I purchased one of the first Tasars sold in the U.S. and raced it for many years (rig designed primarily by Frank Bethwaite) and it has a rotating mast, full battened mainsail, and roller furling jib. This made it easier to sail the similarly rigged Hobie 18 that I bought new in 1980. The main difference being that it was much larger and heavier and rigid. I cannot think of any reason that any dinghy cannot use the same type of rig proven very effective by the Tasar.
