Discover the Sleek Performance of the Lewmar Size 44 Low Profile Hatch

Upgrade your vessel's deck with the Lewmar Size 44 Low Profile Hatch Flange Base, engineered for marine enthusiasts who demand reliability without compromising on style. This hatch stands out in the world of boating hardware for its minimalist 1-inch height, blending seamlessly into cabin tops, cockpits, or foredecks. Ideal for sailboats, yachts, and powerboats, it delivers exceptional ventilation while maintaining a watertight seal against harsh saltwater conditions.

Crafted with marine-grade materials, the smoke grey acrylic window resists yellowing from prolonged UV exposure, ensuring long-term clarity for natural light below deck. At just 10.6 pounds, it's lightweight enough for easy handling during installation or replacement, yet robust for everyday use in demanding offshore adventures.

Why Choose This Low Profile Hatch for Your Boat?

• Streamlined Aesthetics: The ultra-low 1-inch profile minimizes wind resistance and creates a flush, modern look that enhances your boat's lines.
• Superior Ventilation: Self-supporting design holds the hatch open securely at various angles, promoting airflow without additional props.
• Durable Construction: 5/16-inch thick acrylic provides impact resistance, while the 9/16-inch lower frame offers a stable mounting base on flat surfaces.
• Easy Maintenance: Quick-release mechanisms and corrosion-resistant hardware simplify cleaning and inspections, keeping your setup pristine season after season.
• Versatile Applications: Perfect as a V-berth opener, galley vent, or head access point, it fits a range of mid-sized cruisers where space and safety matter.

Boaters often praise its balance of form and function—imagine crisp ocean breezes circulating through your cabin without the bulk of traditional hatches cluttering the horizon.

Detailed Specifications

Precise measurements ensure a perfect fit for your deck cut-out. Here's a breakdown of the core specs:

Professional Installation Tips

Mounting this hatch requires a flat deck surface with no more than +/- 1mm tolerance for optimal sealing. Follow these steps for a secure, leak-free install:

1. Prepare the Surface: Clean and dry the deck thoroughly. Trace the 17 3/8-inch square cut-out with 1 11/16-inch radii using a template.
2. Secure the Hinge: Use M6 (1/4-inch) fasteners at the hinge points for pivot strength.
3. Fasten the Frame: Attach the lower frame with 5mm CSK screws (No.10 UNC or 2 BA) around the perimeter, torquing evenly to avoid warping.
4. Seal Properly: Apply marine sealant under the frame and around fasteners. Test for operation before full cure.
5. Final Check: Cycle the hatch 10-15 times to confirm smooth action and no binding.

Pro tip: For curved decks, consider Lewmar's Ocean or Atlantic series instead. Always wear gloves to protect the acrylic during handling.

Care and Longevity Tips

To maximize lifespan, rinse with fresh water after every sail to remove salt buildup. Polish the smoke grey acrylic annually with a non-abrasive marine cleaner to restore shine. Avoid harsh chemicals that could etch the surface. In storage, keep the hatch slightly ajar to prevent seal compression.
