    Charts

    • Traditional: drawn like an engraved paper chart.
    • Standard: plain.

    Charts work offline and are bought per cruising region; free during the beta.

    Charts cover United States waters: the East, Gulf and West Coasts, Alaska, Hawaii, Puerto Rico and the Virgin Islands, the Great Lakes and some inland lakes. Elsewhere the app shows land and names but no depths yet.

  • The depth after a tap on the water, with the tide now.
    The tide curve for the coming days at the nearest tide station.

    Depth and tides

    A tap on the water gives the depth with the tide now. The tide curve runs three days ahead; drag along it to see the chart at that hour.

  • The Anchor menu: Anchor, Anchor’s already down, and Stern-to.
    An anchor set: the watch circle round the anchor and the boat.

    Anchoring

    The chart can show in green the water where your boat can anchor for your planned stay; tap a spot for its depth with the tide, chain to lay, seabed slope, swing radius and clearance from charted dangers.

    1. Anchor starts it.
    2. Drop marks the spot.
    3. Set turns the alarm on. From then the app can show where the boat has swung.

    Anchor’s already down finds where the anchor went down in the last 15 minutes of track; Stern-to counts down aloud to the drop.

  • The drag alarm: the boat outside its circle and the alarm showing.

    The drag alarm

    The Android app keeps watching with the screen off. In a browser the screen must stay on.

  • A saved passage from Northeast Harbor up Somes Sound.
    The Saved tracks list: each track with its date, distance and time, and a button to export it.

    Tracks

    Passages export as GPX.

  • The grounding warning as the boat heads into shallow water.

    Grounding warning

    Sounds when the boat heads into water shallower than its draft, or, at rest, before a falling tide leaves it aground.

  • Vessels from AIS on the chart, one on a collision course in red.

    AIS and the collision warning

    Over the internet, so no receiver is needed on board. Under way, a vessel on a collision course sets off a chime.

With your crew

The crew link

Phones and tablets pair by QR code and talk directly over the boat's Wi-Fi, or over the internet when apart; in a browser it needs the internet. Messages are encrypted. Crew ashore are on the chart, each with their own track.

  • The crew screen: Sam, the captain, and three crew devices, each with how far away it is.

    One anchor for the crew

    Any device sets or raises it. Each has its own alarm, so a phone ashore can watch through one left aboard.

  • A voice call between crew devices.

    Calls and messages

    Up to 6 people on a call.

With the boat's instruments

In the Android app

From a plotter or gateway: position, heading, depth, wind, speed through the water, water temperature and AIS. The readings are kept with the track and passed to every device in the crew.

  • The Instruments settings: the switch to read the boat’s instruments, the connection, the plotter’s address and port.
    The sounder’s depth and the wind across the top of the chart, and the wind drawn over it as short streaks.

    Connections

    The app finds the plotter or gateway on the boat's Wi-Fi by itself, B&G, Simrad and Lowrance plotters included.

Sharing

A live link anyone can open shows the boat. A public boat page shows its journey a day behind, and photo posts, each placed where the boat was.

Nearby lists public boats near you. Follow a boat, or message or call another sailor. A flotilla is joined by its code.
