with natural fiber lines.
The mate threatened anyone who tied a locking hitch with a belaying pin.
Full turn around to start, two or three figure eights, depending, then another turn around the base to finish.
If you put a locking hitch in natural fiber and it got wet, you had the devil of a job to undo it.
If you put a locking hitch over too few turns for the load, you'll not get it undone or, if you do succeed, the line will burn your hand if it runs out under load.
With enough wraps, you can surge a highly loaded line off the cleat and also hold it.
I really appreciated the instruction when I started working on big boats.

Now . . . with the power cords . . . if you wrap enough turns around the cleat, can you grill a burger on the cleat by induction?
