The operating system for your boat.
Charts, ensemble weather, isochrone routing, and a copilot you talk to over the VHF — all running aboard. The cloud is the convenience and the heavy lift, never the dependency. Cut the signal and the boat still works.
Every capability declares what it does when the network is gone. Offline degradation is a protocol guarantee, not a hope.
Photorealistic 3D tiles online, free-data charts cached for the whole corridor underneath — signal loss swaps source, never goes blank.
offline: cached corridorECMWF and GFS ensembles, currents, tides, and storms as one normalized field model — the same data the router reads.
offline: last field + ageFifty-one members finding the optimal passage. P5/P50/P95 arrival envelopes, risk metrics, departure windows — not a rhumb line with a wind arrow. Sovereign boats run the same engine locally.
offline: local engineAgentic crawl, summarize, and cite for anchorages and landfalls — pre-fetched for your destination before you lose signal.
offline: cached reportsPick up the handset and ask. The same engine that monitors the VHF and transcribes every call hears you — your boat's voice copilot, on the handset you already own. One tap to confirm. Never auto-transmits.
offline: local whisperOpt-in, anonymized conditions sharing. Contribute observations, get the fleet's back. No identity, no tracks, ever.
