Due to security concerns by Yemen's Houthi rebels the cruise ship, Silver Moon had to adjust the current voyage from January 6th to 16th, 2024. Originally set to sail from Aqaba, Jordan, to Muscat, Oman, the Silver Moon's itinerary took an unexpected turn. Citing safety concerns arising from Houthi rebel attacks on ships in the Red Sea, the cruise will end at the port of Piraeus (Athens), Greece, instead of Muscat, Oman.

Guests aboard the Silver Moon were informed of these changes on January 9, 2024. The altered journey included calling at Egyptian alternative ports, Sharm el-Sheik and Sokhna, before transiting the Suez Canal to disembark in Piraeus.

In response to the evolving situation Silversea further adjusted the Silver Moon's schedule. As the Bab al-Mandab Strait at the exit of the Red Sea remains unsafe, subsequent voyages departing from Muscat on January 16, 2024, and from Dubai on January 26, have been canceled. The ship, devoid of passengers to ensure crew safety, will sail around Africa into the Indian Ocean. Regular cruises are expected to resume on February 11, 2024, starting from Mumbai, India, with the Silver Moon voyages continuing in Asia until the end of May 2024.

The security situation at the exit from the Red Sea to the Indian Ocean poses an escalating risk to cruise ship schedules. Silversea Cruises, confronted with these challenges, implemented a comprehensive route change, altering the disembarkation port and canceling two upcoming trips for the Silver Moon.

Currently, cruise ships with guests are prohibited from passing through the perilous Bab al-Mandab Strait. Alternatives such as trips without passengers or circumnavigating Africa, though possible, demand extensive schedule adjustments and travel cancellations.
