This document is a structural schematic and engineering drawing for a rescue boat and associated support structures. It is prepared by Licensed Professional Engineer Andrew Harvey Thompson (Mechanical) for the State of California and includes detailed architectural plans, cross-sections, and elevation views for a vessel modification project.

The drawings show comprehensive structural details for a rescue boat design, including general notes requiring ASTM steel construction standards, welding and inspection compliance, frame spacing specifications, and multiple material options for structural components. Key specifications include deck construction, structural removals and modifications, foundation installation requirements, and support structure design. The material list indicates various steel elements with dimensions ranging from 3.5 to 5.5 inches for structural members, with ASTM A36 designation and OSS (Open Structural Section) classifications. Multiple plan views (Plan 1-3B through Plan 5-4A) provide detailed layouts of deck structures, while elevation sections and detail drawings illustrate beam configurations, connection points, and clearances. Reference callouts throughout the drawings direct to related design plans, including specific foundation dimension notes and structural modification details. The drawing set includes weight control data and references rescue boat davit installation plans, suggesting this is part of a maritime vessel or offshore platform upgrade project requiring compliance with California engineering standards.
