@JL_Frusha - the bow displaces the mass of water sideways when cresting a wave, gravity causing the boat (or Ramform) to plow through the crest rather than floating over it.
But that effect (displacement ... caused by gravity) is different from the refraction of surface wave energy, in that displaced water fills the void behind the boat as it moves forward and refracted energy does not.
Surface wave energy is refracted at an angle, and that energy wave then continues in that new direction.
So the Ramform uses gravity to displace water and position the Ramform's bow below the water surface ... and that below-surface position consequently allows the Ramform's bow to refract wave energy.
To be beneficial for a Floating City, the energy of the surface wave must be refracted by the Ramform away from the city platforms (or dissipated via energy transfer ... e.g., using turbines to generate electricity).
A tethered Ramform rotates around the tether, refracting surface wave energy away from the energy shadow (the area behind the Ramform's stern).
What is the plan for continuously moving the Floating City, so that it remains in that energy shadow?
