The seastead is already very stable. For the customer who demands near-perfect stillness while coding, trading, or writing, we offer two tiers of workstation stabilization.
No power required • Simple • Reliable
The entire workstation (desk, chair, shelves) sits on a precision 2-axis gimbal ring with a heavy tuned counterweight hanging 4 feet below. Viscous rotary dampers control movement. The natural pendulum period is tuned to ~8–10 seconds — well outside typical Caribbean wave frequencies (3–6 seconds).
Four industrial air springs with magnetorheological (MR) fluid dampers. The dampers can be manually adjusted (or use a simple mechanical valve) to tune stiffness and damping. Excellent at isolating high-frequency vibration from the RIM thrusters and wave slap.
Real-time motion cancellation • Near-perfect stillness
The workstation sits on a compact Stewart platform (6 electric linear actuators) controlled by a high-speed industrial IMU and Raspberry Pi 5 / ROS2-based controller. The system predicts and counters motion 200 times per second. The user experiences what feels like a completely stationary desk.
