Container-Optimized, Caribbean-Ready, Minimal Viable Product
The original 70-foot concept is brilliant for ultimate livability, but to launch the first commercially viable product, we must adhere to strict MVP constraints. The primary bottleneck is shipping: all structural components, floats, and assemblies must fit inside a single standard 40-foot shipping container (12m x 2.4m x 2.6m).
This MVP scales the concept down to a 20-foot equilateral-style triangle, utilizing flat-pack truss construction and modular foam/composite floats that are assembled on-site in the Caribbean. It includes only the essential systems for two people to live autonomously at sea.
Roof-mounted flexible solar panels (~2kW). 10kWh LiFePO4 bank stored under the floor deck. 3000W pure sine inverter. Enough for fridge, watermaker, comms, and RIM drives for short maneuvering.
Rear-center convertible dinette/bench that folds flat into a double bed. Positioned at the widest part of the triangle for maximum stability while sleeping.
Dual-zone 12V marine compressor fridge/freezer (approx 1.5 cu ft). Mounted mid-ship on the center-line for minimal impact on pitch/yaw.
Modular 12V reverse osmosis unit (e.g., Spectra Newport 100). Produces ~4 gallons/hour, running off the solar/battery bank during peak sun.
Forward-facing desk positioned at the very front tip of the triangle. The pilot sits directly over the front foil, experiencing zero lateral roll due to the trimaran foil geometry and active rear stabilizers.
Utilizing the 7ft height, the floor is raised 18 inches above the bottom truss chord, creating massive under-floor storage for food, clothes, and mooring screws. Overhead netting utilized as well.
| Component | Original Design | MVP Container-Ready Design | Rationale for MVP |
|---|---|---|---|
| Main Frame | 70ft sides, 35ft base | 20ft sides, 20ft base | Flat-pack truss pieces easily fit a 40ft container. 20ft base allows a 10ft RIB behind it. |
| Interior Height | 7 ft | 6.5 ft | Lowers wind profile and allows the fully assembled frame to fit inside a high-cube container if shipped vertically. |
| Legs / Foils | 19ft long, 10ft chord, 3ft width (NACA 0030) | 10ft long, 4ft chord, 1.2ft width (NACA 0030) | Three 10ft foils fit perfectly inside a 40ft container. Scale maintains 50% submersion (5ft draft). |
| Foil Bottom Slope | 5 degrees (front 10.5" higher) | 5 degrees (front 4.2" higher) | Preserves high-speed lift physics. |
| RIM Drives | 6x (1.5 ft dia), 3ft from bottom | 4x (1.0 ft dia), 2ft from bottom | Two drives on each rear leg only. Front leg is passive/pivot. Saves $10k+ and reduces complexity. |
| Stabilizers | 12ft span, 1.5ft chord, 2ft elevator | 6ft span, 1ft chord, 1ft elevator | Half-size stabilizers. Still utilize front-notch pivot and actuator elevator. Easily bolt onto rear of 1.2ft wide foils. |
| Dinghy | 14ft RIB w/ Yamaha HARMO | 10ft RIB w/ Electric Trolling/OB | Fits inside the container with the rest of the gear. Smaller, cheaper electric outboard. |
| Rear Deck | 5ft extension beyond triangle | 3ft extension beyond triangle | Just enough room to step out and access the dinghy. Flat-pack trusses. |
| Mooring | 3 Helical screws + Tension Legs | 2 Helical screws + Tension Legs | Front foil anchors to seafloor, two rear foils anchor. Triangle shape prevents yaw. Saves one expensive screw system. |
The key to a Caribbean launch is flat-pack shipping. A single 40ft container (12m long) can hold all the parts for one MVP seastead:
Assembly in Target Market: Two workers with basic rigging tools can bolt the truss frame together on a dock, attach the 3 foils, lift it with a standard travel-lift, and bolt on the stabilizers and RIM drives in the water. Total assembly time: ~3 days.
