There must be more to it than that. Using that formula, if I loaded my boat so it sat deeper in the water

To a degree, that is true. For a while the sail racing
rules ranked boats based on there LWL, so racers started buying
boats with huge overhangs fore and aft. When the boat was rated at the dock
, it was rated as being slow due to the short LWL but when healed over, the overhangs were in the water
effecitvely increasing the LWL and the hull speed
