Hatch Lens Improved, Bomar Trapezoidal,
17" Centers

Part #: Z2471
Replacement smoked acrylic lens only for your existing Bomar NIBO aluminum framed trapezoidal hatch.

Bomar builds haches with both 1/4" and 3/8" thick lenses. The frame of the lid surrounding the lens differs to accommodate the lens thickness. Many early boats were built with hatches that used 1/4" thick lenses. These have proven to be subject to failure when the crew stands on a hatch weakened by age.
We know that Catalina Yachts purchased hatches of both types, but no record exists indicating which hatch was used on which boat. And you can't tell which you have until you start disassembling the hatch.

Catalina Direct has solved both strength and fit issues with one custom made replacement lens. Our 3/8" thick lens is beveled at the top outside edge to fit properly into a frame designed for 1/4" thick polycarbonate. And it benefits from the strength provided by 3/8" material. If you disassemble your hatch and discover Catalina used a hatch with a 3/8" thick lens on your boat, simply turn our lens over. The outside dimensions are the same regardless of lens thickness. The small void left by the bevel at the bottom corner will fill with sealant. The width of the frame flange will support the lens properly and the top of the lens will fit flush with the top of the frame. As an added bonus, Catalina Direct's custom upgrade costs less than Bomar's 1/4" lens!

Please inspect the gasket currently on your forward hatch. It may need to be replaced. See gasket suggested below.

Known usage for this lens with holes for dogs on 17" centers:

We believe this wide hole center spacing was used on early boats that didn't typically have hatch adjusters. Customers with boats built from 1986 through early 1989 report these are the correct lenses. Later boats used lenses with holes for dogs that are placed closer together.
