Question 1713Deck Safety70% to pass
The two factors which make underwater hull repair difficult are accessibility and the _______________.
AI Explanation
The correct answer is B) pressure exerted by the water.
Underwater hull repair is difficult due to the pressure exerted by the water on the repair site. The deeper the hull is submerged, the greater the water pressure, making it challenging to effectively apply sealants, patch materials, or perform welding repairs. The high water pressure can prevent proper adhesion of repair materials and make it difficult to access the damaged area. In contrast, the other options, such as tool availability, hull shape, and progressive flooding, while relevant factors, are not the primary reasons that make underwater hull repair difficult.
