Jack,

Whereabouts are you located? There is an active Isotope fleet in the Raleigh NC area. If you are somewhere nearby and would like a firsthand look or a ride, drop me a line.

The Isotope actually predates the Hobie 16, but it is significantly faster - about the speed of a Hobie 17 or 18. It's also easier to sail, having symmetric hulls, centerboards, and a balanced rig that give it a nearly neutral helm. The Isotope is lighter, and can be rigged, sailed, and righted solo. It's one of the few cats that can sail inside 45 degrees to the true wind, and it moves in very little wind. I can fly a hull in a 5kt breeze.

It's a fun boat, but more of a performance cat than a beach cat. The Hobie 16 is built like a tank, and you can sail it up onto the sand without much damage. The Hobie is also easier to control in heavy air or big waves.

Regards,
Eric
