Por que os NAVIOS usam BOMBORDO e ESTIBORDO e não Esquerda e Direita?

Scientific concepts / nature & physical-phenomena involved

• Hydrodynamics & wave action

  • The ship’s bow evolved to become taller/sharper to cut water efficiently and reduce wave impacts, decreasing the risk of sailors being washed overboard.

• Mechanics of impact / ship design for warfare

  • Early bows are described as reinforced rams/rostra (e.g., with bronze reinforcement) used to split an enemy hull by ramming.

• Human biomechanics (handedness)

  • The rudder-oar placement is explained via right-handedness: placing the steering oar on the right enables stronger control.

Discoveries / historical developments / claimed “origin” mechanisms

• Problem of directional language at sea

  • Confusion around phrases like “left of whom” during battle is used to argue for standardized navigation terminology.

• Ship architecture evolution

  • Bow (front): treated as important for navigation and collision avoidance (described as painted “eyes”), later adapted for ocean cruising (speed and wave protection).
  • Stern (rear): framed as the command/logistics center (“ship’s brain”), associated with visibility and status (e.g., sterncastles).
  • Sides & steering layout: the right side is linked to rudder steering control.

• Terminology evolution (port/starboard)

  • “Starboard” is presented as deriving from Norse-era steering-oar terminology (associated with the rudder edge).
  • Docking practice: ships dock on the port side so the rudder-side oar is less likely to hit rocks.
  • “Port” is linked to older meanings related to the back side / docking side relative to steering position.

• Accident-prevention via phonetics and lighting

  • “Larboard” vs “starboard” is described as sounding too similar in storms, allegedly contributing to fatal miscommunications.
  • Navies standardized terms to be phonemically distinct and added navigation lights:
    • Green light on the port side
    • Red light on the left (starboard)
  • Color-light signaling is described as a universal visual language for preventing night collisions.

• Modern aviation “left boarding” explained by tradition

  • Planes are claimed to have passenger boarding doors on the left, attributed to maritime navigation customs carried into early aviation design.

Method / rule list (as presented)

• Day/night ship-turning / directional certainty

  • If given an order like “Turn to this side,” the ship is said to turn to the right, making the command unambiguous regardless of the captain’s perspective.

• Navigation lights (collision avoidance at night)

  • Green light assigned to one side (port side, per the subtitles’ claim).
  • Red light assigned to the other (left, per the subtitles’ claim).

• Docking practice

  • Dock on the port side because the rudder/steering oar side is vulnerable to hitting obstacles.

Researchers / sources featured

• No specific researchers, institutions, or documentary sources are named in the subtitles.

• Historical figures/groups mentioned:

  • Vikings / Norse (as the cultural origin claim)
  • Greek and Egyptian shipbuilders/artists (as examples of ship depictions with painted eyes)
  • Navies (generally, as the drivers of terminology and lighting changes)
  • Boeing, Airbus (as examples of aircraft brands)
