I’m of the mind it’s a CD 30C/K as well . . . just with round portholes. I haven’t located a hull number yet – I can’t see anything on the transom/stern. There is an expired boat license number on the bow but when I look it up in the database nothing shows up. The guy I bought it off of had no idea what it was – I think he advertised it as an Alberg or something. Thanks for the info.
