Anchor watch

What you get

On board

• Watch on the Hub: The Hub compares every position of your boat with the anchor point and circle, even if your phone or tablet is off or the app is closed.
• Alarm at the Hub: The Hub beeps without pause until your boat is back in the circle, you mute it or you raise the anchor. Its alarm output switches in the same rhythm; you connect a horn, a flashing light or a relay to it (at most 500 mA, output voltage like your boat’s electrical system, use a relay for larger signal devices).
• Anchor LED on the housing: lights up as long as the watch is active.
• Sounds when operating: when setting, the Morse code for “understood” (short, short, short, long, short), when raising, the Morse code for “end” (short, long, short, long, short), three short tones if the GPS fails.
• Alarm in the app as long as it is open and connected to the Hub: notice with alarm sound and vibration, buttons “Mute” and “Raise” (see Notices in the app).
• On the chart: anchor symbol, circle, line from the boat to the anchor and at the top left the display “Anchor watch active”, red during an alarm.
• “Anchor Watch” sheet when you tap the circle: distance to the anchor, latitude and longitude of the anchor, true and relative bearing to the anchor, safe radius.
• Menu › “Alarms”: “Anchor Watch” card with a small chart, status, distance (green inside the circle, red outside), safe radius, bell for the app’s alarm sound and a switch for raising.
• Plotter instrument “Dist. Anchor”: distance to the anchor, green inside the circle, red outside.
• Logbook: Setting, changing, raising, alarm, all clear, GPS lost and back appear automatically in the logbook, also in the PDF.

Remotely

• Push notification to you as the owner for alarm, all clear, GPS loss and GPS return (see Notifications).
• Boat monitoring: “Anchor” tile with “Off”, “Watching” or “Alarm”, chart with anchor position and circle. Your Boat Buddies see this too.
• Logbook: the watch’s entries also appear in the cloud.

At the berth as geofencing

• Set the anchor watch on the pontoon or at the mooring just like at anchor. If your boat leaves the circle, the Hub sounds the alarm and you get the push notification, without a subscription over Wi-Fi, with the Standard subscription also over Hub cellular.
• Your onboard electronics may be off. The Hub then uses its built-in GPS.
• Independently of the watch the Hub reports every departure: if you connect the Hub to the cloud, you and your Boat Buddies get a push notification ”⛵ Departure” as long as the Hub is running (see Trip and berth detection). This notification arrives about 8 minutes after casting off, the watch’s alarm after 15 seconds.

How it works

Setting the anchor watch (on board)

1. Connect the app to the Hub.
2. Open the chart in the Plotter or, under Menu › “Alarms”, the “Anchor Watch” card. The chart has to show the current period, not a past trip.
3. Tap on the water next to your boat, at most 100 m away. The sheet shows the distance.
4. Tap “Set Anchor Watch”. The anchor lies at the tapped spot. The app suggests the circle: distance to the boat plus 10 m, rounded to 10 m, at least 20 m, at most 100 m. Then you adjust it anywhere between 10 and 100 m (see “Changing the circle”).
5. The Hub confirms with the Morse code for “understood”, the anchor LED turns on.

Moving the anchor

• Press and hold the anchor and drag it to the new spot. The circle stays the same.
• Or tap on the water again and set the watch anew. Position and circle are replaced.

Changing the circle

• Tap the circle and choose the safe radius from 10 to 100 m in 10 m steps in the “Anchor Watch” sheet, or change it under Menu › “Alarms”.

Muting

• During an alarm: “Mute” in the alarm notice or in the “Anchor Watch” sheet. The Hub and alarm output are silent, the app no longer plays an alarm sound, and no further alarm notification is sent.
• Only your phone’s alarm sound: bell on the “Anchor Watch” card under Menu › “Alarms”. This applies to this phone only, the Hub keeps beeping.

Raising

• Tap “Raise” in the “Anchor Watch” sheet or in the alarm notice, or switch the switch under Menu › “Alarms” off. The Hub confirms with the Morse code for “end”, the LED turns off.

Requirements

• A Smartboatia Hub on board with GPS reception. It uses the position from your onboard device or its built-in GPS (see Data source priority).
• For setting and operating: app connected to the Hub. No internet, no account, no subscription.
• For push notifications: Hub connected to the cloud and internet at the Hub, without a subscription over a Wi-Fi with internet (marina Wi-Fi, router on board or hotspot of a phone or tablet), with the Standard subscription also over Hub cellular where there is a network (Hub cellular coverage map). On your phone or tablet the Smartboatia app version 1.30 or later, signed in with your Smartboatia ID and with notifications allowed (see Push notifications).

Permissions and subscription

Safety notice

Notifications

• There is no push notification for setting, changing, raising and muting.
• All clear and GPS messages also arrive if you have muted the alarm.

Messages and special cases

Offline behaviour

• Without internet the watch works entirely on board: Hub alarm, alarm output, LED, notice in the app and logbook. Push notification and remote view are there if you connect the Hub to the cloud and it has internet, with the Standard subscription also over Hub cellular. Data only goes to the cloud if the Hub is connected to it.
• Hub restart: Anchor and circle stay saved, the watch is active again immediately afterwards. A mute is cancelled by it. If your boat is still outside, the alarm starts again after 15 seconds.
• Alarm sound in the app: The bell setting stays saved on your phone or tablet until you switch it again or set a new watch.
