Cordelia McMinn was 26 when she and her husband John left Hanalei, Kauai County, in spring 1976 intending to sail their 25-foot trimaran, the DRUM, to Washington State. The couple told family they planned to depart in May and were last seen boarding the vessel in Hanalei; they never arrived at their destination and were never heard from again.

The DRUM was a distinctive homemade brown trimaran with white hulls and gold trim, main sail number 188, a working jib, a Genoa jib, a multi-colored drifter sail, and Drum painted in green script on both outriggers. The boat carried an 8-foot plastic dinghy, a self-steering vane, and bore Hawaiian registry HA4674C on the main hull’s bow. The main cabin had two round portholes on the port side and oval windows fore and aft.

No trace of Cordelia, John, or the DRUM has been found despite investigations and comparisons with unidentified remains. The circumstances of their disappearance at sea remain unknown. If anyone knew the McMinns, saw the DRUM in Hanalei in spring 1976, or has information about that voyage, please come forward.
