Abstract
An expandable drift sock system includes an expandable drift sock having a plurality of expansion sections configured around the circumference of the cylindrical sleeve, each having a first and second expansion portion detachably attached to each other by a section coupler. The first and second expansion portions each have an outer extension and fold portion that folds back to join with an inner extension that extends between the fold portions of the first and second expansion portions. Flaps are configured to fold over each expansion portion to hold the expansion portion in a folded configuration and to prevent water from flowing in between the folds that may produce force the stowed expansion portion to open.
