AI Note: While I cannot visually process the specific video footage linked, I can apply standard marine engineering principles and Froude scaling laws to your exact dimensions to provide the requested analysis. The estimates below are based on the physics of your specific multi-column design.
Based on typical lake/harbor test environments for scale models, small wind chop or boat wakes usually range from 4 to 10 inches in height.
Your design is effectively a Semi-Submersible / Spar platform. The defining characteristic of this setup is a very small waterplane area (the area of the floats intersecting the water surface) compared to its total mass and displacement. Here is how its motion will compare in 3-to-6 foot full-scale waves:
| Vessel Type | Motion Profile & Wave Interaction |
|---|---|
| 60' Triangular Seastead | Decoupled from surface. Because the columns are only 4ft in diameter, wave energy passes through the structure rather than lifting it. It will pitch and heave very slowly with a long natural period. It will "punch through" 3-6 ft waves with almost no vertical movement, provided the waves do not hit the underside of the deck. |
| 60' Monohull | Wave Contouring. A monohull has a large waterplane area heavily influenced by buoyancy. In 3-6 ft waves, the bow will rise and fall with the wave slope (pitching). If taking seas on the beam, it will roll continuously like a pendulum. |
| 50' Catamaran | Stiff and Snappy. Catamarans are highly stable but have massive waterplane area spread far apart. A catamaran acts like a raft—it actively tries to stay parallel to the wave surface. This means it follows the wave contour exactly, resulting in very jarring, rapid side-to-side movements (high roll frequencies). |
In marine design, human comfort is dictated by acceleration, usually measured in g-forces. The threshold for seasickness is sustained accelerations above 0.1g to 0.15g, particularly at low frequencies.
Froude Scaling Rule for Acceleration: One of the most counter-intuitive but mathematically true rules of Froude scaling is that acceleration is 1:1. The acceleration your camera experienced on the 1/6th scale model is exactly the same acceleration a human would feel on the full-scale seastead!
There is one exception to the seastead's low-acceleration profile. If a wave is high enough to hit the flat underside of the main triangular deck (an event known as "slamming"), the accelerations will instantly spike, violently jarring the structure. When building the full-scale version, ensuring a high air-gap (the clearance between calm water level and the bottom of the deck) is the single most critical factor for maintaining the smooth ride your scaled model demonstrates.
