Spice Islander I Ferry Sank Off Zanzibar in 2011
Spice Islander I was a small Ro-Ro ferry that sank off Zanzibar on 10 September 2011, resulting in one of the deadliest maritime disasters in the Indian Ocean. Built in Greece in 1967 and registered under several names and owners over four decades, the 836-tonne vessel was carrying far more passengers than her approved capacity when she went down between Zanzibar and Pemba Island.
The Vessel and Her Early Years
Spice Islander I was constructed in Greece in 1967 under the name Marianna. She measured 60 metres in length with a beam of 11.40 metres, making her a modest-sized passenger and vehicle ferry. Two Poyaud diesel engines, each producing 1,560 horsepower, powered the vessel. Her official capacity was 45 crew members and 654 passengers, though these figures would prove tragically inadequate on her final voyage.
Over her working life, the ship changed hands several times. She was sold to Theologos P. Naftiliaki of Piraeus, Greece, then in 1988 transferred to Apostolos Shipping and renamed Apostolos P. By 2005, she was registered to Hellenic Seaways and operated on the route between Piraeus and the Greek islands of Aegina and Agistri. In 2007, she was sold to Makame Hasnuu of Zanzibar, Tanzania, and renamed Spice Islander I for service in East African waters.
Engine Trouble and Rescue at Sea
In September 2007, Spice Islander I encountered serious difficulties while sailing from Oman to Tanzania. Contaminated fuel caused her engines to fail off the coast of Somalia. After the alarm was raised via Kenya, the United States Navy responded. USS Stout from Combined Task Force 150 reached the vessel and provided 7,800 gallons of fuel along with food and water for the ten crew members aboard. USS James E. Williams also responded to assist. Once her engines were restarted, the ship resumed her passage to Tanzania without passengers on board.
The Sinking of Spice Islander I
On the evening of 9 September 2011, Spice Islander I departed from Unguja bound for Pemba Island. She was reported to be carrying more than 800 passengers, far exceeding her licensed capacity of 654. Around 01.00 local time on 10 September, the vessel sank in the waters between Zanzibar and Pemba.
Of those aboard, 620 people were rescued. Only 240 bodies were recovered from the sea. Initial estimates placed the death toll at 2,976, but this figure was revised downward to 1,573 in January 2012 following a more thorough investigation. Many victims were never recovered, making the final casualty count uncertain.
Understanding Ro-Ro Ferries and Stability
A Ro-Ro ferry is a vessel designed to carry wheeled cargo and vehicles that drive on and off the ship via ramps. This design, while efficient for loading, creates stability challenges because the cargo deck is open and vehicles can shift during rough seas or if the ship lists to one side. Capacity refers to the maximum number of passengers and crew a vessel is certified to carry safely, based on lifeboat availability, deck space and stability calculations. GRT, or Gross Register Tonnage, is a measure of a ship’s total enclosed volume rather than weight. Beam is the width of a vessel at its widest point and affects how stable the ship is in rough water.
