1 This chapter applies to high-speed craft constructed
on or after 1 January 1996, as follows:
-
.1 passenger craft which do not proceed in the
course of their voyage more than 4 h at operational speed from a place
of refuge when fully laden; and
-
.2 cargo craft of 500 gross tonnage and upwards
which do not proceed in course of their voyage more than 8 h at operational
speed from a place of refuge when fully laden.
2 Any craft, irrespective of the date of construction,
which undergoes repairs, alterations, modifications and outfitting
related thereto shall continue to comply with at least the requirements
previously applicable to the craft. Such a craft, if constructed before
1 July 2002, shall, as a rule, comply with the requirements for a
craft constructed on or after that date to at least the same extent
as it did before undergoing such repairs, alterations, modifications
or outfitting. Repairs, alterations and modifications of a major character,
and outfitting related thereto, shall meet the requirements for a
craft constructed on or after 1 July 2002 in so far as the Administration
deems reasonable and practicable.
