This is the live catalog slice for the Maritime & Underwater category. A company appears here only when its primary category matches, and every entry carries a 2024 to 2026 proof-of-life signal recorded with a source link. A full page-unique intro for this category ships in a later polish pass.
How order works. Listings are the full live catalog slice for this primary category, sorted alphabetically by name. This is not a scored quality ranking and there is no paid placement. Operator house products are not catalog entries here; they appear only as a labeled footer bridge. See /transparency.
