Two genoas on a single forestay or single furler:

Done a lot by tradewind sailors.
Most furler foils have two slots.
You can load two genoas, one into each foil slot.
One sail is held out by a whisker pole.
Usually only one sheet is fastened to a single clew.
If you need to go 'up weather' the 'lazy' genoa will just sit there
inside the one thats full.
When furling BOTH sails are rolled.
This arrangement is typically for dead-downwind sailing .... poor
tactic for 'any' sailing because it make for a 'rolly' boat.

The solent rig - two furlers on the centerline at the stem - is the
'modern' method.

Better to use a spinnaker and 'tack' downwind and take advantage of
higher apparent wind across the sails.

Furling TWO head sails? Interesting. inelegant but interesting.

I don't remember seeing the original, but it can be done with two
forestays, two wire-luff headsails on special tacks, or a combination of
the two.

Personally, I won't put an upwind sail on a wire luff again.

Two headsails at once can be handy, as can be a small and large one that
can be used independently (think cutter rigs).
