Yes, helicopters are capable of flying over water. They have the ability to hover, move in any direction and take off and land vertically, making them well-suited for maritime operations, such as search and rescue, offshore oil and gas exploration, and transport of goods and personnel to ships and islands.
The design of the helicopter enables it to be flown over water by incorporating floatation devices, such as pontoons, that can be attached to the landing gear for water landing and takeoff. Some helicopters are specifically designed for water operations, known as amphibious helicopters, which have additional features such as retractable landing gear and waterproof electrical systems.
