In larger boats these sails are not easily raised by man power. And unless they're attached to a rotating mast, they still suffer a significant loss of effective sail area. Mainsails do not come down or go up with any ease unless the boat is pointed into the wind. And this shortcoming is exacerbated in heavy weather . Considering just those characteristics above, we really do have to call into question the use of a mainsail at all.
Lets call it a marriage between a cutter and a ketch without the mainsail.
The original design was published in Yachting 1974 and in Multihulls 1975. Rudder magazine also made note of it in 1974. It didn't get built and neither did the rig. It went into hibernation. This necessitated that the mast be stepped aft in the cockpit area and canted forward approximately 10 degrees.
