Diving atLanding Craft-Sirotkin Reef (United States)
The foundation for the Landing Craft-Sirotkin Reef system originates from deliberate efforts spanning decades. Martin County's Artificial Reef Program, initiated in the 1970s by the "Reeftirees," actively secured and deployed various materials. These projects often utilized concrete debris from demolished structures, like the Evans Crary Bridge, and dedicated reef modules. Separately, the Georgia coast features a sunken landing craft, which, like the Sirotkin area's structured deployments, serves as a significant artificial habitat, attracting diverse aquatic life through human ingenuity.
Evening condition tracking at Landing Craft-Sirotkin Reef features an air temperature of 26.5°C. We have recorded wave heights measuring 0.3 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
Encompassing a diverse underwater topography, the Landing Craft-Sirotkin Reef system is largely formed by intentionally deployed artificial structures. Off the coast of Georgia, a sunken landing craft provides a distinct focal point, its deteriorating hull attracting a variety of marine life and offering nooks for exploration.
In Martin County, Florida, the Sirotkin permitted reef area features multiple artificial reefs. Among these are the Hailey Glasrud Reef, a steel vessel, and various concrete rubble reefs within the Donaldson site. Local programs also utilize concrete bridge pieces, such as pilings and deck span sections, creating a complex, rugged environment that contrasts sharply with the surrounding seabed.
Reefs in the Sirotkin area have been strategically placed to form dive trails, connecting distinct features like the Railroad Tie reef and the Tetrahedron Black reef. This deliberate placement enhances the diving experience, allowing for extended exploration of multiple structures during a single outing.
Across this combined system, depths typically range from shallower sections down to a maximum recreational depth of 30 m (100 ft). Many of the newer concrete reef modules were deployed between 16.7 and 18.3 m (55 and 60 ft), while other established Sirotkin reefs extend deeper to 21.3-24.4 m (70-80 ft).
Such an extensive network of artificial structures provides abundant shelter and surfaces for colonization, effectively transforming barren seafloors into vibrant underwater ecosystems suitable for both experienced divers and those seeking intermediate challenges.

Best Time to Dive
Determining the optimal time to visit the Landing Craft-Sirotkin Reef involves balancing diverse seasonal conditions. Summer months, particularly from May through September, generally offer the most favorable diving conditions. During this period, average air temperatures range comfortably from 26°C to 28.5°C (79-83°F), accompanied by minimal average rainfall, typically between 2.3 and 3.5 mm. Dive scores are consistently rated "Good," indicating stable weather and calmer seas. May, June, July, and August show high scores, with September remaining a strong contender before conditions shift. As autumn progresses, a noticeable contrast emerges; October is generally considered a poor month for diving, primarily due to increased wave heights averaging 1.6 m (5.2 ft) and higher average rainfall, around 6.33 mm. Winter and early spring months, from November to April, fall into the "Moderate" dive score category. Air temperatures during these cooler months range from 20.5°C to 24.5°C (69-76°F). While still diveable, divers should anticipate choppier conditions and larger swells, averaging 1.2 to 1.4 m (3.9-4.6 ft), making the summer window decidedly more appealing for predictable and comfortable excursions.

Dive Experience & Conditions
Divers exploring these artificial reef systems will encounter varying conditions depending on the specific structures and locations. Much of the dive experience unfolds in the shallower recreational range, though some sites extend to deeper sections. Visibility is generally mild, allowing divers to appreciate the intricate details of the wrecks and concrete modules. Currents are not consistently reported as strong, but conditions can fluctuate with local weather patterns. Surge can also be a factor, particularly in shallower areas or during stronger winds. Water temperatures exhibit a significant seasonal range. During summer, from May to September, expect comfortable water temperatures between 22.0 and 28°C (72-82°F). However, winter months see a substantial drop, with temperatures falling to 8-12°C (46-54°F). These cooler temperatures necessitate appropriate thermal protection. Given the maximum depth of 30 m (100 ft) for some landing craft sites and the rugged nature of the artificial reefs, an intermediate certification level is generally recommended to safely navigate the environment.
Dive Difficulty & Safety Guidelines
Approaching the Landing Craft-Sirotkin Reef requires adherence to standard diving safety protocols, particularly given the nature of artificial reef structures. While specific hazards are not consistently reported, divers should always be mindful of potential entanglement risks from fishing lines or loose debris commonly found on artificial structures. Proper buoyancy control is essential to avoid disturbing the fragile ecosystems and to prevent accidental contact with sharp edges on concrete or metal wreckage. The "Intermediate" difficulty rating for these sites suggests that a minimum of an Advanced Open Water certification, or equivalent experience in deeper artificial reef environments, is advisable. Always dive within your training and comfort limits. Planning dives carefully, considering the potential for mild visibility fluctuations and occasional surge, ensures a safer experience. Diving with a reliable buddy and carrying appropriate safety equipment, such as a dive knife and surface marker buoy, are prudent measures for these dynamic underwater landscapes.

Marine Life at Landing Craft-Sirotkin Reef
The rugged underwater landscape of the Landing Craft-Sirotkin Reef serves as a crucial habitat, attracting a diverse array of marine species to its artificial structures. Within the crevices and along the surfaces of the sunken landing craft and concrete modules, divers frequently observe various fish species seeking shelter and foraging opportunities. This artificial environment supports the growth of encrusting organisms, providing a food source and nursery grounds. Schools of baitfish often congregate around the structures, which in turn draws in larger predatory fish. Expect to see different types of reef fish, potentially including snapper, grouper, and various invertebrates adapting to these human-made habitats.
