What is the highest fixed point above the waterline when the mast is up?

Explanation:
The key idea is the air draft—the tallest fixed point above the waterline when the mast is raised. This matters because it tells you the maximum height you can clear under bridges, power lines, and other overhead obstacles. The topmost fixed point on the vessel when the mast is up is the masthead with all permanently mounted gear (lights, antenna, etc.) riding with the mast. For this boat, that fixed top is 9 feet 10 inches above the waterline. That’s why this choice is the best answer: it matches the vessel’s stated height above the water when the mast is up. The other options don’t fit because they either imply a height that’s too short or too tall for the permanent mast-mounted structure. The true fixed point height is 9 feet 10 inches, not the lower figures, and not an exceedingly higher value that would ignore the actual mast-and-fixed-gear height.
