🔍 Key Concepts
• Properties of Kevlar sailcloth when it’s repeatedly folded or creased
• How polyester (Dacron) sailcloth reacts to moisture and sunlight (UV exposure)
• How traditional canvas sailcloth behaves when stored wet and whether air circulation or covering affects rot
💭 Think About
• For option A, think about what happens to high‑tech fibers like Kevlar when they are sharply creased versus loosely draped. Does folding damage the fibers over time?
• For option B, separate two ideas: resistance to rot from moisture and vulnerability to sunlight (UV). How is Dacron usually cared for on cruising and racing boats?
• For option C, recall what causes rot in natural‑fiber canvas. Does covering a wet sail always make rot worse, or can proper drying and ventilation matter more than simply being covered or uncovered?
✅ Before You Answer
• For each material, match the cause of damage (folding, moisture/rot, UV) with the recommended storage practice (draped, covered, uncovered, ventilated).
• Ask yourself if any statement contains an absolute like "never" that sounds too extreme compared with normal seamanship practice.
• Before choosing D, verify that every single detail in A, B, and C matches what you know about sailcloth care; if even one part is off, D cannot be correct.
