Parbuckle is ... what I get when I ask my husband for a word of the week suggestion. He reckons it's topical because it's been in the news (as a way of righting the partly submerged cruise ship Costa Concordia). A parbuckle is a rope or sling used to raise or lower casks or other cylindrical objects.
When used to right a ship, I suppose parbuckling is the opposite of careening. I used to talk about careening in my day job, but as I don't do it any more, I'll spare you the details. When not used in a nautical context careening means to swerve about.
Here's a picture of a ship which, sensibly, stayed away from the rocks and therefore remained the right way up. I careened (slowly) up a nearby mountain to take the photo.
That's two weeks this month I've done a double word of the week. I must get a grip.
