Seastead Optional Extras

Customize your ocean freedom. Upgrades designed for the MVP and beyond.

Our minimal viable product is designed to provide everything a single family needs for life on the water. However, every ocean dweller has unique needs. Here is our roadmap of optional extras, specifically tailored to complement the triangle truss, NACA foil floats, and open porch design of your seastead.

💧 Water & Sustainability

Off-Grid

🌧️ Rainwater Catchment System

Custom guttering integrated into the roof edges that channels rainwater directly into a multi-stage filtration and storage system housed within the 7-foot truss structure.

Essential

🔄 High-Capacity Watermaker

Reverse osmosis desalination unit powered by your solar roof. Ensures total water independence, converting seawater into pristine drinking water.

Food

🥬 Porch Hydroponic Garden

A modular, salt-spray-resistant hydroponic setup for the covered porch area. Grow fresh herbs and vegetables using integrated drip irrigation.

⚡ Power & Propulsion

Performance

🪂 Towing Kite Sail

A deployable parafoil kite system attached to the front of the triangle frame. Harnesses higher altitude winds to drastically reduce battery drain on the RIM thrusters during long transits.

Efficiency

🌬️ Truss-Mounted Wind Turbines

Vertical-axis wind turbines designed to mount seamlessly into the 7-foot truss framing. Provides power generation at night or during storms when solar is inactive.

Upgrade

🔋 Extended Battery Banks

Additional marine-grade LiFePO4 batteries mounted low in the NACA foil legs to lower the center of gravity and extend off-grid duration during cloudy weeks.

🏝️ Outdoor & Porch Living

Comfort

🛁 Saltwater Hot Tub

A compact, hull-integrated tub on the back porch. Uses waste heat from the RIM drive thrusters and battery banks to provide warm, luxurious soaks under the stars.

Recreation

🛝 Porch Drop-Slide

A rugged marine-grade slide attaching to the porch railing, providing instant, fun access to the water for swimming, right above the front leg ladder.

Shade

Retractable Porch Awnings

Motorized canvas awnings that extend over the open porch areas, providing vital shade in tropical latitudes without blocking the ocean breeze.

🤿 Ocean Access & Recreation

Diving

🫧 Hookah Dive System

A floating air compressor system stored on the porch. Allows unlimited diving beneath the seastead to inspect foils or clean the hulls without needing SCUBA tanks.

Fishing

🐟 Integrated Fish Cleaning Station

A fold-down stainless steel table mounted on the back porch near the RIB storage, complete with a saltwater washdown pump and bait freezer.

Utility

🤖 Underwater ROV

A small tethered ROV garaged near the leg ladders. Essential for checking the stabilizer "airplanes", thruster intakes, and NACA foil bottoms without getting wet.

🛟 Safety, Navigation & Maintenance

Navigation

📡 Autonomous Station-Keeping

Advanced GPS and weather-routing software that automatically pulses the RIM drives to hold the seastead in an exact coordinate, acting as a virtual anchor.

Vision

🔍 FLIR Night Vision Camera

Thermal imaging mounted on the front point of the triangle. Essential for spotting unlit vessels, debris, or marine life during night transit or at anchor.

Maintenance

🔊 Ultrasonic Anti-Fouling

Emitters mounted inside the NACA foils that emit high-frequency sound waves, preventing barnacle and algae growth on the leading edges and thruster intakes without toxic paints.
