But not when using the "furling" option. If you have a furling sail
up it will be attached to the swivel and if you hoist a new sail
before lowering the old you will not be able to lower the swivel or
the old sail... There may be other justifications for dual slots
(twin headsails for trade wind sailing, redundancy, or racing sail
changes when the swivel (and therefore the furling) is not used) but
they aren't for changing sails when cruising.

Yes that is true of course. My boat came from a racing background and has
several Mylar foresails, all of which fit the grooves. This is all very well
but it needs two peole to handle sail changes as one has to man the
halliards while the other feeds the sail into the foil. I sail with just my
wife for crew so all those racing sails are in the basement at home and I
stick with a 130% dacron genny which is specially designed for the roller.
Even though we only cruise I do not like a slow boat and we hold our own
pretty well with most boats our own size so I am happy.
