GJOA is commonly thought to be a ROZINANTE, and at first glance it's difficult to tell the difference on the water.  However, GJOA is ROZINANTE's older, (not by much), larger (not by much) sister.  #96 has a balanced spade rudder and was designed for inboard power.  The mizzen mast sits on the aft deck with the tiller located under the deck (the rudder post is aft of the mizzen mast step).  These details can be seen on the construction plan under the SPECIFICATIONS image. Given the Sail Area/Displacement, Displacement to LWL and LWL to Beam ratios of the two boats it would appear that ROZINANTE should be a little quicker than GJOA.
