Based on nearly-the-most-delta-iest-delta hull shape I've seen, I presume so. Wondered if it could be the original, though it's got a fixed keel now. And as you mention, rudder looks new. Not much to go on but the white gunnel seems right. The name's font is wrong but obviously that isn't definitive. Can't tell if the transom return is rounder than the original. Hell, I don't even know if that photo is the original.
