Section 5 Information required

5.1.1 The categories and lists of information required are given in Pt 3, Ch 1, 5.2 Submission of plans and data.

5.1.2 Plans are generally to be submitted in triplicate, but one copy only is necessary for supporting documents and calculations.

5.1.3 Plans are to contain all necessary information to fully define the structure, including construction details, equipment and systems as appropriate.

5.1.4 Additional requirements for individual craft types are given in subsequent Chapters.

5.2.1 Plans and data required to be submitted are indicated in Pt 6 Hull Construction in Steel, Pt 7 Hull Construction in Aluminium and Pt 8 Hull Construction in Composite for steel, aluminium alloy and composite construction respectively, as appropriate.

5.2.2 Where an *IWS (In-Water Survey) notation is to be assigned, see Pt 1, Ch 2, 3.8 Other hull notations 3.8.2, plans and information covering the following items are to be submitted:

• Details showing how rudder pintle and bush clearances are to be measured and how the security of the pintles in their sockets are to be verified with the craft afloat.
• Details showing how stern bush clearances are to be measured with the craft afloat.
• Details of high resistance paint, for information only.

5.3.1 Where a craft is a standard design produced in several versions, the plans and data are to clearly define the differences between each version.

5.3.2 Where the craft is a Builder's standard design to be built from previously approved plans and data, a schedule of applicable plans, etc. is to accompany the Request for Survey. Plans of any proposed modifications and changes to the previously approved plans are to be submitted for approval prior to the commencement of any work.

5.3.3 Plan approval of standard designs is only valid so long as no applicable Rule changes take place. When the Rules are amended, the plans for standard types are to be submitted for re-approval.

5.4.1 To facilitate the ordering of materials for repairs, plans are to be carried in the craft indicating the disposition and grades (other than Grade A) of hull structural steel, the extent and location of higher tensile steel together with details of specification and mechanical properties, and any recommendations for welding, working and treatment of these steels.

5.4.2 Similar information is to be provided when aluminium alloy, fibre composite or other materials are used in the hull construction.

5.4.3 A copy of the final Loading Manual, (where applicable) when approved, and details of the loadings applicable to approved decks, hatch covers and inner bottom are to be placed on board the craft.

5.4.4 Details of any corrosion control system fitted are to be placed on board the craft.

5.4.5 Copies of main scantling plans are to be placed on board.

5.4.6 Electrical cables schedule of watertight penetrations (e.g. cable transit seal systems register).

5.4.7 Where an *IWS (In-water Survey) notation is to be assigned, approved plans and information covering the items detailed in Pt 3, Ch 1, 5.2 Submission of plans and data 5.2.2 are to be placed on board.

5.5.1 For information and plans required, see Pt 17 Fire Protection, Detection and Extinction.
