[quote=rehmbo]I'm far from an expert, but I think you can find some good info on the Hobie 18 FAQ page here: [url=http://www.hobiecat.com/forums/viewtopic.php?f=13&t=12780]http://www.hobiecat.com/forums/viewtopic.php?f=13&t=12780[/url]
Beam width is the same for both at 8ft. Sail area is 20sqft less on the SX but is much higher aspect ratio and is probably a "faster" sail. Picture on the FAQ page shows an SX with an optional spinnaker.
Informal racing against SE is up to the guys you're sailing with. However, I'm certain it wouldn't be allowed in a Hobie sanctioned event.[/quote]
