Anodized Aluminum Boat Porthole Window Marine Hatch
This 14 inch by 6 inch porthole uses a solid anodized aluminum frame for maximum corrosion resistance, ideal for saltwater environments. The grey acrylic window provides clarity while maintaining safety. A 180-degree opening with a secure locking mechanism enhances ventilation and provides an emergency exit option. Best for: boat owners needing a rugged, easy-to-operate hatch on sailboats, powerboats, or RV installations. Caution: ensure deck cutout matches the 14″ x 6″ footprint and verify hinge clearance for full 180-degree opening.
Amarine Made Rectangle Opening Portlight 15-3/4″ x 7-7/8″
These 15-3/4″ by 7-7/8″ rectangular portlights feature 4 mm tempered glass, ABS anti-aging, and anti-UV properties with casted and polished 316 stainless steel accessories. Best for: replacements or upgrades on larger hull openings where a bright, framed window is desired. Choose this if you want a proven, rectangular profile with strong UV resistance. Limitation: some installations may require precise cutouts to fit the 15-3/4″ x 7-7/8″ frame.
Amarine Made Rectangle Opening Portlight (Black)
The black variant matches contemporary boat interiors while offering the same 4 mm tempered glass, anti-aging, and anti-UV properties with robust 316 stainless steel hardware. Best for: boats that demand a darker window frame to reduce glare or to blend with black deck fittings. Limitation: darker frames may show scratches more readily than lighter finishes.
HECASA Porthole Screen for Sea Ray
This porthole screen is designed for Sea Ray models and other compatible cruisers. It uses sturdy ABS plastic in a black finish and provides high adaptability for various models. Best for: retrofit projects where a reliable screen to allow airflow and light is required without full window replacement. Caution: verify model compatibility for your specific Sea Ray year and model to ensure a proper fit.
Amarine Made 10″ Round Porthole Window
This round 10″ porthole provides a compact option with ABS construction and tempered glass. Best for: small boats, cabins, and tight spaces where a round hatch is preferable for aesthetics or space constraints. Limitation: smaller clear opening reduces ventilation potential compared with larger rectangular portlights.
Amarine Made 22.5 x 22.5 in Porthole Window
A larger option, this 22.5 by 22.5 inch porthole uses anodized aluminum with a 10 mm thick acrylic lid. It’s designed for versatile compatibility across boats, yachts, and RVs. Best for: vessels needing substantial light and a generous hatch for circulation and emergency exit. Caution: ensure deck thickness accommodates the 22.5 inch frame and that the lid’s weight is manageable for your installation.
Buying Guide: Key Purchase Considerations
- Material durability: Look for marine-grade aluminum or ABS with UV protection and tempered glass to resist corrosion, weathering, and impact.
- Opening mechanism: Decide between full 180-degree openings for maximum ventilation or smaller openings for safety and moisture control.
- Size and fit: Confirm deck cutouts match the window dimensions; measure interior clearance to ensure full operation without interference.
- Glass and lid: Tempered or acrylic windows balance weight and safety; thicker lids and robust hinges improve long-term performance.
- Finish options: White, black, or gray frames affect aesthetics and glare; pick a finish that complements your vessel’s exterior and interior.
- Compatibility: Some units are designed for specific models or brands; verify compatibility if retrofitting or replacing existing portlights.
