Power & Thrusters
Total watts going to all 6 RIM thrusters. Default: 10,000 W.
Motor + propeller efficiency as percent.
Sea State
Total peak‑to‑trough wave height. Default: 5 ft.
Wave period in seconds. Default: 5 s.
Seawater buoyant force per cubic foot.
Stabilizer
Wetted CL for the small airplane stabilizer.
Leg Scale Rules
Baseline midpoint draft (50% of 39 ft leg). Changing this recomputes total length for NACA 0030, then scales NACA 0040 by width and NACA 0025 by equal volume.
Tune 0040/0025 drag relative to 0030 geometry baseline.
Explainer
Use the inputs to adjust math constants. The table and charts will update with a tradeoff summary across the three leg profiles.
Key assumption: Stationary or low‑speed seastead first encounters the “top half” of the wave over 1/4 of the period. The stabilizer subtracts force from that motion, then the net heave is reported.

Calculated Results Table
Heave vs. RIM Power
This chart sweeps RIM power from 2,000 W to 30,000 W and shows the final net heave for each leg profile, using your current inputs.
Speed vs. RIM Power
Speed increases with power but diminishing returns appear as drag scales with speed squared.
