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.

Hatch:
• Outside of lid: 330mm x 330mm (about 13" x 13")
• Cut out in the deck: 260mm x 260mm (about 10-1/4" x 10-1/4")
• Cutout radius: 42.5mm (about 1-11/16")
• Height off of deck: 25mm (about 1")

Lens (not including the gasket):
• Size of Lens: 292mm x 292 mm (about 11-1/2" x 11-1/2") Note: part of this width is hidden under the gasket
• Size of Lens visible on deck: 274mm x 274mm (about 10-7/8" x 10-7/8")
• Distance from center of dog to edge of lens without gasket: 2-5/16" (1/4" greater than MkII)

Please note that these hatches are built in England and made to metric system standard dimensions. All Imperial equivalents are approximate.

1) Lewmar produced the MkI version of their Low Profile hatch beginning sometime in 1999. MkII Lewmar Hatches were produced beginning sometime between July and December of 2000. The easiest way we know to tell the difference for this particular hatch from the MkI and MkII is the handle. MkI has a glued on handle, MkII has a through bolted handle.

2) The production dates quoted for this item are the approximate dates the hatches were produced by Lewmar in the UK. This does not guarantee these were the dates Catalina started installing this version of the hatch during boat production. An earlier hatch design that was already in Catalina's inventory may have been installed on boats built well after production of a later hatch design began in the UK. We have discovered boats built in 2003 equipped with the MkI version of a hatch.

3) One way to identify if your hatch is a MkI or MkII version is to locate a serial number stamped into the hatch lens. This number is melted into the lens, typically under the gasket, visible from the underside of the hatch (see the information below under "Technical Support" Lewmar Low Profile Hatch MkI & MkII Identification). It may be necessary to roll the gasket out of the way a bit in order to see the stamp. The MkI version of the hatch has a number only stamped into the lens, i.e. 39910... The MkII version has a serial number that starts with an "A", i.e. A39910... Note that the "A" was omitted from the MkII version in around 2012. If there is no serial number in the lens, yours is not a Low Profile hatch.

4) Earlier "Coastline" hatches look very similar but have lenses that cannot be replaced by the owner. The Coastline hatch is characterized by a lens that is bonded to the aluminum frame of the lid. It is also lacking the two piece lid frame of the later Low Profile hatches. This split frame has a seam forward and a seam aft where the two halves split. This split feature is what makes it possible to replace the lens and seal in the newer Low Profile hatches. Lewmar Size 10 Low Profile
