This interim was a transition period for the company, when the American vessels stopped operations at the Egyptian ports cause of June War. This pushed the company to shrink its services until the end of October war at the year 1973.
On 1974 the American lines took the decision to recall the Egyptian ports, thus the company resumed once again providing its services, indeed new contracts with other American lines like:
- Farrell lines Inc.
- American President Lines
The company built her own barges to lighten the vessels tonnage at the anchorage area before its berthing alongside the piers. Also, the company built tug boats specialized for the towages operations (To tow barges from vessels to piers and vise versa).
On 1976 the individual institution of Mahoney’s Co. has been transferred into “Mahoney Shipping and Marine Services”.
