• Historical Context

"The earliest boats were simply tied up to rocks or trees on shore to take on or drop off cargo or were physically pulled onto the beach. Later, wooden structures were built out into the water to facilitate loading and unloading. Docks were also safer for ships because ships could avoid being beached, which strained the hulls and increased leaking. When the dock was extended beyond the shallows, even larger ships could be tied up, further improving efficiencies."
