Product Details

Lewmar's Low Profile Hatches have a low frame section, 8mm acrylic windows, and are available in 7 different sizes, making them a good choice for installation on a variety of boats. The smaller ventilation sizes are suitable for sailboats while the mid and larger hatch sizes work well as foredeck hatches on powerboats or small to mid size yachts respectively.

The hatches are constructed of a two-piece frame with a tough, gray acrylic lens that can be easily replaced simply by unscrewing the frame and inserting a new one. Bonded-on handles under the acrylic lens give a cleaner look on deck and minimize leak paths.

The CE-certified aluminum frame has smooth, rounded edges, inset hinges and rounded corners for snag-resistance. All hatches feature a vent position, flange base and lockable internal and external handles for added security.
