JohnRPollard - are you out there?

Use automotive windshield wiper fluid and potentially even the bottles it comes in. That fluid doesn't freeze and it's cheap.

Sand, if there is any moisture in it at all, would still freeze into nice bag shaped rocks. 6-7 gallons of antifreeze is cheaper than gel coat repairs.

Chuckles, Good point.


Kwaltersmi,

I like that alternative wiper fluid suggestion. Too bad they don't sell it in 1/2 gallon containers -- that would be about the right size. We'd need about 20 or so containers. Of course, we'd still have to store them for the summer, but there doesn't seem to be a good way around that....

Thank you all for the suggestions.

They make water bags to hold down winter pool covers that you should be able to use for this purpose. Add some anti-freeze and you should be all set for the winter.

no offense, but i don't get all these covers you see on boats. shrink wraps, tarps, canvas covers. Just down the dock a fellow built this enormous cover out of 2x3 wood framing and poly. fiberglas and stainless should not be harmed by rain/snow, and if you have water coming in, something needs fixing. i wouldn't think a boat should need "protection" from the elements, except maybe uv. what am i missing here? i guess if you have a lovely old varnished classic, but that's not what i usually see wrapped up for winter.

Um, I believe you started a thread on bird poo stains? 'Nuf said.

The problem Hoff, is with capillary action wicking water under and into any spaces occuring between mated components. Under normal - above freeze conditions, there is no problem. The water will simply evaporate, or eventually drain out and not result in internal leaks.

As this water expands however, these mated parts are at risk of separating, possibly compromising the fastener's hold - even ripping a section of GRP or teak away in the process. Now you have a water intrusion issue with cored deck, into cabins below, or frost heave of teak decking. I don't have coring, solid glass under my teak decking. But I cover to protect everything else.

If you're going to use anti-freeze I'd recommend that it be of the R/V variety and not windshield washer solvent or auto antifreeze varities. The latter two are toxic in nature.

If you can find the swimming pool tube weights you might be able to place a grommet in each end and then use each tube with a tie down line 4-6 feet apart.
