Candidates for first-class certificates must have served, while in
possession of a second-class certificate, in vessels of horse-power not
less than that specified in Rule 52, and have been in charge of the
whole of a watch on the main machinery.
First-class candidates must, in addition to service in such vessels,
have performed not less than six months' qualifying service in the
foreign trade, or nine months' similar service in the home trade.
Service performed by engineers in fishing or other vessels which
is not similar to that usually performed by engineers in the mercantile
marine cannot be accepted as qualifying; and the examiner should
in all cases satisfy himself that service performed in such vessels,
when claimed as qualifying for a certificate of competency as engineer,
is of the requisite quality.

SERVICE IN YACHTS.
66. Service performed in yachts, either within or beyond home-trade
limits, may be accepted as equivalent to two-thirds of the same period
of time served in foreign-going vessels, provided that the applicant's
name is entered on the vessel's articles, and that he can prove that
the service claimed was actually performed at sea.
Candidates for second-class certificates may perform the whole of
their service in yachts, but they must have been on regular watch
on main propelling machinery of the requisite horse-power (see Rule 48).
Candidates for first-class certificates must have performed their
service in vessels of horse-power not less than that specified in
Rule 52, and must have been in regular charge of the main propelling
machinery. They must also have served for at least three months
in a qualifying capacity on board a foreign-going ship.
A candidate for a first-class certificate who can prove not less than
twenty-seven months' qualifying service as first engineer, or three
years' qualifying service as second engineer, of a yacht will not be
required to perform this additional service.
