Sea-Dog Low-Profile PVC Cowl Vent with Snap-On Deck Plate – Large
A larger-format, low-profile cowl vent designed for air intake and cabin ventilation on boats where deck clearance is limited. The low-profile design keeps the vent close to the deck to avoid fouling lines or restricting crew movement, while the larger size moves more air than the smaller versions — making it a practical upgrade for bigger cabins or higher-ventilation-demand spaces. Includes a snap-on deck plate and cover for sealing in rough weather.
Key Features
- Large low-profile cowl vent — more airflow capacity than smaller low-profile models
- Designed for air intake or cabin ventilation, especially effective with a dorade box
- Suitable for bilge ventilation with or without a blower
- Low-profile design — ideal where a taller vent would foul lines or restrict crew movement
- Includes snap-on deck plate and weather cover for rough conditions
- Constructed from UV-resistant dip-moulded PVC for long-term durability
- Avoid contact with acetone or strong solvents
Parts Desk Insights
Best use case: Choose this larger low-profile vent when you need more airflow than the smaller models provide but still can’t use a standard upright cowl due to deck clearance constraints. It’s well suited to larger cabins, engine compartments, or any space where ventilation demand is higher. For smaller low-profile options, see the Sea-Dog Low-Profile PVC Cowl Vent or the companion size. If deck clearance isn’t a concern and you want maximum airflow, see the Sea-Dog Standard PVC Cowl Vent. To service the snap-on deck plate, see the Deck Plate Key or the Universal Deck Plate Key.
