🔍 Key Concepts
• Uninspected Towing Vessels (UTV) fire protection requirements for vessels over 300 GT vs under 300 GT in 46 CFR Subchapter C
• Definitions and size ratings of semi-portable fire extinguishing systems (e.g., 140-B, 150-B, 160-B) in 46 CFR Part 25
• Special requirements that apply to UTVs whose construction was contracted for after August 27, 2003
💭 Think About
• How does the vessel’s gross tonnage (GRT) and its status as an uninspected towing vessel affect which fire system rating is required?
• What changes in fire protection requirements were introduced for towing vessels constructed after August 27, 2003, and where are those spelled out?
• Among 140-B, 150-B, and 160-B systems, which rating is specifically tied in the regulations to towing vessels of this size and construction date?
✅ Before You Answer
• Look up the table for fire-extinguishing equipment requirements for uninspected towing vessels of about 300 GRT in 46 CFR 25.30 or the applicable fire protection section for UTVs.
• Confirm the exact rating designation (e.g., 140-B, 150-B, 160-B) that the CFR text uses for semi-portable systems on towing vessels in this tonnage and date category.
• Verify whether the rule for post–August 27, 2003 construction points to a specific B-rated semi-portable size, and ensure that number appears clearly in the regulation.
