Dakar Peninsula

Before Boarding

• Confirm the exact named site, real maximum depth, certification and recent-dive requirements, planned gas, exposure time and expected current. Rebrief if the boat changes site.
• Ask the crew to demonstrate working oxygen, VHF/phone, crew-led surface search, boat pickup, recall and emergency notification procedures. Nautilus describes oxygen and communication equipment; do not infer current operational checks from this claim alone.
• Treat Ngor as a documented water-quality decision, not simply a sheltered training spot: Surfrider monitoring reported repeated contamination. Ask for recent tests for the precise entry area and dates; consider postponement after rainfall.
• Review local sea state, currents, surge, dive-computer/decompression limits and diver-to-guide ratio. Use a buddy, check equipment and carry a visible SMB on boat dives when instructed.

Depth and Overhead

Tacoma, at a reported 13 m, may suit a different experience level than Charbonnier and Titane at roughly 34 m. Technical/overhead penetration and planned decompression must never be treated as an automatic extension of a recreational wreck tour. The operator must demonstrate adequate equipment, gas reserves, specialized instruction, rescue capability and an evacuation plan. Do not enter wreck interiors, remove artifacts or use a technical site merely because it is marketed as available.

Parks and Surface-water Activities

The Madeleine park regulation transcription marks underwater activities prohibited or specially restricted. Obtain written boundary-specific authorization from the competent authority if any site is near its limits. For breath-hold activities, never dive alone or deliberately hyperventilate; confirm dedicated safety supervision rather than relying on general scuba boat presence. For snorkeling, ability to swim and direct surface supervision matter even in shallow water.

For any serious dive injury, stop diving, call Senegal emergency services (ambulance 15), give emergency oxygen if trained and equipped, and seek immediate professional medical assessment. Do not delay transport to diagnose decompression illness yourself. Divers Alert Network can advise and coordinate but is not a substitute for local ambulance response.

Recompression and evacuation remain an explicit verification gap. A currently functioning chamber in Dakar with a confirmed acceptance pathway was not independently established. Before deep, overhead or decompression dives, require the operator to identify its receiving hospital, emergency contact, oxygen provision, anticipated transport and any cross-border/air evacuation arrangement in writing. Confirm medical coverage and exclusions with your insurer; DAN explains why public chamber availability listings cannot replace an emergency plan.

Dakar is also a malaria-risk travel destination. Obtain an individualized pretravel assessment for yellow fever certificate conditions, malaria prevention and routine immunizations using the CDC Senegal advice. This is general planning advice, not medical clearance.

The Iles de la Madeleine are a national park for volcanic-island and marine biodiversity. Under the published restriction summary, harvest, wildlife disturbance, anchoring and underwater activity face substantial restrictions, while guided boat visits have specific rules. Current applicability and any legal exception must be established directly with park administration; a tourism itinerary is not a permit.

Keep distance from turtles and other fauna, do not touch coral, feed animals, take shells, collect wreck objects or use artificial lures. Secure fins and buoyancy so you never stand on reefs or stir sediment. Follow local Lebou coastal-community instructions and respect fishers and harbor operations. Help operators reduce litter without assuming any volunteer cleanup permits access to protected zones.

Surfrider Foundation Senegal has documented bacterial water-quality problems at Ngor and other Dakar bathing sites. Cleaner water is a measurable conservation and public-health issue, not a marketing descriptor: request current results rather than relying on photographs or wildlife presence.
