Odyssey
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
The Odyssey is Roatan's big wreck, a ninety-meter island freighter sunk for divers in 2002 after a fire ended her working life. Scale is her personality: the hull runs longer than most divers' entire no-deco window at depth, so tours pick a zone — the towering stern castle one day, the cavernous forward holds the next. Silversides pour through companionways in season, barrel sponges have staked out the rails, and the superstructure's upper decks sit shallow enough for a comfortable mid-dive. Together with El Aguila down the road, she gives Roatan a legitimate two-wreck itinerary.
The moment you come for: One of the western Caribbean's larger intentional wrecks, hold and stern-castle tours, seasonal silversides.
Topography: A large freighter — roughly 90 m — scuttled in 2002 on sand at the base of the reef slope, largely intact and upright.
Entry: Moored site near Sandy Bay, often alternated with El Aguila.
Know before you splash
Hazards: Depth and genuine overhead spaces; the sheer size invites overstaying — watch gas and time.
Conservation: Marine-park artificial reef; interior spaces are for trained wreck divers with guides.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
