Abstract

Systems and methods for conveniently providing anchoring assistance onboard a watercraft are provided herein. An example system includes a display and a processor in communication with a marine system. The processor is configured to receive marine data from the marine system and/or one or more user inputs and cause the display to show one or more anchoring locations with visual indications of the anchorage quality index based on at least the marine data and/or user inputs. The one or more anchoring locations may be shown as a heat map overlaid on a map. The system may use real-time marine data, environmental data, weather data, tide data, etc. to dynamically adjust the anchoring locations and anchorage quality index. The system may enable convenient and helpful suggestions and notifications to the user when anchoring a watercraft. Some examples provide automatic deployment of an anchoring system and monitoring of a current anchoring.

First claim

The invention claimed is:

1. A system for aiding a user in anchoring a marine vessel, the system comprising:
an anchoring system for controlling an anchor of the marine vessel;
a location sensor configured to detect a current location of the marine vessel; and
a marine electronic device comprising a display and a processor configured to:
receive real-time environmental data based on the current location of the marine vessel,
determine, based at least on chart data, one or more suggested anchoring locations for the marine vessel based on the received real-time environmental data, wherein the one or more suggested anchoring locations are possible locations for the marine vessel to drop the anchor that are different from the current location of the marine vessel,
cause the display to show the one or more suggested anchoring locations,
receive one or more user inputs indicating selection of one of the one or more suggested anchoring locations; and
generate an alert for the user when the current location of the marine vessel is at the selected anchoring location.

2. The system of claim 1 , wherein the processor is further configured to:
cause the display to show the selected anchoring location in relation to the marine vessel based on the current location detected by the location sensor.

3. The system of claim 1 , wherein the processor is further configured to:
cause the anchoring system to deploy the anchor when the current location of the marine vessel is at the selected anchoring location.

4. The system of claim 1 , wherein the real-time environmental data includes at least one of weather data, wind data, tide data, and sonar data.

5. The system of claim 1 , wherein the data from the anchoring system includes a length of rode deployed.

6. The system of claim 5 , wherein the processor is configured to cause the anchoring system to deploy the anchor using a calculated length of rode based on at least depth data at the current location of the marine vessel.

7. A system for monitoring an anchored marine vessel, the system comprising:
a location sensor configured to detect a current location of the marine vessel; and
a marine electronic device comprising a display, memory, and a processor configured to:
receive real-time environmental data based on the current location of the marine vessel, determine boat profile data corresponding to the marine vessel, wherein the boat profile data includes at least one of a vessel length, bow height, a vessel draft, a number of anchors, an anchor type, a length of a line corresponding to the anchor, a scope ratio, or an allowable amount of swing;
determine an anchorage quality at the current location of the marine vessel based on the real-time environmental data and the boat profile data, wherein the anchorage quality corresponds to an anchorage quality index indicating a level of suitability for safe anchoring the marine vessel at the current location,
compare the determined anchorage quality at the current location to a predetermined threshold;
generate an alert for the user if the determined anchorage quality at the current location is below the predetermined threshold; and
receive one or more user inputs indicating another anchoring location.

8. The system of claim 7 , further comprising:
an anchor sensor for sensing an anchor within an anchoring system of the marine vessel.

9. The system of claim 8 , wherein the processor is further configured to:
determine a swing buffer distance for the marine vessel based on data from the anchor sensor, and
cause the display to show a map indicating the current location, the anchorage quality, and the swing buffer distance.

10. The system of claim 7 , wherein the marine electronic device is a multi-function display.

11. The system of claim 7 , wherein the real-time environmental data includes at least one of weather data, wind data, tide data, and sonar data.

12. The system of claim 7 , wherein the marine vessel is currently anchored at the current location.

13. The system of claim 7 , wherein the processor is further configured to:
determine a new location with an anchorage quality at or above the predetermined threshold; and
provide an indication of the new location on the display.

14. A method for monitoring an anchored marine vessel, the method comprising:
determining, based on a location sensor, a current location of the marine vessel;
receiving real-time environmental data based on a current location of the marine vessel;
determining boat profile data corresponding to the marine vessel, wherein the boat profile data includes at least one of a vessel length, bow height, a vessel draft, a number of anchors, an anchor type, a length of a line corresponding to the anchor, a scope ratio, or an allowable amount of swing;
determining an anchorage quality at the current location of the marine vessel based on the real-time environmental data and the boat profile data, wherein the anchorage quality corresponds to an anchorage quality index indicating a level of suitability for safe anchoring the marine vessel at the current location,
comparing the determined anchorage quality at the current location to a predetermined threshold;
generating an alert for the user if the determined anchorage quality at the current location is below the predetermined threshold; and
receiving one or more user inputs indicating another anchoring location.

15. The method of claim 14 further comprising:
determining a swing buffer distance for the marine vessel based on data from an anchor sensor, and
causing a display to show a map indicating the current location, the anchorage quality, and the swing buffer distance.

16. The method of claim 14 , wherein the real-time environmental data includes at least one of weather data, wind data, tide data, and sonar data.

17. The method of claim 14 , wherein the marine vessel is currently anchored at the current location.

18. The method of claim 14 further comprising:
determining a new location with an anchorage quality at or above the predetermined threshold; and
providing an indication of the new location on the display.
