2.14.1 At periodical intervals not exceeding 5
years, a lightweight survey shall be carried out on all passenger
craft to verify any changes in lightweight displacement and longitudinal
centre of gravity. The passenger craft shall be re-inclined whenever,
in comparison with the approved stability information, a deviation
from the lightweight displacement exceeding 2%, or a deviation of
the longitudinal centre of gravity exceeding 1% of L is
found or anticipated.
2.14.2 A report of each inclining or lightweight
survey carried out in accordance with paragraph 2.7.1 and of the calculation therefrom of the lightweight condition
particulars shall be submitted to the Administration for approval,
together with a copy for their retention. The approved report shall
be placed on board the craft by the owner in the custody of the master
and shall incorporate such additions and amendments as the Administration
may in any particular case require. The amended lightweight condition
particulars so obtained from time to time shall be used by the master
in substitution for such previously approved particulars when calculating
the craft's stability.
2.14.3 Following any inclining or lightweight
survey, the master shall be supplied with amended stability information
if the Administration so requires. The information so supplied shall
be submitted to the Administration for approval, together with a copy
thereof for their retention, and shall incorporate such additions
and amendments as the Administration may in any particular case require.
