108. Definitions

For the purposes of this Guidance, the following definitions are to apply:

1. Recreational craft

Any craft of any type intended for sports and leisure purposes of hull length(ÄĂ) from 2.5 m to 24 m, measured according to the 5.2.2 in KS V ISO 8666, regardless of the means of propulsion.

2. Propulsion engine

Any spark or compression ignition, internal combustion engine used for propulsion purposes, including two-stroke and four-stroke inboard, stern-drive with or without integral exhaust and outboard engines.

3. Major engine modification

The modification of an engine which :

(1) could potentially cause the engine to exceed the emission limits set out in Ch 8 excluding rou- tine replacement of engine components that do not alter the emission characteristics, or

(2) increases the rated power of the engine by more than 15 %.

4. Major craft conversion

A conversion of a craft which:

(1) changes the means of propulsion of the craft,

(2) involves a major engine modification, or

(3) alters the craft to such an extent that it is considered a new craft.

5. Means of propulsion

The mechanical method by which the craft is driven, in particular marine propellers or water-jet mechanical drive systems.

6. Engine family

The manufacturer's grouping of engines which, through exhaust emission characteristics and which comply with Guidance.

their design, are expected to have similar the exhaust emissions requirements of this

7. Craft identification number

Unique series of numerals, letters and a hyphen, permanently affixed to a craft hull.

8. Builder's plate

Label or plate to display basic user information related to the recreational craft.

9. Graphical symbol

Visually perceptible figure with a particular meaning used to transmit information independently of language.

10. Loaded displacement mass ŶÄǼÆ

Mass of the boat in the loaded displacement condition, including all appendages.

11. Mass of light craft ŶÄÆÆ

Mass of the craft in light craft condition, as defined in KS V ISO 8666

12. Nominal sail area (AÅ)

Nominal projected profile area of sails, as defined in KS V ISO 8666 (mË)

13. Sailing craft

Craft for which the primary means of propulsion is by wind power, having AÅ ≥ ŊĦŊĒFŶÄǼÆ FË ĤĖ

14. Non-sailing craft

Craft for which the primary means of propulsion is other than by wind power, having

15. Fully decked craft

Craft in which the horizontal projection of the sheerline area comprises any combination of

(1) watertight deck and superstructure, and/or

(2) quick-draining recesses complying with Ch 6, Sec 3, and/or

(3) watertight recesses complying with Ch 6, Sec 3 with a combined volume of less than

ÄĂAĂÁÀĤĖŊ, all closing appliances being watertight in accordance with Ch 6, Sec 2.

16. Partially decked craft

Craft in which at least two-thirds of the horizontal projection of the sheerline area is equipped with decking, cabins, shelters or rigid covers which are watertight according to Ch 6, Sec 2 and de- signed to shed water overboard, in which area all that within ÄĂĤĖ from the bow and also the area 100 mm inboard from the periphery of the craft are included.

17. Dimensions, areas and angles

(1) length of hull (ÄĂ)

length of the hull according to KS V ISO 8666, (m)

(2) length waterline (ÄBÄ)

waterline length measured in accordance with KS V ISO 8666 when the craft is upright in

calm water, in the appropriate loading condition and at design trim, (m)

(3) beam of hull (AĂ)

maximum beam of the hull according

- For catamaran and trimaran crafts,

outer hulls.

(4) beam waterline (ABÄ)

to KS V ISO 8666, (m)

AĂ shall be measured as the maximum beam across the

greatest beam measured according to KS V ISO 8666 at the waterline, which for multihull

crafts is the sum of the maximum waterline beams of all hulls, the craft being upright, in the appropriate loading condition and at design trim, (m)

(5) freeboard amidships (ÁÀ)

distance of the sheerline or deck above the waterline at ÄĂĤË according to KS V ISO 8666, the craft being upright, in the appropriate loading condition and at design trim, (m)
