Other Mfg's V-20's

[Steplift 72']

I've said that an old fishing buddy had a heavy waterlogged V-20 clone with an OMC sterndrive. It seldom ran because of the old sterndrive, he finally tore the floor out and found the foam level full of water. While looking on E-bay for boats I found a "Seabird" original advertisement from 1967. The boat was called a Seabird V-202 and it's not just close, it is the real deal with a Seabird name on the side. In fact I think it's the earliest version I've seen with the Wellcraft style, almost flat 3 piece windshield. I suppose the Formula 233 is still the most copied, but this might be close to the worlds most reproduced & copied boat if you add them all up. Alim, Glasspar, Seabird, Wellcraft, Chapparal, Cruise, Campagna (24' including a 3' fantail). Any other copies known?
