SECOND-CLASS ENGINEER.

(a) Age.

48. A candidate for a second-class engineer’s certificate, whether ordinary or motor, must be not less than twenty-one years of age.

(b) Workshop and Sea Service.

In addition to the workshop service required to be performed by a candidate for a third-class certificate a candidate for a second-class certificate must have served at sea for a period equivalent to eighteen months in foreign-going vessels, as engineer on regular watch on the main propelling machinery of steamships of not less than 66 nominal horse-power, and/or motor-ships of not less than 373 brake horse-power. Time served in the home trade is reckoned as two-thirds of the time similarly served in foreign-going vessels.

For an ordinary certificate at least two-thirds of the required period of service must have been performed in steamships, and for a motor certificate at least two-thirds must have been performed in motor-ships.

The remainder of the service, in each case, may be performed in either steam or motor ships.

(c) Each Candidate must possess a Third-class Certificate.

(1) A candidate for a second-class certificate whether ordinary or motor, must possess a third-class certificate.
