Dive a living underwater archive of D-Day and Channel maritime history
Normandy combines cold water, strong tidal streams, variable visibility, offshore boat logistics, unstable wreck structure, and culturally sensitive sites. Use an established local operator, disclose experience honestly, follow the tide plan, and accept substitutions or cancellations. Carry appropriate thermal protection and surface-signaling equipment. Treat every wreck as an archaeological site and possible memorial. In an emergency, alert the boat immediately; at sea use VHF Channel 16 or call maritime emergency number 196, with 112, 15, and 18 available ashore. CROSS and SAMU should coordinate evacuation and the receiving medical facility.
For a suspected diving injury, give high-concentration oxygen when trained and equipped, protect the diver from cold, stop further diving, and contact the boat's emergency chain. At sea use VHF Channel 16 or 196; ashore use 112 or 15. CROSS Jobourg and SAMU can determine the appropriate hospital, helicopter or lifeboat response, and hyperbaric destination. Do not assume that the nearest local hospital has a chamber, and do not drive a symptomatic diver long distances without medical direction. Bring a concise dive profile, computer, gas details, medical history, and insurance information. DAN Europe can provide specialist diving-medicine assistance, but public emergency services should not be delayed.
Strong tidal streams
Normandy wreck dives are scheduled around slack water. A delayed entry, slow descent, missed line, or extended bottom time can put a team into building current. Follow the director's timing exactly.
Cold, low light, and variable visibility
Thermal stress and task loading can build quickly. Use appropriate exposure protection, lights, conservative gas reserves, and a simple navigation plan suited to current visibility.
Unstable structure and unexploded ordnance
Wrecks can collapse, entangle divers, and contain ammunition or explosive hazards. Do not penetrate, move objects, strike metal, or touch suspicious material. Report dangerous finds through CROSS Jobourg.
Boat traffic and long offshore recoveries
Carry a DSMB, remain with the planned ascent system, and surface where the boat expects you. Independent swimming near harbor approaches, moorings, and wreck boats is unsafe.
DRASSM's diver guidance is explicit: do not penetrate wrecks, remove artifacts, disturb fauna, or interfere with dangerous material. Corroded decks and bulkheads can fail without warning, while fishing line and sharp metal add entanglement and injury risk. Many D-Day sites are linked to fatalities and deserve memorial respect even when they are not formally marked as war graves. Photograph without staging or moving objects. Maintain neutral buoyancy over sediment and fragile growth, do not feed or handle animals, and secure gauges and alternate air sources. Report suspected explosive hazards to CROSS Jobourg and significant new damage or discoveries to DRASSM through the operator.
Do Not Do This
Avoid entering when strong tidal streams. Confirm local briefings before committing.
