Good ventilation aboard provides a number of benefits to both the crew and passengers. It provides a source of fresh air in any weather conditions, helps to prevent bad odors and mildew, and can even save somebody's life by removing carbon monoxide in the case of an emergency. If a non-open vessel is outfitted with a gasoline inboard motor, the ventilation system having a blower is a legal requirement. Commonly, the vent layout includes special channels (ducts) that have openings known as air inlets and outlets. Typically, these openings have different kinds of plastic or metal vents available in various shapes and designs.
There are louver, cowl, mushroom, and other types of vents that can be installed on the deck, walls, or other constructions. The square of vent holes and their location have to meet specific requirements. For instance, air outlets should be installed above any possible bilge water level. In our online store, you will find a large assortment of boat vents offered in different kinds and sizes. They are made from high-quality plastic, stainless steel, brass, or other materials and feature appealing finishes, so you will certainly find the products that suit your project best.
