Estimate nylon (or other) anchor rode elongation under a stretch percent you enter, then see stretched length and an optional effective-scope hint. For rode working length — not snubber OEM sizing and not our dock-line stretch tool.
Enter nylon rode working length, stretch at load (%), and optional depth+freeboard (same units).
Estimate nylon (or other) anchor rode elongation under a stretch percent you enter, then see stretched length and an optional effective-scope hint.
Elongation = rode length × (stretch%/100). Stretched length = length + elongation. Optional scopes: rode÷depth and stretched÷depth. This is rode elasticity under a user %, not snubber length sizing and not dock-line takeoff stretch.
elongation = rode_length × (stretch%/100)
stretched = rode_length + elongation
scope ≈ rode / (depth+freeboard)
Presets are unlabeled as authoritative. Confirm WLL stretch with the rope maker.
Example defaults on this page: depth 20, freeboard 4, tidal rise 2, scope 7:1.
vertical = 20 + 4 + 2 = 26. rode = 26 × 7 = 182 (same units you entered).
That is the arithmetic only — holding ground and rode type are not in the multiply.
This anchor rode nylon stretch page models the arithmetic shown in the formula box only.
Dock-line stretch is for mooring lengths alongside. This page frames nylon rode under anchor load and optional scope change.
No. We do not size snubbers to OEM catalogs. Enter stretch % for the rode segment you care about.
Apply this only to the nylon length that can stretch. Chain elongation is negligible here.
