Proas shunt reversing stem and stern - there is one rudder in each. I believe their best configuration is with the cabin (weight) to windward and the sails in the mainhull. Search for "harry proa".

Proas may be self righting (the one in the picture is). Conceptually the proa is lighter than any other multihull configuration. Unfortunately, proas need fore and aft hull simetry for shunting. They would be the best multihull configuration choice if it wasn't for this detail.
