This is a technical drawing showing detailed piping diagrams for fresh water and waste systems on a 75' Coast Guard tow boat, produced by Sturgeon Bay Shipbuilding & Dry Dock Co. The drawings consist of multiple cross-sectional views and detailed diagrams showing the fresh water and waste piping configurations throughout different areas of the vessel.

The drawings include multiple sections (labeled A-A through D-D) showing pipe routing, connections, and components, along with specific installation details for deck penetrations, overboard discharges, and pipe supports. General notes indicate requirements for pipe installation, including specifications that all vertical piping runs must be plumb and that no unions shall be installed below floorplates. The drawings contain precise measurements, numbered components, and detailed specifications required for proper installation of the fresh water and waste piping systems. The document appears to be part of a larger set of technical specifications, referenced as sheet 1 and 2 of 2, under Coast Guard contract number 70Z-B993L-A.
