Algol dive overview: why this New Jersey wreck captivates experienced divers
The Algol dive off Point Pleasant Beach in New Jersey is one of the most characterful wreck experiences on the US east coast. This former US Navy attack cargo ship, USS Algol (AKA‑54), now rests as an artificial reef, offering a compelling mix of history, structure, and marine life for serious wreck enthusiasts. The Algol wreck lies at a wreck depth of around 30 meters (100 feet) on a sandy bottom, so this is a multi level profile that rewards careful planning, solid buoyancy control, and disciplined gas management.
The vessel, known officially as USS Algol, was intentionally sunk on 18 November 1991 to create an artificial reef, and today the USS Algol is a benchmark wreck dive for the region. According to NJDEP Artificial Reef Program summaries, the ship is approximately 459 feet (140 meters) long with a full‑load displacement of about 13,900 tons, and NOAA charts show the hull resting in roughly 145 feet of water with the superstructure rising shallower. When divers talk about a great dive in New Jersey, the Algol—often described as one of the most accessible deep wrecks—usually tops the list, especially for those who enjoy exploring large cargo holds and towering superstructure.
This Algol dive is reached by boat from Point Pleasant, with most charters departing from marinas near Shark River and Point Pleasant Beach. The wreck sits offshore from the Jersey shoreline at approximately 40°05.0′N, 73°59.0′W, a position documented on NJDEP reef charts and NOAA navigation maps. The site is exposed enough that swell and current can be significant, so dives are generally recommended for intermediate to advanced scuba divers. Because the Algol wreck is a designated artificial reef within the New Jersey Department of Environmental Protection (NJDEP) reef program, it has become a magnet for marine life, with mussels, fish, and encrusting invertebrates transforming the steel ship into a living ridge of color on the otherwise flat sand bottom.
History of USS Algol and how a cargo ship became an artificial reef icon
The story behind the Algol dive begins with the ship’s service as a World War II era attack cargo vessel built in Oakland, USA. What is the USS Algol? A World War II–era attack cargo ship commissioned in 1943, which saw service in the Pacific theater before later Cold War deployments and was finally sunk in 1991 as an artificial reef. NJDEP reef documentation and US Navy records note that after decades of duty, USS Algol was retired, transferred to the Maritime Administration reserve fleet, and ultimately selected by the NJDEP Artificial Reef Program for reefing—a decision that turned a working cargo ship into one of New Jersey’s most important artificial reef projects.
Before the sinking, engineers and divers prepared the USS Algol carefully, opening cargo holds, removing loose wiring and entanglement hazards, and ensuring the superstructure would settle safely on the sand. This preparation created a wreck depth profile that is challenging yet manageable, with the main deck shallower than the seabed and plenty of multi level options for staged ascents. NOAA chart soundings and diver reports confirm that the hull rests deeper than the bridge and upper decks, which allows teams to plan progressive depth exposure. The result is a wreck dive that balances safety and adventure, allowing divers to explore the bow, stern, and midships areas without excessive penetration while still experiencing the feel of a genuine working cargo ship.
Compared with other Atlantic wrecks such as the Norwegian tanker Stolt Dagali or the ghost fleets of the Pacific, the Algol wreck stands out for its deliberate transformation into an artificial reef documented in NJDEP reef program reports and NOAA regional charts. For readers interested in broader wreck history, the detailed guide to Truk Lagoon’s ghost fleet offers a powerful contrast between war losses and planned reef projects. On the Algol dive, you see how a ship once designed for cargo and troops now supports marine life and advanced wreck training, turning industrial steel into a thriving reef habitat.
Layout of the Algol wreck: bow, main deck, and superstructure highlights
Understanding the layout of the Algol wreck is essential before you dive Algol, because the ship’s size and complexity can feel overwhelming on a first visit. The bow section rises dramatically from the sand, giving divers an immediate sense of the ship’s displacement tons and the scale of this former cargo workhorse. From the bow, you can follow the hull line back along the ridge of the vessel, passing winches, bollards, and access points into the cargo holds that once handled wartime supplies and vehicles.
The main deck of the USS Algol forms the backbone of most standard dives, with the superstructure towering above and providing clear reference points even in moderate visibility. At this wreck depth, the bridge area and upper decks are often the first stop for photographers, who appreciate the play of light around railings and ladders on a bright Jersey day. Below, the cargo holds open into cavernous spaces where beams of light cut through the water, but these areas demand disciplined scuba skills, redundant lighting, and conservative penetration limits.
Charter captains with long experience on the New Jersey wreck circuit often brief the Algol dive as a multi level tour starting at the superstructure and finishing near the sand. One skipper described it simply: “Treat the Algol like a small steel city—pick one neighborhood per dive and really see it.” Typical briefings emphasize following the mooring line to the main deck, noting the orientation of the bow and stern, and using prominent features such as kingposts or mast stumps as navigation landmarks. Some operators combine the Algol wreck with other New Jersey sites such as the Stolt Dagali to create a full day of advanced dives.

Dive planning for the Algol: conditions, profiles, and safety considerations
Planning an Algol dive begins with recognizing that this is not a shallow reef but a serious wreck with a maximum depth of about 30 meters. The wreck depth places most of the main deck and superstructure in the mid twenties, which suits advanced open water or equivalent certifications with appropriate experience. Because the Algol wreck lies offshore from Point Pleasant Beach, conditions can change quickly, and divers should always check marine forecasts, swell models, and NOAA weather updates before committing to a trip.
Most Algol dives are conducted from a charter boat, with operators departing from marinas near Shark River and Point Pleasant Beach along the Jersey coast. These boats typically require proof of recent wreck dive experience and may ask for advanced or deep specialties, reflecting the multi level nature of the site and the potential for current. Standard guidance for the Algol dive includes booking in advance, bringing suitable scuba gear for cooler Atlantic water, and carrying a reel, cutting tool, and surface marker buoy for controlled ascents and drift pickups if needed.
Because the ship rests on sand, visibility can drop quickly if fins disturb the bottom near the bow or stern, so precise trim and careful frog kicks are essential. Many divers plan a first great dive focusing on the exterior, tracing the ridge of the hull and exploring the main deck, then reserve later dives for limited forays into cargo holds or sheltered areas of the superstructure. Charter briefings commonly stress staying on the mooring line during descent and ascent, monitoring no‑decompression limits or planned stops, and agreeing on a lost‑buddy procedure before entering the water. For those building a broader wreck diving itinerary, resources such as the elegant guide to snorkeling in the Sea of Cortez can help balance intense wreck days with more relaxed marine travel experiences elsewhere.
Marine life and artificial reef ecology on the Algol
The Algol dive is as much about ecology as it is about steel, because the USS Algol now functions as a thriving artificial reef on an otherwise featureless sand plain. Over time, the hull, bow, and superstructure have become encrusted with mussels, sponges, bryozoans, and other invertebrates that attract schooling fish and occasional larger visitors. What marine life can be seen at the USS Algol site? Various species including mussels, scallops, sea stars, black sea bass, tautog, and other temperate Atlantic fish common to NJDEP reef structures.
This artificial reef effect transforms the Algol wreck into a vertical ridge of habitat that rises from the sand and concentrates life in the water column. On some dives, you may see baitfish swirling around the main deck while predators patrol the edges, creating dynamic scenes for underwater photography. Although the site is not primarily known as a shark hotspot, the broader Jersey coast does see seasonal shark movements documented in regional surveys, and divers should always treat any shark encounter with respect and composure.
From an environmental perspective, the Algol—aka a planned reef—demonstrates how retired cargo ships can extend their service life by supporting marine ecosystems. The displacement tons of steel that once carried cargo now provide shelter and feeding grounds, enhancing biodiversity in this offshore location according to artificial reef monitoring reports. For marine travel enthusiasts, combining an Algol dive with visits to other artificial reef projects along the Atlantic seaboard offers a nuanced view of how wrecks, reefs, and responsible scuba tourism intersect.
Choosing operators, logistics from Point Pleasant, and pairing the Algol with other wreck dives
Access to the Algol dive is typically arranged through specialized wreck dive charters operating from Point Pleasant and nearby Shark River in New Jersey. These operators know the location intimately, from the best mooring points on the bow or stern to how swell wraps around the superstructure on different tides. Many charters schedule two dives on the Algol wreck in a single day, allowing divers to explore both the main deck and deeper sections near the sand while maintaining conservative no‑decompression or planned decompression limits.
Some boats build itineraries that combine the USS Algol with neighboring wrecks like the Stolt Dagali for a varied multi level day. This approach lets divers compare different wreck depth profiles, hull shapes, and cargo configurations while staying within a manageable travel radius from Point Pleasant Beach. For those traveling from farther afield, pairing a New Jersey wreck itinerary with other US coastal hubs such as Charleston or even West Coast ports like Oakland, USA, can create a rich, ship‑focused marine travel route that connects construction yards, naval history, and modern reef projects.
When selecting an operator, look for clear safety protocols, detailed briefings on the Algol dive, and crew who can explain features such as cargo holds, displacement tons, and historical context. Many New Jersey boats outline specific requirements such as redundant air sources for deeper wrecks, audible signaling devices, and surface marker buoys for every buddy team. Some charters collaborate with regional training centers to offer guided dives and advanced wreck courses on the Algol wreck, which is ideal if you want structured progression. Whether you are planning a single great dive on the USS Algol or a week of intensive wreck dives, thoughtful logistics and reputable partners will shape your overall experience more than any individual ridge, rail, or hatch on the ship itself.
