Vico Marine’s Boat Vent 3 is a next-generation boat cover vent, building on the proven success of Boat Vent 2 to help prevent mildew and mold by improving airflow and tenting on covered boats.

Made from highly UV-resistant plastic, it installs easily on almost any boat cover and delivers four key upgrades: (1) 40% increased venting, (2) an overhanging top to reduce moisture entry, (3) a washer with 30 gripping teeth for a stronger hold, and (4) an ergonomic reversible nut for quick, easy installation. When paired with a corresponding support pole (sold separately), it creates proper tenting to shed rain and snow and prevent water pooling.

Boat Vent 3 is available in both black and white, both of which come with a black underside washer that is not visible once installed.

Sold each.
