It serves as a submerged testament to historical events, drawing divers interested in underwater heritage.
Evening condition tracking at LT221 features an air temperature of 23.5°C. We have recorded wave heights measuring 0.1 m during this period. These figures outline the environmental parameters currently present.
Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Exploring the LT221 site reveals a pontoon barge resting on a wide, sandy bottom, a silent witness to its World War II past. This intriguing structure, while only a few meters high and predominantly flat, provides an exceptional foundation for local marine ecosystems.
Situated approximately a mile from the American tug boat it was once associated with, the wreck descends to a considerable 50 m (164 ft). Its maximum depth, coupled with its distinct squared profile and deep placement, makes the dive site exclusively fitting for technical divers. The primary draw for many isn't solely its historical significance but its vibrant role as a naturalistic habitat.
For those equipped and trained in technical diving, the wreck offers ample observation points for its diverse inhabitants, allowing a close look at marine life adapting to artificial structures. Journeying down to these depths requires careful planning and execution, rewarding experienced divers with a profound sense of exploration and a deeper appreciation for this submerged history.
Despite its relatively simple, flattened form, the site promises an engaging exploration, revealing how time and the ocean transform human artifacts into thriving underwater communities.

Best Time to Dive
For optimal diving conditions at the LT221, planning a trip during the warmer months, generally from June to August, is advisable. Consistently, these months show "Excellent" dive scores in system data. During this period, wave heights are typically lower, averaging around 0.4-0.5 m (1.3-1.6 ft), and wind speeds are milder, ranging from 15.85-18.52 km/h (9.8-11.5 mph). Rainfall is also minimal, with July reporting as little as 0.02 mm. While specific water temperatures are not consistently reported, warmer air temperatures, peaking at 28°C (82°F) in July, suggest more comfortable surface conditions and potentially warmer shallow water. Improved visibility often coincides with calmer sea states, enhancing the deep wreck experience. Outside these peak summer months, conditions still rate as "Good," but divers should anticipate slightly choppier seas and cooler surface temperatures.

Dive Experience & Conditions
Descent to the LT221 wreck is a journey into the deeper technical limits of diving, requiring careful preparation. As divers move through the water column, visibility can remain generally good, particularly during the calmer summer months, enhancing the view of the open water before reaching the bottom. Approaching the 50 m (164 ft) maximum depth, divers will observe the pontoon barge spread across the sandy bottom. Water temperatures in these deeper zones are not consistently reported but are typically cooler than surface waters, necessitating appropriate thermal protection. While specific current information is limited, conditions in the open sea can vary, meaning divers should be prepared for potential moderate flow and plan their dive accordingly. Navigating the wreck itself, given its relatively flat and spread-out nature, demands good buoyancy control to avoid disturbing the sandy seabed and to effectively explore its features.
Dive Difficulty & Safety Guidelines
Safety for a dive at LT221 starts with acknowledging its technical diving depth. A dive to 50 m (164 ft) requires advanced certifications, proper training in deep diving, and technical equipment suitable for extended bottom times and decompression. Divers must meticulously plan gas mixes and consumption, accounting for increased pressure and potential for narcosis at these depths. Maintaining excellent buoyancy control is crucial to avoid entanglement with wreck structure or disturbing fine sandy sediment, which could significantly reduce visibility. Always dive with a reliable buddy team and carry redundant systems. Prioritize continuous monitoring of your dive computer and gas supply, and be prepared for self-rescue or assisting others. Effective communication and adherence to established dive plans are fundamental for a safe and rewarding experience.
