Dive Site Overview
Sunk in 1985, the 220-foot steel-hulled freighter Proteus lies quietly within the Key Biscayne reef site, presenting a compelling narrative for divers. Once a ferry on the Great Lakes and later a Caribbean cargo vessel, its operational life ended in bankruptcy, leading to its eventual preparation and sinking as an artificial reef.
Resting at a maximum depth of 22-23 m (72-75 ft), with its top deck around 15 m (50 ft), the wreck provides substantial relief. This site is particularly well-suited for a second dive of the day due to its accessible depth. Historically, thousands of discarded license plates from an auto shop found their way into the vessel, a detail some divers still search for.
As an artificial reef, it has fostered a rich ecosystem, making it an excellent introduction to wreck diving in South Florida.
Best Time to Dive
For optimal visibility and comfortable conditions at Proteus, planning a dive between April and July is generally advisable. During these months, the dive scores are 'Moderate,' reflecting more favorable overall conditions. June and July specifically feature the lowest average wave heights, around 1.3-1.4 m (4.3-4.6 ft), alongside reduced wind speeds, typically 32-34 km/h (20-21 mph). Air temperatures during this period range from approximately 19-27°C (66-81°F), enhancing the surface experience. While rainfall remains relatively consistent throughout the year, the combination of calmer seas and lighter winds during these spring and early summer months often contributes to better underwater clarity compared to other seasons.

Dive Experience & Conditions
Exploring the Proteus wreck involves descending to its maximum depth of 22-23 m (72-75 ft), a range primarily suitable for advanced open water divers. With considerable relief, the wreck’s highest points rise significantly from the seabed, allowing for extended bottom times and easier access to its prominent features. Visibility around the wreck is frequently good, often extending to 15-20 m (50-65 ft), providing clear views of the structure and its marine inhabitants. This artificial reef structure, a sunken freighter, provides ample nooks and crannies for exploration, drawing a variety of fish and invertebrates. Currents here vary, depending on local weather patterns and tidal movements, so divers should always confirm conditions with local dive operators before entry. Surface conditions can range from calm to moderately choppy. Dive planning should account for these variable factors to ensure a safe and enjoyable experience.
Dive Difficulty & Safety Guidelines
Approaching the Proteus requires a commitment to responsible diving practices and appropriate training. While considered accessible for novice wreck divers to explore externally, any contemplation of internal exploration necessitates specialized PADI Wreck Diver certification and meticulous planning. Divers should always be mindful of their surroundings, respecting the integrity of the wreck and its delicate ecosystem. Carrying a dive computer and a surface marker buoy is recommended for safety and ascent management. Always dive with a buddy and conduct thorough pre-dive checks, especially given the boat access nature of this site.
