"hooked it" from "sling one's hook" - to move away
The web tells me the derivation is obscure -
"There are at least two theories. One equates hook with a ship’s anchor, so that to sling one’s hook was to raise the anchor and sail away. The other says the hook is one on which a miner would hang his day clothes. When he finished his shift down the pit, he would change, collect his possessions from his hook, and leave. The second of these sounds much less convincing than the first, but the essential early evidence isn’t there to decide between them." (from
