5.3.1 All skylights should be of efficient weathertight
construction and should be located on or as near to the centreline
of the vessel as practicable.
5.3.2 If they are of the opening type they should
be provided with efficient means whereby they can be secured in the
closed position.
5.3.3 Skylights which are designated for escape
purposes should be openable from either side and in the direction
of escape they are to be openable without a key. All handles on the
inside are to be non-removable. An escape skylight should be readily
identified and easy and safe to use, having due regard to its position.
5.3.4 The skylight glazing material and its method
of securing within the frame should meet an appropriate national or
international standard. Recognised Classification Society rules for
"ships" are considered to meet these requirements. Where a recognised
Classification Society produces alternative rules for "pleasure vessels"
or "yachts", these are considered appropriate for Short Range Yachts.
A minimum of one portable cover for each size of glazed opening
should be provided which can be accessed rapidly and efficiently secured
in the event of a breakage of the skylight.
