The countdown to SeaPerch 2021 is on. This annual underwaterrobotics event is back on Saturday, 13 March. Twenty-four teams from nine schools across Cayman are expected to compete in this year’s challenge, which includes a timed obstacle course, a mission course requiring a "waterway clean-up" that entails disarming an imitation active naval mine, opening and closing an underwater disposal vault, and collecting and disposing of various floating and sunken debris.
