Angel, who is married and lives in Durban, will take command of the Safmarine Ngami - a 2,474 teu containership deployed on the South Africa/North America (AMEX) trade - in mid-October 2008.
Earlier this year, she also became the first female officer to take delivery of a new Safmarine containership - the very ship of which she will now be at the helm.
Commenting on her appointment, Safmarine CEO Ivan Heesom-Green said: "As a seafaring Safmariner, Louise has demonstrated her ability and commitment and her appointment to Master is an excellent achievement - and one of great pride to all Safmariners."
