Seastead Kit — Packed in a 45′ High Cube Container
Seastead Kit — 45′ HC Container Packing
Interior envelope 44.6′ × 7.7′ × 8.9′ (grid = container floor, container hidden).
Drag to orbit · wheel to zoom · hover parts for specs · click legend (or a part) to isolate.

Rear (closed end) at left, container doors at right.
Two foils nest spoon-style (one inverted) against the right wall at the back; the third foil
lies ahead of them. Three 44′ wall sections stand along the left wall.
Rough packed-weight estimate ≈ 41,000 lb — about ⅔ of the 62,000 lb payload rating.

**What you'll see**
- **The 3 foil floats** modeled as true NACA 0035 sections (8.5′ chord truncated to a blunt 8.0′ trailing edge), extruded to 21.5′. Two are nested spoon-fashion (one inverted) against the right wall at the back, exactly as you described; the third lies ahead of them near the container doors. Each has its trailing-edge wire conduit and shipping dunnage.
- **The three 44′ wall sections** standing upright along the left wall with frame trim.
- **Everything else** packed in the remaining spaces: six 22′ beams on the corridor floor with batteries, inverters, thrusters, heave plates, the deflated dinghy, outboard and mooring gear above them; solar panels, deck grating, railings, braces, and door slabs in the "attic" layer above the walls and foils.
**Interactive features**: orbit/zoom, hover tooltips with specs, a clickable cargo manifest that isolates any part, part labels (toggleable), an optional dashed envelope outline (off by default since you didn't want the container shown), auto-rotate, and an **explode-view slider** that pulls the packing apart so you can inspect how tightly it fits.
One honest observation from building this: two nested NACA 0035 foils only compress to ~5 ft of combined width (their max-thickness points are at different heights, but the interlock is limited), so the center corridor exists mainly along the front half next to the single foil — which is where I put the beams and heavy cargo. If you'd like, I can produce a variant exploring alternative nesting (e.g., foils lying flat, or walls thinner than 10″) to free up more center space.
