COCOS ISLAND EMERGENCY EVACUATION PLAN: There is a new mandatory $30 charge for an “Emergency Evacuation Plan” that will be paid onboard the yacht. In the unlikely event that a diving accident or medical emergency occurs while 300+ miles from the mainland at Cocos Island, it is imperative that the injured party be transported to a medical care facility as quickly as possible. When medical evacuation is needed, this service (which is administered and operated by the Traveler Emergency Medical Services (Traveler EMS) subsidiary of Divers Alert Network utilizes pre-established and pre-authorized emergency evacuation protocols that have been created to facilitate the immediate dispatch of medical transport. Depending on the benefits under other policies held by the guest, their insurance carrier may or may not have logistics in place to deal specifically with Cocos Island – which could result in delayed response times for the medical evacuation and ultimate first responder care. This new program benefits every passenger aboard, not only the injured diver. Currently if the injured diver’s insurance plan fails to respond quickly enough with evacuation plans, the captain of the yacht would be obligated to terminate the cruise early and head back to port – thus impacting everyone’s travels. This new program minimizes this risk for all guests. DAN’s Traveler EMS “Emergency Evacuation Plan”only provides 1st responder care (if available) during transport and transport to a medical facility. It does NOT provide medical care. All divers visiting Cocos Island are required to have some form of diving accident insurance and are encouraged to purchase Trip Cancellation and Interruption Insurance as well. Your diving and travel insurance policy(s) provide you the financial protection for the actual medical care plus any further medical transport above and beyond returning you from the yacht to a local medical facility on the mainland.
