This article discusses the fire hazard of motor yachts that are up to 15 meters long. These types of recreational units, in accordance with legal regulations, are not subject to safety inspections. This may lead to negligence that results in a fire within a unit. The construction material most commonly used in the construction of yachts is glass fiber-reinforced plastic, used to produce components such as the hull, deck, and superstructure of motor yachts. The yacht’s equipment, such as furniture and other components, is made, among others, of wood, wood-based materials, or plastics. The results of the flammability tests of such materials presented in this article indicate the need to minimize the risk of fire, the effects of which may be dangerous both to human health and life, as well as the environment
