Hi weltj and welcome to the forum. I owned a Siren while I was in University and they are a great little daysailor/occasional overnighter. As I
recall, the mainsheet system changed during production - the original ones had a
bridle arrangement (two fiddle blocks on each corner of the transom), while some later ones had a
single fiddle block on the
cockpit sole.
With respect to the rest of the
rigging - very simple, actually. There was a basic
furler on the forestay, two shrouds mounted well aft and, if I remember correctly, no backtstay. There are two (I believe external) halyards that cleat on the
mast (no winch), an
outhaul on the boom (again without a winch) and two pivoting cam
cleats for the
genoa sheets (some also had small tracks and fairleads). That's about it.
For raising and lowering the
mast, attach the foot of the mast to the mast base with a pin, attach the halyards losely, have someone on
deck to guide the mast side to side, attach a line to the end of the forestay and have someone pull it up into position and then insert a clevis pin in one of the slots (there is no turnbuckle on the forestay, as I
recall, but rather slotted plates).
