Ch 1, Sec 2, [6.1.2], [6.8] (NEW)

Reference in item [6.1.2] is modified and a new item [6.8] is added as follows:

6 Additional class notations

6.1 General

6.1.1 An additional class notation expresses the classification of additional equipment or specificarrangement, which has been requested by the Interested Party. The assignment of such an additional classnotation is subject to compliance with additional Rule requirements, which are detailed in Part E.

6.1.2 The different additional class notations which may be assigned to a yacht are listed in [6.2] to [6.8] [6.6],according to the category to which they belong.

OMISSIS

6.8 Propulsion plant (HYBRID PROPULSION ())

6.8.1 (1/9/2013)

The additional class notation HYBRID PROPULSION () is assigned to yachts whose propulsion plantconsists of two or more sources of power (i.e. electric motor and internal or external combustion engines)complying with the requirements of Pt E, Ch 1, Sec 7.

The notation is completed, in brackets, with the indication of the functional mode, i.e.:

Parallel mode;

Electric motor and shaft generator mode;

Other modes, to be defined.

The different sources of power may be coupled by clutch or other mechanical or hydraulic couplings tothe gear box or to the shaft lines in a manner such that it delivers the rated power in parallel modeand/or independently.

3 Applicable requirements

3.1

3.1.1(1/9/2013)

For the electric propulsion plant reference is to be made, as applicable, to Pt C, Ch 2. Sec 14, of theRules for the classification of ships. Special consideration may be given under the application of thatsection, to electrical system which may be considered as "auxiliary propulsion system" and which maybe engaged and disengaged without affect in any operative condition the functionality of the primarypropulsion system (i.e.: internal combustion engines).

3.1.2(1/9/2013)

For rotating machines reference is to be made to Pt C, Ch 2. Sec 4, of the Rules for the classificationof ships. In particular, for "auxiliary electrical propulsion system" the same consideration given in [3.1.1]applies.

3.1.3(1/9/2013)

A power management system is to be provided, which in general is to comply with the requirementsgiven in Pt C, Ch 2. Sec 14, [ 4.2] of the Rules for the classification of ships and the relevantautomation system is to comply with the requirements for the assignment of the additional class

notation AUT-UMS (Y)given in Section 1.
