What this video covers
Replacing stainless steel sheathed lifelines with Dyneema on the 38-ft vessel Britaly involves removing existing turnbuckles and threading the new line through stanchion apertures.1:09 To prevent chafe, all stanchion holes must be smoothed with 80-grit sandpaper to remove metal burrs.2:38 The installation process uses a 12-strand eye splice, with the tail buried and tapered to maintain strength and prevent fiber fatigue at the transition point.8:34 A stainless steel thimble is inserted into the cockpit-end eye to reduce friction during lashing.14:07 The lashing itself is secured using a figure-eight pattern and half-hitches, which provides sufficient tension without requiring turnbuckles or low-friction rings.20:53 Because Dyneema is susceptible to heat damage, heat shrink should be avoided; sacrificial whipping with smaller-diameter line serves as a better chafe guard against stanchions.3:15 The material is lightweight, cost-effective, and user-friendly for DIY installation. Dyneema lifelines require periodic re-tensioning as the material settles and stretches after initial installation.21:15
