[font "Comic Sans MS"][black][size 3]A machanical anchor such a a danforth style anchor is easier on your back because it weight a third of a 20 lb anchor. I have a Danforth on the front of my boat and that anchor has held in some very rough water. There is nothing wrong with a Danforth. They are the standard that other anchors are rated against.[/size][/black][/font]

[font "Comic Sans MS"][black][size 3]you will never see an navy style anchor on a boat that's serious about staying in place especially in rough weather. weight alone will not do it. Most anchors are used with an anchor chain and the proper diameter nylon twist rope. Contrary to popular belief, yellow poly rope, cotton clothes line rope, and parachute cord are not suitable substitutes for anchoring applications.[/size][/black][/font]

Anchor types
Kedge. A traditional anchor with relatively small flukes perpendicular to the stock and connected by a shank. It is commonly used to warp a boat from one berth to another or to haul off when grounded. Its large size and heavy weight relative to its holding power have caused this anchor to fall from favor. Kedge anchors are difficult to stow, but they're great for weedy bottoms. Brands: Fisherman, Yachtsman, Luke.
Pivoting twin fluke. A lightweight anchor, made of steel or aluminum plate and bar stock, with a high holding power-to-weight ratio. These anchors are easy to lift, throw, and retrieve. They are ideal for sand, mud, and clay bottoms. The pivoting flukes dig in easily, often disappearing into the bottom. They are not as effective on rocks or in grass, and they tend to pick up debris easily. Brands: Danforth, Fortress, Hooker.
Plow. An anchor with blades that resemble a farmer's plow. A traditional anchor for cruisers, the plow is designed so it rights itself when deployed, causing the blade to plow into the bottom. Plows perform well in grassy bottoms and also work in sand and mud, but they tend to be twice as heavy as pivoting-fluke types for the same holding power. This makes for a moderately heavy anchor, but one that stows easily in a bow roller. Brands: CQR, Delta, Spade.
Tripoint. Very popular with cruisers, the tripoint has no moving parts to get jammed or that give, works with a variety of bottoms, and easily plows into softer surfaces. It features three round-edged flukes that curl out from the dogleg shank. It was invented in Scotland to secure floating oil rigs, so you know it's strong. The tripoint has high holding power and low breakout force. Brands: Bruce, Claw.
Folding grapnel. Suitable for dinghies and daysailers because of its compact design (four to six flukes) and light weight. However, because of its light weight, it may not penetrate weedy bottoms. The folding grapnel is sometimes used to retrieve sunken objects.
Mushroom. Large mushroom anchors are commonly used as permanent mooring anchors. Similar small mushrooms, often coated with vinyl or plastic, are widely used in inland waters. It can be used as a lunch hook on lightweight boats in the 15-foot range, but is not an all-around efficient sailboat anchor.--
