Hilma Hooker

Overview: The 1984 Smuggler’s Shipwreck

The Hilma Hooker is a 72-metre (236-foot) Dutch cargo freighter that has become one of the Caribbean’s most iconic wreck dives.

Detained by Bonaire port authorities in 1984 after 25,000 pounds of marijuana were discovered behind a false bulkhead, the ship began taking on water while moored offshore and sank on 12 September 1984. She lies on her starboard side in a sand channel between two pristine coral reefs at a maximum depth of 30 metres (100 feet), with the upper hull at 18 metres (60 feet).

Detailed Dive Route

• Shore Entry: Park by the roadside marker and enter over the coral rubble beach. Surface swim 70 metres to the yellow mooring buoy.
• Descent to the Hull (18m): The massive steel hull comes into view through 30m+ Caribbean visibility, covered in orange tube sponges and brain corals.
• The Propeller & Sand Channel (28m–30m): Descend to the stern to inspect the colossal bronze propeller resting in the sand at 30m. Giant tarpons (up to 2m long) cruise along the keel.
• The Cargo Holds (20m–24m): Open cargo holds allow safe ambient-light swim-throughs for certified Advanced divers.
• Inner Reef Return (12m–5m): Finish the dive along the vibrant shallow reef crest of Angel City for your 5m safety stop.

Certification & Safety

• Certification: Advanced Open Water (30m) required for the propeller and lower hull; Open Water (18m) can view the upper port hull.

Technical Dive Profile & Navigation

1. Entry & Descent Mechanics

• Descent Method: Careful shore walk-in over reef platform or steps, kicking out to the descent buoy before dropping to prevent surface drift.
• Ear Equalization: Equalize continuously every 1 metre during the descent phase to prevent sinus or middle-ear barotrauma.
• Compass Heading & Navigation: Set a primary heading toward the main reef structure. Maintain buddy contact within 2 metres throughout the descent.

2. Deep Section & Gas Management (14m to 30m)

• NDL Discipline: At depths of 30m, your No-Decompression Limit ticks down rapidly. Monitor your dive computer continuously.
• The Craig Rule: Divers certified to Open Water level (18m maximum) must stay on the upper reef shelf and never follow advanced divers down past 18m.
• Turnaround Gas: Signal your buddy and start your ascent when the first diver reaches 110 bar (or one-third of usable cylinder capacity).

3. Ascent & 5m Safety Stop

• Ascent Rate: Ascend along the reef wall at a controlled rate not exceeding 9 metres per minute.
• Mandatory Safety Stop: Complete a strict 3-to-5-minute safety stop at 5 metres (15 feet) before deploying an SMB and surfacing with a 360-degree overhead scan.
