Anchor AlarmSleep. Jules keeps watch.
Predictive drift detection tells real drag from a normal swing — so the alarm fires for danger, not a wind shift.
Plan around your keel. Then follow the line.
Drop a start at your berth and the Hybrid A*-APF engine plans the whole passage around your draft, tidal streams and channel fairways — completing the route even when both ends sit in shallow harbour water. Then Voyage mode guides you down the line with depth, wind and waves for every leg.
Drop the hook. Jules takes the deck.
Predictive drift detection separates normal swinging from real drag, so the alarm fires for danger — not for a wind shift. A grounding alarm cross-checks three independent depth sources. Watch your swing circle, live wind and waves, and depth from the cockpit or the restaurant ashore.
Replay your swing track and project the boat's drift hours ahead under live wind and current — straight on the anchor chart.
Ask anything, Captain.
Jules reads your live vessel state and calls 13 real data tools — weather, tides, soundings, anchorage scoring, routing, nearby vessels — then answers in your language.
