# 11.5 Technical Inspection Team’s vessels are to be tested in the following before they are allowed to compete: * **Propulsion**: All batteries must be sealed to reduce the hazard from acid or caustic electrolytes. The open circuit voltage may not exceed 60V \[DC]. All battery cells used in the competition must be commercially available. * **Visual Indicators:** The vessel's visual indicators, such as lights and flags, will be tested to ensure that they are visible and functioning correctly. * **Kill switches:** An emergency stop mechanism, also known as a kill switch, will be tested to ensure that it is working properly and that the vessel can be shut down quickly in case of emergency. * **Hull specification:** Dimensions within the recuirements. Other components that may be tested include navigation and communication systems, safety equipment, and overall compliance with competition regulations. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
