Why Great Lakes bulk carriers invite structural concern

Very long cargo openings give Great Lakes bulk carriers exceptional capacity but leave their hulls working and twisting in heavy water.

Question

Which ship design seems least fully thought through for hazardous real-world operation?

Short answer

The very long Great Lakes bulk-carrier form worries him because its huge open cargo length permits substantial hull flexing.

Notes

Forward control spaces and aft machinery are separated by a vast, lightly subdivided cargo region. Modern forecasting, routing, and safety work reduce risk, but the basic proportions and open structure still raise concern.
