Note 1 to entry: At the option of the owner and subject to the approval of the administration, a lower deck can be designated as a freeboard deck, provided it is a complete and permanent deck continuous in a fore and aft direction at least between the machinery space and peak bulkheads and continuous athwart-ships.

3.20

standard superstructure height

h_std

for vessels up to 75 m load line length: height to be taken as 1,8 m; for vessels over 125 m load line length: height to be taken as 2,3 m; for vessels of intermediate lengths: height to be obtained by linear interpolation

3.21

load line length

L

96 % of the total length on a waterline at 85 % of the least moulded depth measured from the top of the keel, or as the length from the fore side of the stem to the axis of the rudder stock on that waterline, if that be greater

Note 1 to entry: For ships without a rudder stock, the length, L , is taken as 96 % of the waterline at 85 % of the least moulded depth.

3.22

limits in glazed openings

3.23

large yacht

yachts in use for sport or pleasure and commercial operations of L_H higher or equal to 24 m, which is measured according to ISO 8666

3.24

weathertightness

capacity to prevent that, in any sea conditions, water will penetrate into the ship

Note 1 to entry: Meaning of weathertight taken from Annex I, Regulation 3 (12) of International Convention of Load Lines (ICLL). This is interpreted generally as indicating that weathertightness is required from the exterior only, as opposed to watertightness indicating the ability to withstand from both inside and outside (see 3.27).

3.25

watertightness

capacity of an appliance to prevent the passage of water through the structure in any direction under a head of water for which the surrounding structure is designed

3.26

strength

capacity of a structure to maintain full structural integrity under the action of loads

3.27

design loads

external hydrostatic loads according to which glazed openings strength is assessed

3.28

hull

part of the yacht within the envelope of the side shell and decks taken into account for the assignment of freeboard and for stability evaluation

3.29

superstructure

decked structure on the freeboard deck, extending from side to side of the yacht or with side plating not being inboard of the shell plating more than 4 % of the yacht breadth

Note 1 to entry: Definition adapted from Annex I, Regulation 3 (10) of International Convention of Load Lines (ICLL).

3.30

deckhouse

structure enclosing a space that is normally accessible and used for accommodation or service and that does not qualify as a superstructure and that can be positioned on the freeboard deck, and/or the tiers above

3.31

wheelhouse

control position occupied by the officer of the watch

3.32

glass and plastic materials

materials used for glazed openings, as specified in 3.35 to 3.45, and 3.49 and 3.50, with a characteristic failure strength(3.46)

3.33

glass ply

plate made of an inorganic non-crystalline solid exhibiting a glass transition behaviour

3.34

thermally toughened glass

glass where strength increase is obtained by chemical treatment resulting in the introduction of permanent compression stress on both sides of its cross section

3.36

monolithic glass

glazing consisting of one ply of glass

glass pane

ultimate flexural strength at rupture of glass measured, on a statistical basis, in a flexural testing arrangement with a defined method of data reduction taking in account statistical dispersion

3.46

plastic material

ultimate flexural strength at rupture or flexural strength at yield, whichever is lower

Note 1 to entry: The choice between the value at rupture or at yield depends on the mechanical characteristics of the plastic material; as a general indication brittle plastic material will break before yielding while non-brittle plastic material will yield before breaking.
