This document is a technical specification and design drawing for a rescue boat, specifically detailing the boat deck construction and equipment layout. The drawing is labeled "KEY PLAN 1-4B" (boat deck) with a scale of 1/8" = 1'-0" and includes comprehensive general notes, a weight control data table, and multiple engineering plans and sections.

The specification encompasses structural requirements including all-welded steel construction unless otherwise noted, with materials meeting Grade A steel specifications. Key technical requirements address hull design at 3.5" above baseline with no frame 126 structure, cleanliness standards for hydraulic systems per ISO 4406 16/14/13, hose quality specifications, and operational pressures of 231 BAR design, 282 BAR testing, and 160 BAR normal operation. The document mandates testing and certification to satisfy applicable specifications for thickness of up to 3/16" and includes detailed provisions for structural modifications, foundation installations, and rescue boat davit replacement. Additional specifications cover painting standards per the owner's requirements, hydraulic hose length sizing based on full motion range, and comprehensive equipment installations including electrical systems, propulsion systems (diesel propelled LPU-44 pypongs), personnel accommodations, and various deck-mounted systems. The detailed hose schedule table identifies specific hose connections throughout the vessel, with Parker as the designated manufacturer and various tube sizes and pressure ratings specified for different system applications.
