The manually operated Webasto 20 Series sliding marine roof is engineered for installation on a wide range of boats, from center consoles and sport cruisers to custom-built cabins. Built to bring ventilation and natural light to the cabin while maintaining watertight protection, this compact manual sunroof provides a practical upgrade for boat owners who want fresh air and an open feel without running electrical wiring.
Design and construction
The Webasto 20 Series uses an 8mm tempered safety glass panel that is rugged enough for the marine environment while providing clear visibility and daylight through the roof. The opening measures 44.5 by 39.5 inches, large enough to increase airflow and bring daylight into the cabin. The glass panel is mounted in a frame designed to resist water intrusion and to integrate cleanly with deck or roof surfaces on many boat builds.
Operation and features
This sliding roof is manually operated, which eliminates the need for wiring and electrical components. Despite the absence of power operation, the Series 20 offers both tilt and slide functionality, giving users options for different levels of ventilation and shading. A stepless locking system allows the panel to be secured in any position, enabling precise control of airflow and security while underway or at anchor.
Watertight performance and installation
Webasto describes the Series 20 as watertight, with sealing details intended to keep the cabin dry in typical marine conditions. The unit is marketed as easy to install, making it an attractive choice for boatbuilders and owners who want a relatively straightforward retrofit or factory installation. For best results and to preserve watertight integrity, follow the manufacturer’s installation instructions and consider professional installation if you are unsure about deck cutting, sealing, or proper fastening techniques.
Benefits and ideal applications
- Increased ventilation: The tilt and slide options allow for controlled airflow to reduce condensation and improve comfort on warm days.
- Natural light: The large glass panel brightens interior spaces, improving visibility and creating a more open feel belowdeck.
- Simplicity: Manual operation removes the need for wiring and reduces potential electrical maintenance.
- Security and flexibility: The stepless locking system lets users secure the panel in any intermediate position.
Maintenance and care
To keep the sliding roof performing well, periodically inspect seals and hardware for wear, rinse salt and grime from glass and frame, and lubricate moving parts as recommended by the manufacturer. Prompt attention to seal integrity and hardware condition helps maintain watertight performance and extends the life of the fitting.
