This is the fix. The 360060990 is Lewmar's genuine gray catch block assembly, a spare for the obsolete Ocean, Coastline, and Roll Stop hatch ranges. It comes complete with the block, two pop rivets, and packaging, so you can restore positive hold and a clean seal in about fifteen minutes.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've got an older Lewmar hatch that won't hold its position anymore, or the little block that engages the catch has gone brittle and cracked, this is the part that brings it back to life. The 360060990 is Lewmar's factory catch block assembly in gray, sold as a spare for the obsolete Ocean, Coastline, and Roll Stop hatch ranges. It's a small part. But it's the piece that decides whether your hatch stays where you set it or slams shut on the next wave.\u003c\/p\u003e\n\u003cp\u003eThe catch block is the friction and locking component that lets a Lewmar hatch hold at an open angle and latch down tight when you dog it closed. After years of sun and salt, the original block hardens, chalks, and eventually splits. When that happens the hatch gets sloppy, the seal doesn't pull down evenly, and you start getting drips at the corners. Swapping in a fresh block fixes all of that without touching the frame or the acrylic.\u003c\/p\u003e\n\u003cp\u003eThis one is made for the older, discontinued hatches, so it's a repair part, not an upgrade. It fits the Ocean range across the full size run, from the small 00 up through the big 77, and it covers the Coastline and Roll Stop hatches from the same era. If your hatch has a gray catch block on the frame side and it matches the 5 inch by 7-1\/2 inch footprint, you're in the right place. Not sure which hatch you've got? Measure the clear opening and give us a call, we'll help you confirm before you order.\u003c\/p\u003e\n\u003cp\u003eLewmar ships this as a complete assembly so you're not hunting for hardware. You get the UN0750 gray catch block itself, two 4.8 millimeter AD612SB pop rivets to fasten it, and the header card and self-seal bag it comes packaged in. The swap is straightforward for anyone comfortable with a drill and a rivet gun. Drill out the two old rivets, lift off the tired block, set the new one in place, and pull the new rivets. Fifteen minutes of work on most hatches.\u003c\/p\u003e\n\u003cp\u003eOne thing to know up front: the block is gray only. That's the factory color for these ranges, so it'll match the original hardware on your hatch. Because these hatches are obsolete, genuine Lewmar spares like this one are getting harder to find, so if you run an older boat with Ocean or Coastline hatches, it's not a bad idea to keep one aboard. It's cheap insurance against a hatch that won't seal on a wet passage. And it's the real Lewmar part, not a generic copy, so the fit is exact.\u003c\/p\u003e\n\u003cp\u003eWhere do you find these hatches? All over older cruising sailboats and offshore boats built through the 1990s and 2000s. Ocean and Coastline hatches were Lewmar's mainstream deck hatches for a long stretch, so there are a lot of them still out on the water. If yours still opens and seals but the catch has gotten unreliable, the block is almost always the culprit, not the whole hatch. Replacing a full hatch means cutting sealant, pulling fasteners, and rebedding the frame. Replacing the catch block means two rivets. The math is easy.\u003c\/p\u003e\n\u003cp\u003eA quick tip from the bench: pull the old block off before you order if you can, and check that the gray color and the mounting hole spacing line up. These older ranges shared the same catch block across a wide size span, which is why one part covers everything from a 00 to a 77. Once it's installed, a light wipe with a UV protectant on the exposed plastic a couple times a season will stretch the life of the new block well past the old one.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eGenuine Lewmar 360060990 catch block assembly, an exact-fit factory spare and not a generic copy\u003c\/li\u003e\n  \u003cli\u003eGray finish matches the original hardware on Ocean, Coastline, and Roll Stop hatches\u003c\/li\u003e\n  \u003cli\u003eFits the full Ocean size range, 00 through 77, plus Coastline and Roll Stop hatches from the same era\u003c\/li\u003e\n  \u003cli\u003eIncludes two 4.8 millimeter AD612SB pop rivets so you have the fasteners to mount it\u003c\/li\u003e\n  \u003cli\u003eShips as a complete assembly with the UN0750 catch block, rivets, header card, and self-seal bag\u003c\/li\u003e\n  \u003cli\u003eRestores positive hold and even seal compression on hatches with a worn or cracked block\u003c\/li\u003e\n  \u003cli\u003eSimple two-rivet swap, no frame removal or resealing required\u003c\/li\u003e\n  \u003cli\u003eRepair part for obsolete hatches, keeps an older boat's deck hardware serviceable\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Lewmar reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the catch block actually do?\u003c\/summary\u003e\n    \u003cp\u003eIt's the friction and locking part that lets the hatch hold at an open angle and pull down tight when you dog it closed.
