Patriot take a look at www.theclassicboathouse.com Theres a great set of galleries over there for just about any type of boat . I would say it looks 60's vintage to me but it is possible the owner registered it as a homebuilt in the mid 80's .
I'm going to check it out in the morning.The owner said it's always been covered and has NO rot(we'll see!)and comes with a bimini top(NIB i believe).If all is well,i'm going to offer $200-.I just wish i could find more Crosby info!
I havent dug up much on them myself and it is possible its newer as he says but it sure looks alot like a 60's era boat and I have 2 of them myself ( not Crosby's ) just 60's boats.
