Lewmar Size 60 Low Profile Hatch Flange Base Product Description
Discover the Sleek Performance of the Lewmar Size 60 Low Profile Hatch
Engineered for modern boats where every inch counts, this Lewmar Size 60 low profile hatch flange base delivers unobtrusive access and ventilation without compromising on strength or style. Ideal for deck installations on sailboats, yachts, or power vessels, its minimalist 1-inch height hugs the surface, reducing drag and enhancing aesthetics. The smoke grey acrylic pane cuts glare while offering crystal-clear visibility, and the self-supporting design means no extra stays or props needed for everyday use.
Crafted with a robust aluminum frame, it withstands harsh marine environments—salt spray, UV exposure, and constant flexing from waves. The 180-degree opening provides generous vertical access for storage below decks, making it perfect for cabins, heads, or lazarettes. Secure it with the built-in lock for peace of mind at anchor or underway.

These measurements ensure a factory-like install—square and square, with radiused corners that match curved deck molds common on performance hulls.
Effortless Installation Tips from the Field
Prep your deck for success: aim for a flat surface within +/- 1mm tolerance to avoid binding or leaks. At the hinge, secure with M6 (1/4-inch) fasteners for pivot strength. For the lower frame, opt for 5mm countersunk No.10 UNC or 2 BA screws—pre-drill to prevent gelcoat cracks. Seal generously with marine-grade polyurethane around the flange for watertight integrity that lasts seasons.
Pro tip: Dry-fit first, then bed in place. The low profile flange distributes load evenly, minimizing stress on thin cored decks. Most installs take under an hour with basic tools, but always torque fasteners to spec to handle slamming in chop.
Why Boaters Trust Lewmar Low Profile Hatches
- Ultra-Low Drag: At just 1 inch high, it slices through wind better than bulkier vents—great for racing or long passages.
- Glare-Free Viewing: Smoke grey tint blocks harsh sunlight without darkening your view of gauges or charts below.
- Lockable Security: Integrated lock deters casual theft in crowded marinas.
- Heavy-Duty Acrylic: 5/16-inch thick plexiglass shrugs off hailstones and deck pounds.
- Versatile Storage Access: Full 180-degree swing reveals ample space for gear, lines, or spares.
Beyond specs, this hatch shines in real-world abuse: cockpit washes, tropical storms, and years of daily openings. Pair it with Lewmar's quick-action handles for one-handed operation, even with wet hands.
Keep It Performing Like New
Rinse with fresh water after every sail to flush salt. Lubricate hinges annually with marine grease—PTFE-based for low friction. Inspect seals yearly; replace if they harden. Acrylic cleans easily with soft cloth and ammonia-free soap—avoid abrasives to preserve clarity. In storage, prop slightly open to prevent mildew in the locker below.
