Lewmar Size 22 Low Profile Hatch Flange Base

Discover the Sleek Performance of the Lewmar Size 22 Low Profile Hatch

Engineered for modern boating enthusiasts, the Lewmar Size 22 Low Profile Hatch stands out with its minimalist design that blends seamlessly into deck surfaces. This flange base model excels on powerboats where aerodynamics matter most, minimizing drag while maximizing natural ventilation. On sailboats, its compact footprint fits perfectly in tight spaces like cabins or cockpits, and for mid-sized yachts, it serves as a reliable foredeck access point. What sets it apart is Lewmar's innovative sealing technology, which simplifies acrylic panel swaps without specialized tools—ideal for keeping your vessel looking sharp season after season.

Crafted for durability in harsh marine environments, this hatch complies with CE Category A2 standards, making it safe for exposed deck, coachroof, cockpit, and transom installations. Its self-supporting mechanism holds firm in breezy conditions, eliminating the need for additional struts and reducing maintenance hassles.

Key Features That Elevate Your Boating Experience

• Ultra-Low Profile Design: Just 1 inch high (Z dimension), it hugs the deck for a flush, streamlined appearance that cuts wind resistance and enhances boat aesthetics.
• Smoke Grey Acrylic: Tinted for UV protection and glare reduction, with a robust 3/8-inch thickness to withstand impacts and weathering.
• Self-Supporting Hinge System: Friction-based support keeps the hatch open at any angle, from a gentle breeze to moderate gusts, without gas springs that can fail over time.
• Easy-Access Quick-Action Handles: Smooth operation for effortless opening and securing, even with wet hands or gloves.
• Corrosion-Resistant Materials: Anodized aluminum frame and high-grade seals ensure longevity in saltwater exposure.

At a lightweight 12.8 lbs, it won't burden your boat's structure, and the 9/16-inch lower frame provides a stable mounting base for various deck thicknesses.

Installation Tips from Seasoned Boaters

Installing the Lewmar Size 22 is straightforward with basic tools like a jigsaw, sealant gun, and drill. Start by tracing the 20 3/8-inch cut-out precisely—use the provided template for perfection. Apply marine-grade sealant around the flange, bed the hatch firmly, and secure with stainless screws. The unique sealing system allows for compression without over-tightening, preventing leaks. For best results, angle the hatch slightly forward to shed water efficiently. Pro tip: Test the self-supporting action post-install by simulating wind loads.

Common Pitfalls to Avoid

• Oversized cut-outs leading to misalignment.
• Skipping sealant on uneven decks—use shims if needed.
• Forgetting to protect the smoke grey acrylic during handling.

Maintenance for Long-Lasting Reliability

Keep your hatch performing like new with simple upkeep. Annually inspect seals for wear and lubricate hinges with silicone spray. The acrylic's 3/8-inch thickness resists cracking, but clean gently with freshwater and mild soap to avoid scratches. Replacing the panel? Lewmar's system lets you pop it out in minutes—no adhesives or frame disassembly required. In saltwater zones, rinse thoroughly after every outing to combat corrosion.
