Interesting discussion re the 2-6 Heave. As an ex British matelot, I pulled hawsers and ropes to this many times. I agree that it would be impossible for 2 guys to pull in a heavy pounder alone.
Here's a thought ...
Toutes = ALL (all of you/all together)
Six = Six (ALL six of you)???
Haler = Haul (French nautical term for haul) (pronounced 'ale)
So ... Toutes Six Haler = All six together, heave.
