As of march 2021, we consider that most phones have an accuracy between 2 and 10 meters while at sea. Note that the accuracy of your position depends on your phone and your location. The app runs in the background and uses the latest Android techniques to reduce power consumption while maximizing position accuracy. Import the GPX trace of SailGrib WR if you forgot to start the application before wetting. Define a hexagonal and editable wetting zone on the screen. NEW: Use your Navionics boating charts within the app! Fix the wetting area by pressing the "Anchor" button again, it turns green. Adjust the radius of the wetting area by moving the green dot to the edge of the zone. Press the blue "Anchor" button to fix the anchor position. Center the map on the anchor point using the target sign in the middle of the screen. You should be able to detect it relatively easily on the map thanks to the reverse movement after anchoring. Return to the application.On the track, locate the point corresponding to the boat's position at the time of anchoring. Moore without worrying about the application. Start the app before your anchor, the app will record and draw your track on a map. This is why fenders are not optimal and hard-shelled buoys are preferred.Anchor Alarm by SailGrib, is a modern full featured anchor alarm app. As a result, the pulling angle at the anchor shaft is negatively affected by this floating-chain approach.įor this to work, though, it is important that the buoys do not get compressed by the water pressure when getting pulled down. The only disadvantage of the buoy system is that the anchor stays at the seabed ( ) and so eventually, the chain still needs to get down there. So, it is all kind of flipped from seabed to water level. The chain needs to get raised to store more energy, the buoys need to get dragged deeper under water to store more energy. But when looking into it more closely, it started making sense: Normally, the chain with its weight is providing the potential energy storage needed, but when the chain floats with buoys, it is the buoyancy of these buoys that is taking over this role. from the App we will mark the position of the anchor and the ship, alarm. I have never tried using a floating chain yet, and at first it seemed to me to it could not possibly work. Normally the Plotter or Gps dragging alarms are ineffective for several reasons.
