Question 1815 Deck Safety

The correct answer is D) excessive deadrise. Vessels with excessive deadrise, which is the upward slope of the hull sides, require the use of wale shores when dry docking to provide support and prevent the hull from collapsing inward. Wale shores are wooden or steel supports that are positioned along the hull to counteract the outward pressure caused by the deadrise. The other answer choices are not the primary reasons for using wale shores. A list or excessive trim can be addressed through other means, such as using blocks or wedges. Tumble home, which is the inward slope of the hull sides, does not require the use of wale shores.
