I'm pretty sure they have done the math before start marketing it like this.

There's also a system called SKYSAIL that attaches a giant tethered kite to a cargo ship, the kite goes high to get the faster winds. IIRC it's fuel advantage is better than 30% too.

There's various videos of it on youtube eg:

Using both together, perhaps you could never use fuel again (maybe only when near to ports, for safety.)

Jacques-Yves Cousteau was a Great man.

look for "Alcyone dans le port de Concarneau" about real using of such sails.

Should of watched it a bit longer they explain your exact sentiments

crosswinds would be a hell of a ride at that size o.o;
