Clamshell Vents

Clamshell vents are so-called because of their shape and design and are normally used as entry points for piping and wiring. They can also be used, thanks to their design, to hide hull fittings like deck drain scuppers and fuel tank vents or the top section of special through-hull vents.

Rounded Louvered Vents

Rounded louvered vents are designed to allow for airflow when venting hoses. While keeping unwanted elements out, they allow air to flow freely.

Mushroom Vents

These are vents that have a curved hood, similar to the top of a mushroom, that is primarily used to regulate air in cabins on the lower deck of boats. Mushroom vents can be adjusted as necessary by being lowered or raised. The mushroom shape helps keep rainwater and spray out while allowing air to flow freely.

Deck Vents

Deck vents, are used to allow air to flow freely through the engine area or room and any cabins on your boat with reducing the amount of sea water, spray and rain in.

Air Suction Vents

Air suction vents are designed to force air in and out of areas that require ventilation.

Cowl Vents

Marine cowl vents are specially designed vents that are normally mounted on the deck and bring air into the bilge or cabin to ensure there is ventilation. When used in combination with Dorade boxes, these vents allow air to travel freely without obstruction, while preventing unwanted water from getting into specific areas.

Thanks to their wide and cleverly-shaped openings, they allow large volumes of air to flow freely and are normally found installed protruding from the boat deck.

Louvers, also known as louvres, are vents that are designed with horizontal slats angled in such a way to keep out direct sunshine and rain. They also help, like most vents are designed to, to ensure there is sufficient airflow around different parts of the vessel.

It is important to understand that the fuel tanks used on boats are not pressurized. With this in mind, all boat gas tanks should have air vents that relieve the pressure building up while filling the tank. Generally, there is a vent line that runs sideways from the top of the tank to the hull and is angled upwards into the vent.

Ventilation in a boat can be achieved in a variety of different ways. You can use ventilators, hatches, ports, and of course vents. These design features can be used as either an air inlet or scoop, which forces more air inside your vessel or an extractor that allows a draft to freely blow throughout the boat.

Boats primarily need ventilation and vents for airflow. This airflow serves to both prevent the buildup of dangerous gasoline fumes in engine compartments and to prevent excessive moisture, mold, and mildew in other enclosed spaces like cabins.
