Indoor rack storage is desired by boat owners and marinas to protect vessels from weather and extreme temperatures. A major concern is protection of the boats and the storage structure from fire. The nature of the boat construction materials results in a potentially high fire load, and the storage configuration can present significant challenges to activation and water distribution patterns of automatic sprinkler systems.
Specific criterion for the design and installation of fire protection for boats stored on racks inside of buildings is currently lacking. NFPA 303, Fire Protection Standard for Marinas and Boatyards requires that automatic sprinklers systems comply with the provisions of Chapter 12 of NFPA 13, Standard for the Installation of Sprinkler Systems for Group “A” Plastics. However, NFPA 13 does not specifically address indoor rack storage of boats. Fire test data of boats in rack storage is needed to establish more specific requirements for fire control and protection of this type of vessel storage.
