If You Are Cold, They Are Cold

So did those boats sink because of the weight of the ice, or was there a storm before the freeze?

It was the weight of the accumulated ice. That **** is heavy.

A few years back a crab boat was moving through a storm in the Gulf of Alaska, the ice build up got worse and worse. They turned into a bay and the turn sank them in an instant. Investigation found that the force of the wind acting against the boat was holding it upright against the weight of the ice on the windward side. When they turned the force of the wind was lost and the weight of the ice took over. IIRC a few of the crew survived.

The boats in the background have no ice on them, so something must have been spraying water on them for a while, maybe a burst pipe?

Yes, I know. But Heifers Made Warm did not fit. 

And you just don't know, she may just go warm up the farm yard bull afterwards.:dunno:

So she's a high-efficiency 2-stage heat exchange unit. Probably high-μ :)

("unit" is such a great way to add bulk to one's writing without saying anything. Adds credence like a British accent.)

I don't know the specifics of what happened in the photo. But, I have seen situations that were similar, and in those the boats that got ice were closer to the breakwater. Waves were crashing and splashing and causing spray that only carried a couple hundred feet. Boats on the other side of the marina and those under the covered moorings were mostly ice free.

One time I saw 4' of snow on the covered marina and the roof partially collapsed, the boats under it were holding up the roof. Crews were working to try to save the boats and get the snow off. In the end they used a fire hose to wash the snow off, pumped the water out of the river. It worked pretty well and they didn't have to put guys on the failing roof.

Is the weight buildup the problem with icing on airplanes? Or does the ice interfere with the lift and control surfaces? 

Ice on control surfaces reduces lift and causes erratic, sometimes unexpected handling in the air.

Often causes aircraft to go from flying to falling.

And, to answer your question that you didn't think to ask, supersonic aircraft do not include on-board de-icers, such as the expandable boots along the leading edges of the wings.

Like any other aircraft they are de-iced on the ground prior to launch, but once aloft, if ice forms on the control surfaces, they just put it in third gear and the ice departs the aircraft.
