The canal can handle more traffic and larger ships than the Panama Canal, as Suezmax dimensions are greater than both Panamax and New Panamax . Some supertankers are too large to traverse the canal . Others can offload part of their cargo onto a canal - owned boat to reduce their draft, transit, and reload at the other end of the canal . </P> <P> The canal has no locks because of the flat terrain, and the minor sea level difference between each end is inconsequential for shipping . As the canal has no sea surge gates, the ports at the ends would be subject to the sudden impact of tsunamis from the Mediterranean Sea and Red Sea, according to a 2012 article in the Journal of Coastal Research . </P> <P> There is one shipping lane with passing areas in Ballah - Bypass near El Qantara and in the Great Bitter Lake . On a typical day, three convoys transit the canal, two southbound and one northbound . The passage takes between 11 and 16 hours at a speed of around 8 knots (15 km / h; 9 mph). The low speed helps prevent erosion of the banks by ships' wakes . </P>
