Section 1 General

101. Application

1. Rules for the classification of High Speed and Light Crafts (hereinafter refer to as “this Rules") are to be applied to the hull structure, constructed in steel, aluminium alloy or fibreglass reinforced plastics (FRP) and other materials which are approved by this Society of the light craft, or high speed and light craft, defined in 103.

2. In spite of the craft in

Par 1, cases in which the conditions above are not required, shall be de-

termined at the discretion of this Society.

3. The International Code of Safety for High-Speed Craft, 2000 (hereinafter refer to as "HSC Code"), shall apply to high speed light craft in international operation.

4. Nevertheless regulations of the Rules, crafts constructed in compliance with the related International Conventions are regarded as complying with this Rules. Where the ships have undergone survey ac- cording to relevant governmental regulation and allowed to operate within costal area, the applica- tion of this requirement may be dispensed with.

5. For the securing of vehicles or cargo of ships which are applied to the Ship's Safety Law of Korea and are engaged on domestic sea voyage, it shall be determined at the discretion of this Society. [See Guidance]

102. Classification registry

1. Craft built and surveyed in accordance with the rules of this Society, or with alternative arrange- ments equivalent to the rules, will be assigned a class in the Register Book.

2. All craft classed with the Society are, for continuation of classification, subject to periodical sur- veys, and are to be maintained in conditions in accordance with the rule requirements.

3. The requirements, not mentioned in this chapter, are to be in accordance with Pt 1 of Rules for the Classification of Steel Ships.

103. Definitions

The definitions and symbols of terms are as follows.

(1) Light craft

Light craft means a craft which is complying with the followings.

(A) A craft with a full load displacement of not more than (ton )

(2) High-speed craft

High-speed craft means a craft which complies with the above mentioned in (1), capable of maximum speed whichever is greater than the followings

(A) 25 (kts)

(B) 7.16 ∇ kts or 3.7 ∇ m s

(∇ is in accordance with Pt 3, Ch 1, 103.)

(3) V, L, B and full load displacement () As defined in Pt 3, Ch 1, Sec 1.

(4) Passenger craft

Passenger craft means a craft which carries more than twelve passengers.

(5) Cargo craft

Cargo craft means any high-speed craft other than passenger craft, and which is capable of maintaining the main functions and safety systems of unaffected spaces, after damage in any

one compartment on board.

(6) Cargo spaces

Cargo spaces mean all spaces other than special category spaces and ro-ro spaces used for car- go and trunks to such spaces. For the ships carrying dangerous goods, "cargo spaces" include ro-ro spaces, special category spaces and open deck spaces.

(7) Datum

Datum means a watertight deck or equivalent structure of a non-watertight deck covered by a weathertight structure of adequate strength to maintain the weathertight integrity and fitted with weathertight closing appliances.

(8) Design waterline

Design waterline means the waterline corresponding to the maximum operational weight of the craft with no lift or propulsion machinery active.

(9) Light weight

Lightweight means the displacement of the craft in tonnes without cargo, fuel, lubricating oil,

ballast water, fresh water and feed water in tanks, consumable stores, passengers and crew and their effects.

(10) Ro-Ro craft

Ro-Ro craft means a craft fitted with one or more ro-ro spaces.

(11) Oil fuel unit

Oil fuel unit includes any equipment for the preparation of oil fuel and delivery of oil fuel,

heated or not, to boilers and main engines (including gas turbines) at a pressure of more than

0.18 N mm .

(12) Ro-Ro spaces

Ro-Ro spaces mean spaces not normally subdivided in any way and normally extending to ei- ther a substantial length or the entire length of the craft in which motor vehicles with fuel in their tanks for their own propulsion and/or goods [packaged or in bulk, in or on rail or road cars, vehicles (including road or rail tankers), trailers, containers, pallets, demountable tanks or in or on similar stowage units or other receptacles] can be loaded and unloaded, normally in a horizontal direction.

(13) Open ro-ro spaces

Open ro-ro spaces mean those ro-ro spaces:

(A) to which any passengers carried have access; and

(B) either

(a) are open at both ends

(b) have an opening at one end and are provided with permanent openings distributed in the

side plating or deckhead or from above, having a total area of at least 10 % of the total area of the space sides.

(14) Special category spaces

Special category spaces mean those enclosed ro-ro spaces to which passengers have access. Special category spaces may be accommodated on more than one deck provided that the total overall clear height for vehicles does not exceed 10 m .

(15) Weather deck

Weather deck means a deck which is completely exposed to the weather from above and from at least two sides.

104. Class notations

1. The class notations assigned to the craft classed with this Society are to be in accordance with the requirements in Pt 1, Ch 1, Sec 2 of Rules for the Classification of Steel Ships.

2. In light craft, the additional notation (LC) shall be appended to the class notation, as defined in previous Par. 1.

3. In high speed light craft, the additional notation (HSLC) shall be appended to the class notation, as defined in previous Par. 1.

4. In addition to previous Par. 3, all light craft and high speed light craft shall be given a service restriction notation, defined in Pt 3, Ch 1, 121. (e.g., +ICS - Passenger Ship (HSLC - SA2))
