6.1.4.1 Every free-fall launching appliance shall
comply with the applicable requirements of paragraph 6.1.1 and, in addition, shall comply with the
requirements of this paragraph.
6.1.4.2 The launching appliance shall be designed
and installed so that it and the lifeboat it serves operate as a system
to protect the occupants from harmful acceleration forces as required
by paragraph 4.7.5, and to ensure effective
clearing of the ship as required by paragraphs 4.7.3.1
and 4.7.3.2.
6.1.4.3 The launching appliance shall be constructed
so as to prevent sparking and incendiary friction during the launching
of the lifeboat.
6.1.4.4 The launching appliance shall be designed
and arranged so that in its ready to launch position, the distance
from the lowest point on the lifeboat it serves to the water surface
with the ship in its lightest seagoing condition does not exceed the
lifeboat's free-fall certification height, taking into consideration
the requirements of paragraph 4.7.3.
6.1.4.5 The launching appliance shall be arranged
so as to preclude accidental release of the lifeboat in its unattended
stowed position. If the means provided to secure the lifeboat cannot
be released from inside the lifeboat, it shall be so arranged as to
preclude boarding the lifeboat without first releasing it.
6.1.4.6 The release mechanism shall be arranged
so that at least two independent actions from inside the lifeboat
are required in order to launch the lifeboat.
6.1.4.7 Each launching appliance shall be provided
with a secondary means to launch the lifeboat by falls. Such means
shall comply with the requirements of paragraph 6.1.1 (except 6.1.1.3) and paragraph 6.1.2 (except 6.1.2.6). It must be capable
of launching the lifeboat against unfavourable conditions of trim
of up to only 2° and list of up to only 5° either way and
it need not comply with the speed requirements of paragraphs 6.1.2.8 and 6.1.2.9. If the secondary launching
appliance is not dependent on gravity, stored mechanical power or
other manual means, the launching appliance shall be connected both
to the ship's main and emergency power supplies.
6.1.4.8 The secondary means of launching shall
be equipped with at least a single off-load capability to release
the lifeboat.
