More than 99% of freight is transported by sea. Both Moroni on Njazidja and Mutsamudu on Nzwani have artificial harbors. There is also a harbor at Fomboni, on Mwali. Despite extensive internationally financed programs to upgrade the harbors at Moroni and Mutsamudu, by the early 1990s only Mutsamudu was operational as a deepwater facility. Its harbor could accommodate vessels of up to eleven meters' draught. At Moroni, ocean-going vessels typically lie offshore and are loaded or unloaded by smaller craft, a costly and sometimes dangerous procedure. Most freight continues to be sent to Tanzania, Kenya, Reunion, or Madagascar for transshipment to the Comoros. Use of Comoran ports is further restricted by the threat of cyclones from December through March. The privately operated Comoran Navigation Company (Société Comorienne de Navigation) is based in Moroni, and provides services to Madagascar.
