I like the Hawaiian and the Hornet. Also, that daycruiser is pretty nice too. Looks real clean for its age.
X2. The Hawaiian has a 455 Olds not a 454 (Chevy as advertised). The Olds is fine, just mentioned it so you're aware. I would guess it is also a little newer than 1971.
The Kurtis is a good hull, full stringer, Southwind clone. But it is a small block. And has ugly interior.

The cruiser does look nice. It won't set any speed records, but looks nice and will have a lot of extra room compared to the others.
If it's claimed to be a running boat by the seller, don't buy it without driving it.
