Life floats and buoyant apparatus may be stowed in tiers, one above the other, to a height of not more than __________. (small passenger vessel regulations)

Correct Answer: Option B — 4 feet

46 CFR 180.175 regulates the stowage of life floats and buoyant apparatus to ensure rapid deployment. Stacking these devices in tiers is permitted, but the total height must not exceed 4 feet to prevent obstruction and ensure the crew can quickly access and launch the equipment during emergencies.
