Measure currents
Current Measurements Section
This section is equipped with several tabs designed to help you interact with and understand the day's current measurements.
START
To accurately measure the current, you will need a floatable object referred to as a "current stick". This could be a bottle filled to three-quarters capacity, an apple, or even a sponge.
Follow the steps outlined below to carry out your current measurement:
Prepare Your Current Stick: Ensure your chosen object is ready to be used as a current stick. It should float well and be visible on the water.
Release the Current Stick Upwind: Carefully drop your current stick into the water upwind of your position. This allows it to naturally drift with the current, providing an accurate measurement.
Allow the Current Stick to Drift: Let the current stick move freely, ensuring that your boat doesn't interfere with its path. It's important not to disturb the natural flow of the water around the current stick.
Wait for Two Minutes: Allow the current stick to drift for two minutes. This time frame allows for an accurate reading of the current's direction and speed.
Return to the Current Stick: After the two minutes have passed, maneuver your boat back towards the current stick, aiming to approach as closely as possible to the point where you originally dropped it.
Record the Measurement: Once you're back in position, hit the 'Stop' button. The system will then calculate and display the current's direction and speed based on the movement of the current stick.
By following these steps, you will obtain a reliable measurement of the water current, contributing to safer and more effective navigation.
* Recomended at the begining do more than one sample to see if you get similar results* With light currents add more time to the sample time to be sure
EXAMPLE
This tab provides the option to initiate a sampling process.
Reset Sample
If at any point during the sampling process you notice an anomaly or interference, such as another coach boat coming too close, you have the option to reset the sample. This function immediately stops the current sampling session and clears the data, allowing you to start a fresh, uncorrupted sample. This way, you can ensure that your measurements are as accurate and reliable as possible, free from any unintended influences.
Stop Sample
To finalize the sampling process, you can use the 'Stop Sample' function. This action concludes the current sampling session and secures the data collected during that period.
Upon stopping the sample, the system will automatically navigate you to the 'LAST' screen.
LAST
The 'LAST' tab allows you to review the most recent sample taken. On the left side of the screen, you will find details about the sample's duration, along with the initial time and date when the sampling session began.
The display units for both direction and speed can be customized according to your preferences. These settings can be adjusted in the 'Settings' section of the application, ensuring the data is presented in a format that is most intuitive and useful for your specific needs. This tailored approach makes it easy to understand and analyze the latest sampling data.
LIST
The 'LIST' tab presents a comprehensive catalog of all the samples taken during the day. Each individual sample is represented with its specific details, allowing you to easily navigate and review the data captured throughout your sailing session.
Moreover, this section also provides the functionality to delete any sample from the list. Whether a sample was taken in error, contains inaccuracies, or is simply no longer needed, you can effortlessly remove it from your daily log, ensuring your data remains relevant and organized.
MAP
The 'MAP' tab offers a georeferenced visual representation of your samples. Here, each sample is plotted according to its geographic location, providing a spatial context to your data and enabling a more intuitive understanding of how conditions vary across different areas.
If you have an internet connection, this feature is enhanced with the integration of Bing Maps as a background layer. This allows for an even more detailed understanding of the sampling locations, as you can correlate the data with specific geographic features and landmarks shown on the map.
