New England is the strong hold for the Nacra 6.0NA...not too far from you (at least not as far as for me!). The 18sx is rated slower than the regular 18 - even WITH the spinnaker on the SX! I had a Hobie 18 and it's a great boat but the 6.0 is king of handling crew weight and like everyone else said, $500 difference for a 7 year newer boat is a no brainer.
