Okay hear me out and this may sound like the ramblings of a lune but i just thought the following.

Surely a perfectly flat tight sail would more effectively convert wind energy into forward momentum rather than a full sail which would first have the wind hit it at a slight angle pushing the sail in that direction rather than perfectly straight forward.

I realise there are practicalities in operating a very high tension sheet but this lives purely in the hypothetical realm.

Does this make sense or have i been drinking drain cleaner again.

Sails don't really work like that. Sails are actually more like a wing. They create lift but pull sideways instead of lifting like airplane wings.

There are also crazy racing sailboats that use a ridged wing.
