Your sailing vessel is docked during a storm and is in continuous motion. If a mooring line parts due to vessel motion, it will most likely do so __________.
• Stress concentration points on a line (where bending, sharp turns, or fittings occur) • How a line moves through or around a chock, bitt, or cleat as the vessel surges • The effect of chafing and repeated motion on different parts of a mooring line
• When a vessel surges back and forth in a storm, which part of the line experiences the sharpest bends or rubbing? • Which location along the line is most likely to see both high tension and abrasion at the same time? • Does an evenly stretched straight section of line fail first, or a section that is bent around hardware or fittings?
• Identify where the line passes over or through hardware (chocks, fairleads, bitts) and how that changes the stress on the fibers • Consider where chafing gear is usually placed in heavy weather, and why it is placed there • Think about whether the eye or the part of the line lying straight between vessel and dock has more bending and rubbing under load
