Which statement about manual firing on a floating vessel is not a condition?

• A. All shells pre-loaded and single break only
• B. Single break only
• C. Shall not exceed 6 inches
• D. Minimum Display Site shall be equal to Electrically Fired Show

Answer: (D)

Manual firing on a floating vessel is governed by safety rules that keep the operation simple and controllable: pre-loading all shells, limiting to a single break per shell, and restricting shell size to manage risk in the maritime environment. These measures help ensure predictable performance and safer handling on deck. The idea that the minimum display site must be equal to what’s required for an electrically fired show doesn’t fit the manual firing context, because electric and manual shows are planned with different control methods and distance requirements. The display area for a manual show isn’t inherently tied to the electric-show distances, so this particular statement isn’t a condition for manual firing on a floating vessel.
