Port Draft & Vessel Restriction Database
Indicative maximum permissible arrival/sailing draft, LOA, beam and DWT for major bulk terminals, plus a quick vessel suitability check. Always reconfirm with the local agent and current port circular before fixing.
Tidal sailing windows only; convoy departures on the high tide. Pilotage compulsory.

Overview & methodology
Numerical Example: Vessel Suitability Check
The vessel can sail with a 0.3m under-keel clearance (UKC) margin at this port.

Frequently asked questions
How do I check if a vessel can call at a port?
Compare the vessel's LOA, beam and arrival draft against the berth's maximum permissible values, keep the required under-keel clearance, and add tidal window where the port is tide-restricted. Air draft under loading gear and cranes also has to be checked for gearless bulkers.
