``` ### Why these specific upgrades appeal to Seasteaders: 1. **Food Independence:** While yachts stock up on food at marinas, seasteaders intend to stay out longer. Hydroponics and aquaculture are massive selling points. 2. **Security & Medical:** High-net-worth individuals on the open ocean will have concerns about piracy and medical emergencies far from hospitals. 3. **Digital Sovereignty (Tech Haven):** A large portion of the seasteading demographic is interested in escaping mainland regulations—offering private server racks and redundant satellite tracking directly targets the crypto and digital-nomad crowd. 4. **Community Docking:** True seasteading is about building floating communities. Providing modular docks allows their single-family home to eventually stitch together with others to form a floating neighborhood.
