I salute your efforts, @JL_Frusha, and agreed that scale models are a helpful (if not mandatory) step in proving the concept.
I'm with you in spirit.
My thoughts are relevant to the physics of the problem (of protecting a Floating City), as opposed to critiquing the design of the Ramform (which doesn't appear to be designed primarily for Floating Cities).
Here's how I see that in practical terms.
Wave energy is wave energy, regardless of the shape of a hull. Prior to impacting an object (of any shape), a surface wave is simply that ... a surface wave. The appropriate physics apply.
While a boat moving through water certainly impacts whatever wave energy exists, the design of a bow is to displace water to the side of the hull.
The various designs of bows achieve various performance results, but the objective is always related to water displacement.That's what bows do ... displace water along the longitudinal axis of the hull.
But Floating Cities are not concerned with any displacement except their own floating structures.
Floating Cities are concerned about surface waves (the energy ... not the mass), because surface wave energy creates swells relative in size to the waveform. We see that in the amplitude ... 1/2 the distance of the crest-to-trough measurement.
Measured from the [calculation of what would be a] flat surface, the amplitude is the height of the swell. The wave (energy) also extends equally below that flat surface ... which is the trough. Beyond that depth, the Floating City need not concern itself with the energy of surface waves.
The function of a Floating City's Ramform is not to displace water, but to refract the energy of the surface waves away from the Floating City ... resulting in the minimization of swells in the area upon which the Floating City floats.
The surface waves (energy, not mass) don't flow back around the edge of the Ramform to "fill the hole", as happens with displacement. The energy refracted from the hull (the edges) of the Ramform heads off in a new direction and never affects the Floating City again. That energy goes somewhere, but not to the Floating City.
(This is why the leeward sides of islands have smoother surfaces than do the windward sides. It is also how Polynesian sailors traditionally navigate.)
Thus ... no surface wave energy, no swells.
If the Ramform is not as deep as the amplitude, then some of the wave energy will pass under the lower edge of the Ramform's hull and resurface behind it, visible as a series of swells moving on toward the Floating City ... depending on the wave parameters and the length of whatever section of the Ramform under which the wave's energy is passing.
So ... unless your Ramform extends down to (at least) the amplitude of your largest potential physical waves (swells of water rising above the water surface) ...
... your Ramform (of the V-shaped design in the photos on this thread) will not keep your Floating City from being tossed, to some degree, by the storm swells. The hortizontal depth (bow to stern) of your Ramform's "wings", incidental to the direction of the surface wave, are far too narrow for that.
An artificial kelp or mangrove forest could deal with that residual wave energy, but that's a slightly different subject.
The weight of the Ramform is what keeps it partially submerged, which consequently allows the submerged portions to refract surface wave energy.
The shape of the bow allows water in the swells to be more effectively displaced sideways, and gravity is the force that determines how much of the swell will be displaced by the bow and hull (i.e., how low the Ramform's bow will ride in the water and cut through the swell).
