One missing part of the discussion is how this large ship got stuck. Brenden Greely of The Financial Times had a good possible take the other day on the Bank Effect:
Essentially, Bernoulli's Principle makes these large ships susceptible to jack-knifing in narrow canals.
Faster moving water creates a lower pressure zone. Water moves fastest near the stern of the boat. This is why the bow will tend to rise when a ship is moving quickly; the stern can bee seen as being sucked down almost.
In the Suez the 24m deep bed of the canal makes the water move very fast near the stern of the ship. This will also occur near the banks of the canal. With these very large ships, the effect is more pronounced, as there is less cross-sectional area for the water to move past.
If a ship gets near the banks, then you'll get the fast low pressure water acting on the bank-side of the stern and the bottom. Add your force vectors up, the ship torques, and does a 'wheelie' off the bank, jack-knifing the canal.
The big problem here is that these superships all are susceptible to this. It's a matter of hydrodynamics. The bigger the ship, the worse it gets. Meaning that economics comes crashing into physics, and we all know who will win that fight.
