True or False: Gasoline fuel tanks may not be integrated with hull or boat structure, while diesel tanks may.

The statement is true. Gasoline fuel tanks are required to be isolated from the hull or boat structure due to the volatility and flammability of gasoline. Integrating gasoline fuel tanks with the hull can pose significant safety risks, such as leaks leading to fire or explosion, which is a critical concern in marine environments.

On the other hand, diesel fuel is less volatile than gasoline and is less likely to ignite in the event of a leak. This allows for more flexibility in tank design and placement, including integration within the hull structure, provided that the design adheres to safety standards and regulations set forth by organizations like the American Boat and Yacht Council (ABYC). Therefore, while integrating diesel tanks with the hull structure may be permissible under certain conditions, the same cannot be said for gasoline tanks, which must maintain a degree of separation from the hull to ensure the safety of the vessel and its occupants.
