§ 175.05-5 Specific application noted in text.

(a) S: Under the designator "S" shall be included all vessels indicated in column 4 of Table 175.05-1(a) that are not more than 65 feet in length and of

less than 100 gross tons carrying more than six passengers.

(b) L: Under the designator "L" shall be included all vessels indicated in column 4 of Table 175.05-1(a) that are more than 65 feet in length and of less than 100 gross tons which are:

(1) Mechanically propelled vessels of more than 15 gross tons carrying one or more passengers for hire.

(2) Mechanically propelled vessels of not more than 15 gross tons carrying more than six passengers.

(3) Sailing vessels and barges carrying more than six passengers.

(c) Certain portions of this subchapter applicable to only "S" vessels are indicated by the designator "S". Portions applicable to only “L” vessels are indicated by the designator “L”. Those portions of this subchapter applicable to both categories of vessels contain no designator or are designated "S and

L".

(d) At the beginning of the various parts, subparts and sections, a more specific application is generally given for the particular portion of the text involved. This application sets forth the types, sizes, services or vessels to which the text pertains, and in many cases limits the application of the text to vessels contracted for before or after a specific date.

(e) As used in this subchapter the term "vessels contracted for" includes not only contracting for the construction of a vessel, but also contracting for a material alteration to a vessel, contracting for the conversion of a vessel to a passenger vessel, and changing of service or route of a vessel, if such change increases or modifies the general requirements for the vessel or increases the hazards to which it might be subjected.

[CGFR 69-116, 35 FR 6862, Apr. 30, 1970, as amended by CGD 79-165a, 45 FR 64189, Sept. 29, 1980]

$175.05-15 Gross tonnage as a criterion

for requirements.

(a) The regulations in this subchapter, as well as referenced requirements in other subchapters in this chapter, take into account the passenger vessel's size, construction, and equipment,

as well as its intended service on the routes or waters on which it is desired to be operated or navigated, which are indications of the hazards to which such vessel may be subjected. The Commandant's determinations in this respect for a particular passenger vessel are stipulated in a certificate of inspection, which states certain terms and conditions governing such vessels when in operation.

(b) In applying the laws and regulations to passenger vessels, one criterion for invocation of safety standards is the description of passenger vessels by relative size in gross tons. When it is determined by the Commandant that the gross register tonnage for a particular passenger vessel, which is attained by exemptions, reductions, or other devices in the basic gross tonnage formulation, will circumvent or be incompatible with the application of specific safety requirements in the passenger vessel regulations for a vessel of such physical size, the Commandant shall prescribe the regulations to be made applicable to such vessel.

(c) When the Commandant determines that the gross register tonnage is not a valid criterion for the invocation of safety requirements based on relative size, the parties involved will be informed of the determination and of the regulations applicable to such passenger vessel, and before being permitted to operate such vessel, compliance therewith shall be required. Endorsements or notations on the passenger vessel's certificate of inspection may be made as appropriate.

In determining length for the purpose of this chapter it shall be measured from end to end over the deck excluding sheer.

§ 175.10-21 Marine inspector or inspector. This term means any person from the civilian or military branch of the Coast Guard assigned under the superintendence and direction of an Officer in Charge, Marine Inspection, designated for the performance of duties with respect to the enforcement and administration of Title 52 of the Revised Statutes, acts amendatory thereof or supplemental thereto, rules and regulations thereunder.

§ 175.10-23 Non-self-propelled vessel.

Under this designation shall be included all vessels which do not have installed either propulsive machinery or masts, spars and sails.

§ 175.10-25 Ocean.

(a) This term shall be used to describe a route which is more than 20
