There is no traveller - just a single
attachment point on the hardtop for the mainsheet. The mainsheet attaches to the end of the boom, through a attachment block, through the boom, down to a block at the base of the mast
and to the organizer/clutch/winch. That would be the yellow line in the picture. The jib
is self-tacking and has the jib
sheet connected to a padeye on the cabin
top, through a block on the jib clew, through a block on the other side of the cabin
top and back to the organizer/clutch/winch.
