Anchor Scope Calculator
Calculate the recommended anchor rode chain and rope lengths based on water depth, vessel height, and environmental conditions.
Calculated on a vertical height of 0 m (Water Depth 12 + Bow Roller Offset 1.5). The bow roller offset is a critical safety addition as scope is computed from boat-roller to seabed.
Rule-of-Thumb Recommended Minimum Anchor Weight: ~0 lbs (based on general boat sizes with your water depth as proxy).
Keep anchor scopes clear in heavy anchorages and always back down on your hook to verify positive set!
