Claim 7:
8. A non-transitory computer-readable medium comprising instructions encoded thereon that, when executed by one or more processors, cause the one or more processors to perform operations, the instructions comprising instructions to:
receive a plurality of location coordinates from a user device on a water vessel at a plurality of respective times, each respective location coordinate describing a respective location of the user device at its respective time;
determine that the receiving of the plurality of location coordinates from the user device has ceased;
responsive to determining that the receiving of the plurality of location coordinates from the user device has ceased:
determine environmental factors that involuntarily cause movement of the water vessel; and
estimate, at a determined cadence, the location of the user device based on the environmental factors and at least a portion of the plurality of location coordinates, the determined cadence increasing where the environmental factors correspond to faster movement of the water vessel and decreasing where the environmental factors correspond to slower movement of the water vessel; and

transmit the estimated location to a responder device.
