1. A method comprising:
receiving 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;
determining 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:
determining environmental factors that involuntarily cause movement of the water vessel; and
estimating, 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

transmitting the estimated location to a responder device.
