Odyssey Adventures (MV Odyssey)

A 132-ft air-conditioned liveaboard for up to 16 guests running Saturday-to-Saturday seven-night trips from Weno with up to five dives a day, free nitrox and a technical-diving crew (trimix, CCR support). The operator lists the sites it commonly visits, from shallow Fujikawa Maru to deep San Francisco Maru, and says not all are visited each week.
