Boat Anchors

Select an anchor type based on bottom conditions (fluke or Danforth for sand/mud, plow for mixed bottoms, claw for soft to rocky bottoms); match anchor size to your boat's length and displacement using manufacturer sizing charts and err toward a larger size if you frequently face strong winds or currents

Use a scope (ratio of rode length to water depth) of 5:1 to 7:1 in normal conditions; include enough chain to reach the seabed and provide catenary (typically 10–30 feet of chain) plus rope to achieve the desired scope, increasing scope in severe conditions

Anchors are typically made from galvanized steel, stainless steel, or aluminum: galvanized steel is durable and cost-effective, stainless resists corrosion better but costs more, and aluminum is lightweight for small boats; all require rinsing after saltwater use and periodic inspection for corrosion or damage

Carrying a primary anchor sized to your boat and at least one smaller backup or a different type is recommended because bottom conditions and unexpected weather can reduce holding power, and having a backup provides redundancy if the main anchor fails to set or is lost

Rinse anchors, chain, and rope with fresh water after use in saltwater, remove mud and marine growth, inspect shackles and swivels for wear, lubricate moving parts with marine-grade lubricant, and store dry in a well-ventilated anchor locker to prevent corrosion and odor

Anchors for small recreational boats commonly range from under $50 for basic lightweight models to several hundred dollars for larger or specialty anchors; average prices for widely used anchors in this category are around $80, but choice should be based on size and type rather than price alone

After dropping the anchor, reverse the boat slowly to load the rode and feel for resistance, check landmarks or electronics (GPS anchor alarm) for drift, and visually inspect rode tension and angle; if the boat drifts or the rode runs out, reset with more scope or a different location
