The heavy weights they use to anchor the docks have to come out too.
Just so you know what I'm talking about, this is Meaford's harbour. The Bighead River drains in from the lower left and out into the bay on the upper left. With the northwest winds blowing, ice from the bay can get pushed right into the river mouth; in comparison the marina on the right is almost completely sheltered from those winds and the ice. So it's the docks on the centre left that have to come out. Ice does very little damage simply by freezing; it's the pack ice being blown toward shore that does the damage, with the force of the wind behind it. Of course the big outer breakwall is the main protection against the ice. Without it there would be be no harbour here at all.
The temperature actually rose in the night, to nearly 10°C, and almost all our snow vanished in the twinkling of an eye. This view was mostly white still yesterday.
