Milan Vucurevich Jr., 37, an experienced boatman and former U.S. Marine who worked as a builder and home designer on Kauai, vanished on June 3, 1984, while sailing an 18-foot catamaran in Hanalei Bay with two friends, Mary Huston and Jim Chouinard. The three left for a short afternoon sail and never returned; the outing appeared casual, with Vucurevich leaving his wallet behind and Chouinard leaving his dog on the beach. An eight-day search by Coast Guard, Navy and civilian volunteers covered thousands of square miles but found no trace of the occupants or the catamaran.

Vucurevich’s parents held out hope he had survived, and his father, a retired U.S. Army colonel, suggested Navy missile tests that day—reportedly involving white styrofoam targets similar in size and shape to the catamaran—might be connected. The Navy denied involvement; the family pointed to a separate 1988 Navy missile accident near Kauai that caused a fatality as lending weight to their suspicion. The disappearance remains unsolved and unexplained.

Did anyone on Kauai at the time recall Navy activity off Hanalei Bay that afternoon, or remember sightings of the catamaran before it disappeared?
