These low profile hatches were used on production boats built after around March of 2000. These can be used as replacements for Coastline hatches of similar size. These hatches are an improvement in that the lenses be more easily replaced.

Known Usage:
• Catalina 34 (2 ea)
• Catalina 42 (3 ea)

This currently available Low Profile hatch pictured eliminated the friction lever used on earlier Coastline hatches in favor of friction hinges. On smaller hatches such as these, Friction Hinges incorporate the friction device within the hinge itself, eliminating the need of the separate Friction Lever. Note in "More images" below that the rise of the deck flange where the gasket seals against the flange is positioned at the inboard edge of the deck flange. Compare to the Coastline flange and you will see it is a defining characteristic. Lewmar eliminated the Coastline version of their hatches in 1999 in favor of the Low Profile design. The Coastline hatch is no longer available but the same size Low Profile hatch can be retrofitted for the same size Coastline hatch in earlier boats.

There may be other instances where this hatch is used. It is also possible that not every boat described above used this hatch. Please use the dimensions above and the photos below to verify which hatch is actually installed on your boat.
