Bimini

Before Departure

Ask the operator about certification, dive profile, group ratios, oxygen and first-aid kit, radio/communications, emergency procedures, up-to-date boat inspection, site shelter, current limits and reef or shark briefing. For a specialist hammerhead encounter, obtain the written protocol and any minimum certification and experience requirements. Do not infer that a shallow depth makes a big-animal trip suitable for a nervous first-time diver.

In the Water

Avoid wreck penetration, uncontrolled drift, touching corals or wildlife and competitive breath-hold dives. Watch the boat ladder and propeller area. Divers should maintain buoyancy and air reserve; snorkelers need flotation and active boat lookout as appropriate. Freedivers need a rescue-trained buddy in the water and no hyperventilation. Cancellation for wind or lightning is an expected safety decision.

After Diving and Before Flights

DAN suggests at least 12 hours before flying after a single no-decompression dive and 18 hours after multiple dives or multiple days, with more conservative intervals often appropriate. Technical or decompression diving requires different planning. If symptoms consistent with decompression illness occur, do not board an aircraft. Seek immediate local medical evaluation and contact DAN.

For life-threatening emergencies, call 911 or 919 in The Bahamas and request local medical response. The national emergency directory publishes Bahamas Hyperbaric Center contact numbers, but that does not verify Bimini-based treatment, chamber readiness, availability or transport times. DAN explicitly advises that a diver with suspected decompression illness should first be medically assessed, rather than bypass facilities for a named chamber. Confirm on-island clinical arrangements and possible medevac logistics with the dive operator and insurer prior to departure. For emergency diving-medicine advice, DAN lists +1 919 684 9111 at all hours. Do not assume regular ambulances, boats or flights will be available in heavy weather.

Sharks and Dolphins

The Bahamas National Trust describes sharks as legally protected in Bahamian waters. Treat all wild sharks, rays and dolphins as autonomous animals. Maintain a respectful separation, do not touch or chase them, and use an operator with documented wildlife procedures. Bimini Shark Lab research on great hammerhead return patterns and changing sightings reinforces why encounters should not be marketed as guaranteed.

Coral and Wreck Integrity

Keep fins and weights off reef, do not collect shells or living organisms, follow any site-specific fishing restrictions and avoid anchoring on coral where moorings are available. Do not remove objects from the Sapona or enter weak structural areas.

Proposed Reserve Versus Active Rules

Bimini Shark Lab describes the North Bimini Marine Reserve concept but says formal implementation had not occurred as of its cited account. The Bahamas Protected Areas Fund lists it in proposed expansions. This is not evidence that the area is open to unlimited activity; existing national fisheries, navigation and property rules still apply. Obtain updated legal boundaries and permission from the appropriate Bahamian authority before claiming a park closure, no-take designation or compulsory dive tag.
