Collection: Vents

Keeping a boat's cabin, lockers, and fuel system properly ventilated is a matter of both comfort and safety. This selection covers passive and powered options from Attwood Marine, Marinco, Perko, and Sea-Dog, spanning cowl vents, clamshell vents, locker ventilators, and fuel tank vents. Perko offers the widest range here, including stainless steel round locker ventilators in multiple sizes, chrome plated brass and stainless clamshell vents, and gas tank vents with swivel elbows for flexible routing. Marinco adds powered options with the MiniVent 1000 and a Day/Night Solar Vent that runs without shore power or battery draw.

Before buying, confirm the opening size and duct diameter against your existing cutout, since dimensions across this range run from under two inches to four inches. Material matters for longevity: stainless steel handles saltwater exposure better than chrome plated zinc or brass. Gas tank vents are not interchangeable with cabin or locker vents, so match the type to the application carefully. Solar and powered options suit enclosed spaces that need active airflow, while clamshell and cowl designs handle passive deck or through-hull ventilation.
