### (a) Explanation of 'Reserve Buoyancy' (6 Marks)
Reserve buoyancy is the potential buoyancy of a vessel. It is defined as the volume of the enclosed, watertight and weathertight space of the ship which is located above the operational waterline. It represents the vessel's ability to take on additional weight, such as from cargo, fuel, or floodwater, before being completely submerged.
**Key Characteristics and Importance:**
* **Measure of Seaworthiness:** It is a critical factor in determining a ship's seaworthiness, particularly in heavy weather. It provides the buoyant force necessary to lift the ship out of the water after pitching or rolling into a wave trough, preventing the deck from being continuously submerged.
