I'd like some opinions/experience on something please...
My Humber has an odd (you might say stupid) "feature" which is that the inside of the hull has a large "wet" compartment, with a bung in each end, one into the anchor stowage space (so you can drain that out I assume) and one into the bilge well at the stern. Not a problem so far ... but the problem is that there is no drain bung at the lowest point of the bilge, only where the trunk is attached which is four or five inches up. So it is not possible to drain the whole thing right out unless using the pump, though when I park it on the steepest part of the slipway I launch from I can get most of it out, at least until the next rain! So when it is left on the trailer with the trunk down, it ends up with four or five inches of water right the way through the boat.
It is presently mid winter here, and while temperatures usually go a degree or so below freezing at night and rise to 3-4 deg during the day, there is a possibility of a period of several days below freezing, and I am going away on holiday for a few weeks....
Should I be worried about the few inches of water inside the hull freezing and cracking the hull? I don't have anywhere to put it under cover nor do I have a boat cover so there is no way of draining it out and keeping it dry. I looked at it yesterday (there has been a bit of snow the last few days) and the water in the bilge was frozen, I think that will be OK because it can expand upwards if it freezes but am now a bit worried about the hull. I'm also not convinced the bungs are a good seal (they don't seem a very tight fit) so the obvious thing of draining it out as much as possible and putting the bungs in, may not work.
Freezing water inside the hull seems like an obvious problem (though the idea of having a drain bung at the lowest point also seems obvious to me!) so am I worrying about nothing?
has anybody had problems with this? don't want to come back and find my boat split in two
