Article 1 – General

The right to navigate the Canal is granted to all ships, of whatever Nationality, under the condition that they comply with the present regulations. The Company reserves to itself the right to refuse the passage or towing of a ship in such situation where it considers a ship dangerous to the safety of Shipping in the Canal, or judges that such a ship would create irregularities during the passage of other ships, or because the Shipping Company owes the Company dues from passage, towing or pilotage charges.

One day a week, from 06:00 to 20:00 hours, the Canal is closed to shipping for maintenance purpose. This day of the week, which remains the same for considerable spaces of time, is laid down by the Company.

Article 2 – Draughts

The maximum draught of ships negotiating the Canal, in relation to their width, is defined as below, assuming normal water level and normal weather conditions.

 Width  Maximum Draught
 16.00 metres to 16.50metres  6.20 metres
 15.50 metres to 16.00metres  6.40 metres
 15.00 metres to 15.50metres  6.60 metres
 14.50 metres to 15.00metres  6.80 metres
 14.00 metres to 14.50metres  7.00 metres

The maximum draught for boats of less than 14.00 metres width is 7.20 metres. The maximum width must not anyhow exceed 18.30 metres (60 feet).

Special instances will be examined by the Master and the Canal Service in collaboration.

Article 3 – Speeds
The speed of a ship navigating the Canal must not exceed 6 knots (Nautical miles per hour). Upon entering and leaving the Canal, however, speed must be reduced to the minimum to avert damage to ships anchored alongside the piers at Isthmia and Poseidonia.
Article 4 – Towing

1) Towing is compulsory:
a) For sailing boats without a propulsive engine or with an engine of  inadequate capacity.
b) For ships of 800 Net Registered tonnage and over.
c) For ships of less than 800 Net Registered tonnage, in cases where the Service deems a passage without towing insecure, on the strength  of definite evidence.
d) For ships carrying explosives, inflammable and dangerous cargoes in general, as well as for empty Oil tankers.
2) The Canal Service is obliged to furnish a tug to ships of less than 800 Net Registered tonnage, if so requested by the Master.
3) Towing operations are performed by the tugs provided by the Canal for that purpose.
4) While negotiating the Canal, the ships engine must be kept running, granted that the chief function of the tug is to keep the ship on the canal’s axis.
5) The ship must provide the cables and hawsers required for towing with her engines idle.
