Ed,



The Mystere 5.0 is very similar to your N5.0. It's boardless but with symmetric hulls. The built in skeg in the hull is more well defined (like on some of the new boardless Hobies) in terms of the hull shape.



I believe that the Mystere 5.0 comes is an XL version also that includes a spinnaker set up. Never sailed one but have seen them around.
