1 Not to be given applicants for license as master of towing vessels.

Candidates may use any navigational methods they wish in the solution of problems, provided they are correct in principle. Because of the many different methods of computing a position line it is necessary, in order to obtain uniformity in examinations, to require as an answer either the longitude based on the D. R. latitude as solved by time sight or the longitude of the computed point as obtained by any position line method, eitber with plotting or traverse tables. Computed point is the point at which a perpendicular from the D R. position (for the instant of the sight) intersects the line of position.

(c) (1) Each applicant for an ocean or coastwise deck license, whether original or raise of grade, shall be required to pass practical tests in signalling. The examination in signalling will consist of an examination in the international flag code, Morse flashing, and semaphore. Candidates will be examined in Morse flashing and semaphore in groups where practicable.

(2) Candidates shall be able to read a signal at sight, so far as to name the flags composing the hoist; know the use of the code pennant, numeral and substitute pennants, the meaning of all the single letter signals and the flags used to indicate the quarantine signals; be required to signal some word or words not included in the vocabulary of the code; and have a good knowledge of the distress signals. Candidates will be required to attain a speed of six words a minute in Morse flashing and eight words a minute in semaphore. The average length of a word is to be five letters. Candidates who wish to prove their higher proficiency may request to be tested at a minimum speed of ten words a minute in Morse flashing and twelve words a minute in semaphore. Such candidates, if successful will have the results of their examination reported on their official files.

(3) A candidate for license who fails in signalling, but passes in every other subject, will be considered to have failed the examination and shall be so reported; but he may at any time within the six months following his first attempt be reexamined in signalling only, and if he then passes he will be granted a license.
