As a Div 10 racer in one of the named evil fleets I have provided a clarification to the 3rd paragraph IHCA letter:

Since this time some regattas have included open class racing, mostly in Michigan, Florida and a few other places on the east coast. The practice has allowed racing throughout the east, particularly in Divisions 8 and 10 to survive. In both divisions Hobie fleets were abandoned and sailors revived racing through open class racing. Contrary to the NAHCA’s criteria sailors took over the administration of their fleets. In some cases the new multi-hull associations composed of open class fleets are stronger than ever. There is a strong indication that this practice is starting to spread to other divisions as well, and in our self interests we feel strongly about stopping it.

Mike,
Hobie 16, Mystere 4.3, Inter 20
P.S. Hobie: I have a Hobie lifejacket still in the shrinkwrap. If you want it back, give me a call. You pay the shipping and you can have the H16 back too:-)
