Proper ventilation of a boat’s tight, enclosed areas is important. It means a longer lifespan for fabrics and storage items as well as enhanced customer satisfaction. From Vico Marine, the Boat Vent AERO is a sew-in venting cap that brings air flow into humid spaces. The boat cover vent is specially designed to prevent mold and mildew from forming. Simply cut a hole in your fabric and sew the cap into the fabric. It is great for use in covered boat craft, cock pit covers, and other marine enclosures. It includes a screen to keep bugs, rodents, and rain out. Boat Vent AERO in Black is made of a flexible yet durable rubber material for easy use.
