An anchor's job is simple: keep your boat where you put it. But the best anchor for your boat depends on two things — the bottom you anchor over (sand, mud, grass, or rock) and the size and windage of your hull. Most boaters are best served by a fluke or claw anchor sized to their boat length.

These three covers the most common needs — from lightweight aluminum flukes with exceptional holding-to-weight, to a do-anything claw. Pair any of them with the right rode (chain plus line) and a few dock lines and fenders.
Proven models that balance price, durability, and real-world performance. Prices change often — tap through for the current price.
A Bruce-style claw that sets quickly across sand, mud, and rock and resets well when the wind shifts. Forgiving and low-fuss — the anchor most owners reach for first.
A precision aluminum fluke anchor that's a fraction of the weight of steel for the same holding power — easy to stow and deploy. Excellent in sand and soft mud.
A classic galvanized Danforth-style fluke at a friendly price. Flat profile stows easily in an anchor locker and bites hard in sand and mud — a smart first anchor.
Manufacturers publish a boat-length and wind rating for each anchor size. Choose by your boat's length and displacement, then go one size up if you anchor in exposed water or strong wind. An undersized anchor that drags is worse than no anchor.
Fluke (Danforth-style) anchors hold best in sand and mud and have superb holding-to-weight. Claw anchors set fast and handle mixed bottoms including rock and grass. If you anchor in one type of bottom often, optimize for it.
Anchor rode is the line and chain between boat and anchor. A length of chain at the anchor helps it lie flat and set. Let out a scope of about 7:1 (seven feet of rode per foot of water depth) for a secure overnight hold.
Two to four dock lines sized to your boat, plus fenders to protect the hull, and a couple of cleats make tying up painless. A foldable boat hook earns its keep at the ramp and the slip.
Holding power comes from scope, not just anchor weight. Even a perfectly sized anchor will drag on too little rode — carry enough line to pay out at least 7:1 in the deepest water you anchor in.
Go by the manufacturer's boat-length and wind rating rather than a single weight number. As a rough guide, many 18–22 ft boats are well served by an 8–14 lb fluke or claw, sized up for windy, exposed anchorages.
Fluke anchors give the most holding power for their weight in sand and mud. Claw anchors set faster and handle mixed and rocky bottoms more reliably. Many boaters carry one of each for different conditions.
Plan for a scope of about 7:1. For anchoring in up to 20 feet of water you'd want roughly 140 feet of rode, ideally with a few feet of chain at the anchor to help it set and to resist chafe.
A short length of chain (often 4–6 feet for small boats) helps the anchor lie flat so the flukes dig in, adds weight low in the system, and protects the line from abrasion on the bottom.
