Course Change on the Atlantic: AIDAmar in a Medical Race Against Time

For the guests aboard AIDAmar, the great crossing of the Atlantic began differently than planned. After departing Basseterre (St. Kitts and Nevis) on the evening of December 8, 2025, the Sphinx-class ship was supposed to set a relaxed course for Tenerife. However, right in the middle of the so-called "Transition Zone"—the shift from the Caribbean archipelago to the open ocean—an incident occurred that forced the crew to act swiftly.

The "Point of Decision" On December 9, the ship was already on the open sea, heading strictly east at around 18 knots, when a medical emergency was reported on board. In such moments, precise protocols are activated on the bridge and in the onboard hospital on Deck 3. Since AIDAmar had been underway for less than 24 hours, the ship's command faced a crucial choice: continue and hope for aerial assistance, or turn back?

Since a helicopter evacuation over extreme long distances (well over 200 nautical miles) carries high risks and is heavily weather-dependent, the captain opted for the safest course of action for the patient: a "Return-to-Port" maneuver. The ship turned around and headed back toward the medical infrastructure of the Caribbean.

A Logistical Feat AIS (Automatic Identification System) data confirms that AIDAmar altered its course and reached positions near the islands of St. Kitts and Nevis again in the early morning of December 10. It is likely that the patient was handed over to shore-based rescue forces via boat transfer here—a common practice when the ship can navigate close enough to the coast.

Such a maneuver is no small matter nautically. It involves more than just a course change to starboard or port; it represents a massive intervention in the schedule. Approximately 24 hours of operational time were lost due to the return journey and the transfer.

Full Steam Ahead to Tenerife Now, the nautical department has to push the limits. To reach the scheduled call in Santa Cruz de Tenerife on time on December 15, AIDAmar must mobilize its reserves. Instead of a leisurely cruising speed, the ship is now expected to plow through the Atlantic at over 20 knots. While technically no problem for the diesel-electric propulsion system, this drastically increases fuel consumption.

For the passengers on board, this is an interruption of their routine, but also a reassuring sign: the rescue chain works reliably even far from home. As AIDAmar now rushes towards the Canaries at high speed, guests remain with the comforting knowledge that on board, a human life always takes precedence over the schedule.
