§160.051-1   Scope.

(a) This subpart prescribes requirements for approval by the Coast Guard of A, B, and Coastal Service inflatable liferafts for use only in domestic service. These liferafts must comply with all of the requirements for SOLAS A and SOLAS B liferafts in subpart 160.151 except as specified in this subpart.

(b) This subpart does not apply to any A, B, and Coastal Service inflatable liferaft for use only in domestic service that has been approved by the Coast Guard before November 10, 2011, so long as the liferaft satisfies the annual servicing requirements set forth in 46 CFR 160.151-57.

[USCG-2010-0048, 76 FR 62975, Oct. 11, 2011, as amended by 76 FR 70062, Nov. 10, 2011]

§160.051-3   Definitions.

In this subpart, the term:

A or B liferaft means an inflatable liferaft that meets the requirements prescribed in subpart 160.151 for a SOLAS A or SOLAS B liferaft, respectively, except that the capacity is less than 6 persons and the liferaft cannot contain SOLAS markings.

Coastal Service liferaft means a liferaft that does not meet the all of the requirements prescribed in subpart 160.151 for a SOLAS A or SOLAS B liferaft, but that instead meets the requirements of this subpart and is approved for use on certain uninspected vessels under subchapter C of this chapter.

Commandant means Commandant (CG-ENG-4), Attn: Lifesaving and Fire Safety Division, U.S. Coast Guard Stop 7509, 2703 Martin Luther King Jr. Avenue SE., Washington, DC 20593-7509.

§160.051-7   Design and performance of Coastal Service inflatable liferafts.

To obtain Coast Guard approval, each Coastal Service inflatable liferaft must comply with subpart 160.151, with the following exceptions:

(a) Canopy requirements (IMO LSA Code chapter IV/4.1.1.5, (incorporated by reference, see §160.051-5 of this subpart)). The canopy may—

(1) Be of a type that is furled when the liferaft inflates and that can be set in place by the occupants. A furled canopy must be secured to the buoyancy tubes over 50 percent or more of the liferaft's circumference;

(2) Be of an uninsulated, single-ply design; and

(3) Have an interior of any color.

(b) Viewing port (IMO LSA Code, chapter IV/4.1.1.5.5). The liferaft need not have the viewing port.

(c) Rainwater collection (IMO LSA Code, chapter IV/4.1.1.5.6). The liferaft need not have the means of rainwater collection.

(d) Capacity (IMO LSA Code, chapter IV/4.1.2.1). The carrying capacity must be not less than four persons.

(e) Floor insulation (IMO LSA Code, chapter IV/4.2.2.2). The floor may be uninsulated.

(f) Boarding ramps (IMO LSA Code, chapter IV/4.2.4.1). The liferaft need be provided with boarding ramps only if the combined cross-section diameter of the buoyancy chambers is greater than 500 mm (19.5 in).

(g) Stability (IMO LSA Code, chapter IV/4.2.5). Each Coastal Service inflatable liferaft must either meet the stability criteria in §160.151-17(a) or be fitted with water-containing stability pockets meeting the following requirements:

(1) The total volume of the pockets must be not less than 25 percent of the minimum required volume of the principal buoyancy compartments of the liferaft.

(2) The pockets must be securely attached and evenly distributed around the periphery of the exterior bottom of the liferaft. They may be omitted at the locations of inflation cylinders.

(3) The pockets must be designed to deploy underwater when the liferaft inflates. If weights are used for this purpose, they must be of corrosion-resistant material.

(h) Lamp (IMO LSA Code, chapter IV/4.1.3.4). The liferaft need not have the manually controlled interior lamp.

(i) Markings (IMO LSA Code, chapter IV/4.2.3.6). The words “COASTAL SERVICE” must appear on the container, and the type of equipment pack must be identified as “Coastal Service”. No “SOLAS” markings may appear on the container.
