don't know about seawater, but i recall putting about 7 lb of salt into my 55 gal marine aquarium to make it right.
not that it makes any difference in deicing your typhoon.

Hey Dave!

That sir was a gold star idea! Unless your temps are getting below zero, it should work well. I would love to hear the results though.

Re: 0.9% for blood, average 3.5% for seawater.......

Post by D. Stump, Hanalei »

John,
Ok, I checked all over, even with the medical department here at work. Basically "normal" saline and human blood is 0.9% salt. According to NOAA, the average salinity of sea water is 3.5%! So, you are correct, salt water is much saltier than blood! Average saltwater freezes at 28.5* F. But, as the saline content is raised, the temperature of freezing drops. I'd still fill the scuppers with rock salt, and follow that with a cup or two of warm water and see what happens. One site I found said that the Antartic seawater salt content is about 3 tablespoons per cup of water! Now, that's salty!

The next question is, How salty is the ice in an iceberg? Answer: It isn't, most icebergs are almost entirely FRESH water!

Hey, John, isn't it fun talking about "salty" stuff on this BB?

I started to repaint the dingy for Hanalei yesterday, so I won't have as much time for this as in the past......gotta get ready for Spring launch.....

Thanks to All you old salts,
I used Safe Step by Vigoro after talking with their tech people. I use this stuff for to melt snow in front of my house. It does a good job. It WORKED in the drains, some help from Manual Labor and hot water. The old floppy tarp is now in place, just in time for this evening snowfall.

Not seeing the salt for the sea,(leaves for the tree);

how's that saying go? "Success comes by right choices....
