A solar-powered, small-waterline-area seastead — designed to pack into a single 45-ft High Cube container for global shipping.
| Parameter | Value | Notes |
|---|---|---|
| Shipping Container | High Cube 45 ft | 7.7' W × 8.9' H × 44.6' L · Max 62,000 lbs |
| Main Triangle Frame | Equilateral ▵ 44.0 ft per side | Also forms the living-area wall; 7 ft floor-to-ceiling |
| Living Area | Enclosed triangle interior | Minus 5 ft at each corner (covered deck) & 3 ft exterior walkway |
| Legs / Foils | 3 × NACA 0030 foil | 14.5 ft long, 8.5 ft chord; last 0.5 ft of TE removed to fit 8.9' container height |
| Leg Orientation | Blunt leading edge forward | 50% submerged (7.25 ft draft), 50% above water; ladder on upper front half |
| Thrusters | 6 × RIM drive, 1.5 ft ø | One each side of each leg, ~2 ft up from bottom; flat sides fore/aft |
| Stabilizers | 3 × "little airplane" stabilizers | 10 ft span, 2 ft chord; body 6 ft; elevator 2 ft span × 6" chord · servo-tab actuated |
| Power | ~25% displacement = LiFePO₄ batteries | Low in legs; triple-redundant per-leg inverter/charger; solar on roof |
| Dinghy | 14 ft RIB (deflated) + Yamaha HARMO electric OB | Sideways at center-back; shielded by living area when underway |
| Container Packing | 3 legs end-to-end (TE up, right side) + 3 wall sections (left side) | Ample center room for all other parts |
The MVP seastead includes everything above but with a fixed stabilizer (simple heave plate) and without the following optional extras. It is a comfortable, spacious, low-cost, solar-powered yacht — ready for family enjoyment and sea trials, and potentially for sale as-is.
These extras make the seastead more fun, capable, and community-ready. Each has been thought through for stability, redundancy, and quality of life at sea.
Replaces the fixed heave plate with the full "little airplane" stabilizer using a servo-tab elevator. A small actuator adjusts elevator angle, changing main-wing angle of attack without a large actuator. Notch into the wing's leading ~25% chord lets the center of lift balance on the pivot, even where the leg is thin.
🔗 stabilizer.trimaran.htmlThree helical mooring screws driven into the seabed. The seastead becomes nearly stationary when parked, using tension legs for a stable, quiet platform — ideal for longer stays or sensitive equipment.
🔗 tension.leg.structure.htmlA kite-flying device rides a track around the top of the walls (curved at corners). Provides backup propulsion and a stunning visual. The kite robot can harness wind energy for supplementary thrust or simply for recreation.
🔗 kite.robot.core.htmlTwo seasteads connect via a walkway, one behind the other. Both computers coordinate thrusters and stabilizers to minimize walkway movement — especially when warned that someone will be crossing. Enables a real floating community.
🔗 ship.to.ship.transfer.core.htmlMultiple seasteads travel together in formation. Coordinated thrusters and stabilizers across the convoy reduce collective drag and improve stability. The computers share data to optimise the group's movement.
🔗 convoy.mode.core.htmlBased on customer needs, liveaboard trends, and the seastead's unique architecture, here are other extras that could broaden appeal:
Watertight, streamlined pods that mount beneath the triangle frame between legs. Great for dive gear, provisions, or seasonal equipment without cluttering the living space.
storageA retractable platform between two legs at water level, with a wide ladder. Perfect for swimming, snorkeling, or boarding from the water.
recreationGutters integrated into the roof edges channel rainwater into a filtration system and storage tank. Reduces reliance on shore water — ideal for long passages or remote anchoring.
sustainabilityUpgraded insulation, reflective roof coating, and sea-water heat exchangers allow air conditioning to run with minimal power draw. Keeps the interior cool and quiet.
comfortIntegrated Starlink Maritime dish with a dedicated low-power router, external antenna mast, and a cellular booster for near-shore use. Keeps you connected anywhere.
connectivityA dedicated corner with rod holders, a bait prep surface, freshwater rinse, and tank rack storage. Turns one covered deck into a serious fishing or dive base.
sport360° cameras, radar reflector enhancement, AIS transponder, and motion-activated lighting. Peace of mind whether anchored or underway.
safetyA compact workbench with vice, tool storage, and a 3D printer nook. For the hands-on seasteader who wants to fabricate repairs or custom parts at sea.
diyA vertical growing system inside the living area using minimal water. Grow herbs, leafy greens, and small vegetables year-round — fresh food without a fridge.
