Product Details

Lewmar Ocean Hatches are found on thousands of sailboats around the world. Their rugged construction makes them suitable for use on the largest offshore yachts. Approved by Lloyd's, these heavy duty hatches have the features, reliability, safety, and strength required for offshore sailing vessels.

Available in both flat base and flanged base designs, Ocean hatches have a two piece aluminum frame with bonded gray acrylic lens and external hinges. If cracked or scratched, replacement is easy. Simply unscrew and insert a new lens. Hatch frames have smooth, rounded edges, with rounded corners to minimize snags. Design reduces the chances of water entering the boat when the hatch is opened.
