Classic. And what is the "advantage" of "rigging in advantage"? (Small hint: it gives you an extra helping force on the load!)

Anyway, my terminology might be wrong, but the analysis is correct. I'm not saying it's one or the other -- just referring to the pictures as an explanation.

Regardless, my point was that w.r.t. the load on the lower pulley, the last loop over the top pulley in the luff doesn't add anything (really, it doesn't!). But I guess only understanding the physics and not knowing the terms makes means you can still go home feeling high and mighty about your sailor's license.
