S&S defines a System Schematic as a line diagram showing the interconnection and relationship of elements to show the philosophy and operation of the system, but does not show the physical elements. It is not intended as an installation diagram or as a complete System Design.

Construction Support Phase
S&S will inspect the quality of the work for compliance with the best applicable standards and the Client agrees that S&S shall inspect the work at reasonable intervals and be guided by S&S recommendations with regard to the quality of workmanship, materials and fittings to include:
• Consultation with the builder and review of Builder’s, and its Subcontractors’, detailed construction and shop plans with respect to aesthetics, function, performance, strength and safety.
• Periodic visits to the Builder's yard to observe and inspect the progress and quality of the work for compliance with the plans, specifications and build schedule.
• Sea Trials of the completed yacht including review of compliance to plans and specification.
• Flotation and Inclining Measurements and Analysis
• Trim and Stability Booklet
• Performance Analysis
