Vietnam-era PBR (Patrol Boat, River) IRL.

Vietnam-era PBR (Patrol Boat, River) underway in a canal. These boats were a key part of the U.S. Navy's "Brown Water Navy" operations during the Vietnam War. PBRs were small, fast, rigid-hulled patrol boats, typically 31-32 feet long, designed for shallow-water operations in rivers and deltas. They were constructed from fiberglass and featured a unique "jacuzzi-like" water-jet propulsion system, allowing them to operate in just a few feet of water and be highly maneuverable. The boats carried a crew of four and were armed with various mounted armaments, including machine guns, as seen in the image. Hundreds of these boats were built quickly in the U.S. during the late 1960s, with some seaworthy examples still existing today for historical purposes or tours. 2026 Key Largo #vietnam #keylargo #pbr
