Itīs little trickier in downwind because its dubble spreader but is it good?
I don't see it having any disadvantages but then I don't see any advatages to it either. Not having a backstay does not seem to offer anything I can think of. With a carbon Fiber rig you don't need any shrouds. Our rig can stand without any spreaders but they added them so they would make the boat look right.
It all comes down to structural design. For the types of loads these boats take the design is perfectly fine. Hunter
has been doing it for many years.
