Tack and gybe

What you get

On board

• Logbook: “Tack” or “Gybe” line with its own symbol, time and place, about 30 to 40 seconds after the manoeuvre. The time is the moment the wind changes the side of the boat.
• “Maneuvers” filter shows or hides all tacks and gybes.
• Map: tack and gybe symbols at the place of the manoeuvre, across the whole stored history. You switch off the “Maneuvers” layer in the map layers. Tapping opens the manoeuvre analysis.
• Swiping in the logbook additionally shows “Maneuvers” for tacks and gybes, for the manoeuvre analysis.
• In the PDF logbook tacks and gybes appear as separate lines.
• Motorboats (from 1.48.0): If your boat is set to “Motorboat” in the boat configuration, the app shows no tacks and gybes, neither in the logbook nor on the map, and offers neither the “Maneuvers” filter nor the “Maneuvers” prompt category. The PDF logbook leaves them out as well. If you set the boat type to “Sailboat”, they appear again.
• Adapts: If you later add “Sailing” because the engine was wrongly detected, the tacks and gybes of that time come back into the logbook. If you set “Motoring”, they disappear (see Self-correction).

Remotely

• If you connect the Hub to the cloud, you see the same entries in the logbook and on the map, and so do your Boat Buddies. From the number of manoeuvres you can also see from home whether the boat is currently beating.

How it works

• Nothing to switch on. Detection runs while under way as soon as a wind sensor supplies data.
• Entering yourself (sailing boats): on board, connected to the Hub, ”+” › “Quick Entry” › “Tack” or “Gybe”. Your entries always stay, even under engine.
• Deleting a wrong detection: on board, swipe to the left under Menu › “Ship’s Log” and delete. The Hub does not enter a deleted manoeuvre again.

Requirements

• Wind sensor on the onboard network that supplies the apparent wind. Without a wind sensor the Hub detects no manoeuvres.
• Course over ground is supplied by the Hub’s own GPS.
• No internet, no account, no subscription.

Permissions and subscription

• Subscription: fully usable without a subscription; the Standard subscription adds nothing extra.
• On board: Everyone connected to the Hub sees, deletes and sets entries.
• Remotely: you and your Boat Buddies see the entries and the manoeuvre analysis.

Notifications

• No push notification for a tack or gybe.
• Prompt on board only on request: Under Settings › System › “Detected logbook entries” you switch on the “Maneuvers” category. The app then asks for every detected manoeuvre “‘Tack’ detected!” with “Confirm” and “Deny”; “Deny” deletes the entry. The category is off by default, and on motorboats it does not exist from 1.48.0.

Messages and special cases

The feature has no error messages of its own.

Offline behaviour

• Detection and entry work without internet. If you connect the Hub to the cloud, it receives the entries as soon as the Hub has internet again.
• If the Hub restarts, a manoeuvre that was just being checked or fell in the first seconds after the start is lost. Manoeuvres already detected are kept.
