Hi, C. You have BAD information. There were no kids or adults from west of Michigan at the 2002 USSA Youth Cat Nationals so your kids could NOT have made a determination about the Mystere 4.3 from actual experience. I have sailed the Hobie 14, THAT is why I say it is hard to get excited about it. The Mystere 4.3 has main, jib, and spinnaker w/ snuffer that can be sailed w/ any combination of those sails and w/ one or two people competively. It has much more buoyancy than the H-14 and will cost less than a new H-14. The Mystere 4.3 has very responsive handling and will train kids from beginners to advanced, including the use of a spinnaker which is quickly becoming common on cats.
Now if you want to just get Hobie 14s for some reason, then knock yourself out but do not portray it as a decision reached after actually comparing the boats listed because that is just not the truth.
