§ 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.
( j ) *Drop test.* The drop test required under paragraph 1/5.1 of IMO Revised recommendation on testing (incorporated by reference, see § 160.051-5 of this subpart) and 160.151-27(a) may be from a lesser height, if that height is the maximum height of stowage marked on the container.
( k ) *Loading and seating test.* For the loading and seating test required under paragraph 1/5.7 of IMO Revised recommendation on testing and § 160.151-27(a), the loaded freeboard of the liferaft must be not less than 200 mm (8 in.).
( l ) *Cold-inflation test.* The cold-inflation test required under paragraph 1/5.17.3.3.2 of IMO Revised recommendation on testing and § 160.151-27(a) must be conducted at a test temperature of −18 °C (0 °F).
