It is often equipped with a mechanism, such as a pivot or a hinge, that allows the vent to be opened and closed to control the flow of air.

Because of the inherent properties of these metals, they can stand up to corrosion from salt water, moisture in the marine environment, and continual wear and tear.

Also, due to the nature of plastic, plastic vents will begin to degrade and crack over time much quicker than metal.\u003c\/span\u003e\u003c\/p\u003e \u003ch3\u003e\u003cstrong\u003eWhy should boaters install an inboard gasoline boat ventilation system\u003c\/strong\u003e\u003c\/h3\u003e \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eInstalling a ventilation system on your inboard gasoline boat is important for several reasons. First, it helps to prevent the build-up of dangerous gases, such as carbon monoxide, inside the boat's interior. These gases can be harmful to your health, and can even be deadly in high concentrations. A ventilation system helps to keep the air inside the boat fresh and safe to breathe.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eSecond, a ventilation system can help to prevent the build-up of moisture inside the boat, which can cause damage to the boat's interior and its equipment.

When the humidity level in the closed cabin rises, moisture forms, resulting in mold, mildew and musty air. In these conditions, fabrics, boat electronics and even the boat’s fiberglass structure can be damaged. By consistently replacing trapped, stale air in the closed boat with fresh outside air, the humidity equalizes from inside to outside, resulting in effective maintenance ventilation.\u003c\/span\u003e\u003c\/p\u003e \u003ch4\u003e\u003cstrong\u003eComfort Ventilation\u003c\/strong\u003e\u003c\/h4\u003e \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eCombining different types of vents, with one vent providing “intake” air flow while another vent providing “exhaust” air flow, creates cross flow ventilation. A cross-flow ventilation system will make the interior cabin more comfortable and pleasurable because air is constantly moving throughout the cabin.
