i think the boats that have a big history is a good thing. if the hunters and cats where not around in abundance it would say something about them... ie they did not last long enough.
for bay work and the icw both hunters ( late 70 to early 80's ) and cats are great boats. i personaly love my 83 hunter 27, yes i would like bigger but i would want the same lay out and looks.
the old boats that are still in good shape are worth the money, as they can be had for little money.
things to watch for on hunters is compression post issues, on cats its the wood in the hull that the keel bolts go thru. they each have good and bad, you really need to look at each to see what you like about them
