That's it! I think the Planecat is the Richard Roque design -- it was a 16-footer, wasn't it? I I couldn't think of the name earlier. And Randy Smyth won the Worrell 1000 on the bigger Roque design back in the 1980's, just edging out Roy Seaman on the Nacra 6.0, which Seaman designed for the Worrell. If this is wrong, let me know. I got this info from Rick. Randy expressed his opinion at the time about the Roque design vis-a-vis the Nacra 6.0, but I am not going to repeat it, because I don't want to misstate somebody else's opinions.
