Description
The current channel depth of the canal allows for a maximum of 20.1 metres (66 ft) of draft,
The typical deadweight of a Suezmax ship is about 160,000 tons; the typical beam (width) is about 48 m (157.5 ft). Also of note is the maximum head room—"air draft"—limitation of 68 m (223.1 ft), resulting from the 70 metres (230 ft) height above water of the Suez Canal Bridge. Suez Canal Authority produces tables of width and acceptable draft, which are subject to change.[1] From 2010, the wetted surface cross sectional area of the ship is limited by 1006 m2, which means 20.1 metres (66 ft) of draft for ships with the beam no wider than 50.0 m (164.0 ft) or 12.2 metres (40 ft) of draft for ships with maximum allowed beam of 77.5 metres (254 ft).[3]

Aframax is a freight rating, not a geographic routing limiter, for tankers are those with a capacity of 80,000 tonnes deadweight (DWT) to 120,000 DWT.
Container ships
Vessels longer than 400 meters need permission from the Suez Canal Authority to transit the canal. As of 2020, the largest container ships in service all have a length of (close to) 400 meters, and a beam and draft that fit just within the limits of the canal.[4][5] The ship Ever Given, which ran aground in the Suez Canal in 2021, has Suezmax size with 399.9 meters length and 58.8 meters beam.[6]
