No wonder that enjoying clean air either on the deck or in the cabin of your boat is of great importance to all mariners. In order to maintain a healthy atmosphere on your boat, take good care of equipping your vessel with reliable ventilation systems as well as durable and exactly fitting boat hatches. In this way, controlling moisture and preventing mold, getting rid of smells and allowing for continuous flow of fresh air will become an easy thing to do.
The importance of healthy on-board climate cannot be overestimated, that is why keeping the air you breathe always clean is a job that can be trusted to only the most dependable equipment. If the ventilation system on your boat is not performing in a proper way, it is time to consider looking for a more efficient substitute. At our web store, you will find a complete range of fans, vents, blower motors and other products that will help you deal with stuffy air, excessive moisture or even gasoline fumes. Deck ventilators, shell, electric, cowl and extraction ventilators, air suction vents and accessories are available here.
Stainless steel deck ventilators are usually available in mushroom configuration, thus being easily opened and closed. Deck ventilators come in a variety of sizes, featuring mosquito nets and waterproof qualities. Shell ventilators take their name from a characteristic clam shape and are screwed directly onto the hull either vertically or horizontally. Free flow area of shell deck ventilators normally ranges from 3 to 6.4 square inches. Cowl vents have large up to 19 square inches flow area, manufactured from flexible PVC that is considerably safer than rigid materials and thus ensures long service life of the unit.
We also carry a range of marine hatches, from low and medium profile to offshore and access hatches, and a choice of lenses, screens, and shades. Most common hatch sizes used on most boats are 19x19, 16x16, 18.5x18.5 and 10x10 inch units. Apart from a range of the available size options, you will also be able to pick different frame designs, colors, and latch configurations. Most hatches feature rigid construction with self-supporting lid that can be adjusted in different positions up to 95 degrees. When closed, the hatch will ensure leak protection, while when open it provides unrestricted air flow to the inside of your boat.
