Whaledown Crack Direct

In historical whaling terminology, a (or "cratch") could refer to a piece or portion of whale blubber or meat. After flensing (cutting up a whale), the blubber was cut into "horse pieces" or "cracks" — rectangular chunks small enough to fit into try-pots (large kettles for rendering oil).

A "crack" was a piece of whale blubber cut for rendering. "Whaledown" could be a variant of "whale down" (to strip a whale) or a proper noun.

However, "whaledown" is not a standard English word. The most likely intended phrase is or a mishearing of "whale down" + "crack" in the context of whale hunting or processing .
