Top Dive Sites

The Main Wreck

Description: The Main Wreck of the SS Thistlegorm provides a comprehensive look into the sunken ship. At a depth of around 30 meters, the structure is divided into several sections, each with unique features. The bow and stern sections are particularly impressive, with the latter housing the ship’s massive propeller and impressive anti-aircraft guns. The wreck spans around 128 meters in length, offering an extensive area for exploration.

Marine Species: The wreck is home to a vibrant array of marine life. Divers can encounter schools of batfish, snapper, and trevally patrolling the site. The external structures are adorned with soft corals, sponges, and anemones, which attract colorful reef species like butterflyfish, angelfish, and occasionally, the prowling lionfish.

Unique Encounters: One of the highlights of the Main Wreck dive is the chance to see the ship’s military relics, including motorcycles, trucks, and ammunition. These relics, covered in marine growth, add a haunting historical element to the dive. Divers might also find themselves in the company of curious barracudas and large groupers that frequent the wreck.

Photography: The expansive and well-preserved nature of the wreck provides excellent opportunities for both wide-angle shots and close-ups of historical artifacts. Capture the dramatic lighting as it streams through the openings of the ship, highlighting the juxtaposition of man-made relics and natural coral growth.

Suitability: Due to the depth and potential for strong currents, the Main Wreck is best suited for intermediate to advanced divers. Proper wreck diving training is recommended to safely navigate the interior sections.

The Holds

Description: The SS Thistlegorm’s holds are perhaps the most intriguing sections of the wreck. These cargo holds are packed with wartime supplies, including Bedford trucks, BSA motorcycles, aircraft parts, and even steam locomotives. Accessing these holds involves swimming through expansive, well-lit cargo bays, which are now bustling with marine life.

Marine Species: Inside the holds, divers can observe smaller species like glassfish, soldierfish, and damselfish taking refuge among the relics. The encrusted cargo creates habitats for a myriad of crustaceans, including crabs, lobsters, and the occasional rare nudibranch.

Unique Encounters: Exploring the holds offers the unique experience of diving through history. The sight of perfectly preserved motorcycles and artillery adds an almost museum-like quality to the dive, enhanced by the presence of colorful sea life that has made these artifacts their home.

Photography: The holds offer stunning opportunities for capturing images of the ship’s cargo, encrusted with marine life. Use a wide-angle lens to photograph the interior spaces and detailed shots of the individual relics. The play of light within the holds can create dramatic contrasts, enhancing the photographic composition.

Suitability: The confines of the holds require careful maneuvering. This site is best suited for advanced divers who have experience with wreck penetration and good buoyancy control skills. A dive torch is essential to illuminate the darker sections and to avoid disturbing silt.

The Stern Area

Description: The stern of the SS Thistlegorm is one of the most iconic sections of the wreck. This area features the ship’s massive propeller and two large anti-aircraft guns, which still stand as silent sentinels. Diving here combines an exploration of the ship’s defensive features with a chance to see large pelagic species that are often attracted to the site.

Marine Species: The stern area is frequented by schools of jacks and trevallies, as well as solitary barracudas. The structure itself supports a rich growth of hard and soft corals, attracting reef fish such as anthias and wrasses. It is not uncommon to spot large moray eels tucked away in the nooks and crannies.

Unique Encounters: One of the highlights of diving the stern is the chance to see the resident sea turtles, which are often found grazing on the corals or swimming gracefully around the wreck. The sheer size of the propeller and the guns adds a dramatic backdrop to these encounters.

Photography: The stern provides a wealth of photographic opportunities. The propeller makes for an excellent subject due to its size and the marine life that surrounds it. Photographers can capture dynamic wide-angle shots, highlighting the contrast between the mechanical structures and the thriving reef ecosystem.

Suitability: The stern area, with its depth and the potential for moderate currents, is best suited for intermediate to advanced divers. Good buoyancy control and situational awareness are necessary to safely explore the area and handle the potential for current shifts.

Considerations for Each Dive Site

Water Temperature: The water temperature around the SS Thistlegorm varies seasonally, ranging from 22°C (72°F) in the winter months to a warm 29°C (84°F) in the summer. A 5mm wetsuit is generally recommended for winter dives, while a 3mm wetsuit or even a shorty may be sufficient during summer. Ensuring adequate thermal protection is essential for comfort, especially during longer dives that involve extensive exploration of the wreck.

Visibility: Visibility at the SS Thistlegorm can vary but typically ranges between 15 to 30 meters (50 to 100 feet). The best visibility is often found during the spring and fall months, though the site’s underwater clarity can be influenced by weather conditions and seasonal plankton blooms. It’s advisable to check current visibility conditions with local dive operators before planning your dive.

Currents and Tides: Currents around the SS Thistlegorm can be strong and unpredictable, particularly in the early morning and late afternoon when tidal movements are most pronounced. These currents can make navigation and buoyancy control challenging, especially for inexperienced divers. It’s crucial to plan dives according to the tide schedules and to be prepared for drift diving conditions. Utilizing a reef hook can help stabilize your position while exploring the wreck.

Safety Tips:

  • Dive Planning: Always have a detailed dive plan, including depth limits, dive duration, and emergency procedures. Discuss the plan thoroughly with your dive buddy or group.
  • Equipment Checks: Ensure all diving equipment, particularly your buoyancy control device (BCD) and regulators, are in excellent working condition. Carry an extra dive torch for exploring darker sections of the wreck.
  • Dive Training: Due to the potential for penetration dives within the wreck, having specialized training in wreck diving is highly recommended. This includes understanding silt-out conditions and safe entry and exit techniques.
  • Monitoring Currents: Be acutely aware of the current conditions and be ready to adjust your dive plan accordingly. Deploying a surface marker buoy (SMB) is essential for safety and to signal your position to dive boats.
  • Mind Your Air Supply: Regularly monitor your air supply and depth. The captivating nature of the wreck can lead to extended dive times, so keep a close watch on your remaining air and no-decompression limits.
  • Buoyancy Control: Practice excellent buoyancy control, especially when navigating the interior sections of the wreck. Disturbing silt can reduce visibility to near-zero conditions.
  • Stay Close to Your Buddy: Maintain close proximity to your dive buddy and use clear communication signals, particularly in low-visibility or current-prone areas.

Regulations: Adhering to local regulations and conservation guidelines is crucial to preserve the historical and ecological integrity of the SS Thistlegorm:

  • No Touching or Collecting: Refrain from touching artifacts or disturbing marine life. Do not remove any items from the wreck, as this is both illegal and unethical.
  • Eco-Friendly Products: Use reef-safe sunscreen and personal care products to minimize the environmental impact on the wreck and surrounding marine ecosystem.
  • Proper Waste Disposal: Dispose of all waste responsibly and avoid discarding any trash into the ocean. Keep the dive sites clean and free from pollution.
  • Diving Certification Levels: Ensure you are diving within the limits of your certification and personal experience level. The complexity of the wreck demands respect and caution, especially for deep and penetration dives.
  • Respect Dive Site Rules: Follow all rules and guidelines provided by local dive operators and authorities. This includes using markers, respecting no-touch zones, and adhering to safe diving practices.
  • Environmentally Friendly Practices: Promote and engage in environmentally friendly diving practices. Maintain neutral buoyancy, avoid contact with the wreck’s fragile structures, and participate in conservation efforts.
