What is the purpose of a cowl in a ventilation system?

The purpose of a cowl in a ventilation system is to scoop in air. In the context of marine applications, a cowl typically refers to a hood or cover that directs airflow into certain areas, helping to ensure that fresh air is supplied to critical components, like the engine or living spaces. This airflow is essential for maintaining proper ventilation, which can help prevent overheating, reduce fuel vapors, and improve overall engine performance. By effectively channeling air into the system, the cowl plays a crucial role in supporting the proper functioning of the vessel and enhancing safety for everyone aboard.
