Aluminum fluke anchor with appropriate chain and rode delivers good holding power in lightweight package. Many options exist.

If you’re wondering, yes, you still do need an actual anchor—or “ground tackle” as the anchor and attaching line is called—in this day of the Power-Pole , Minn Kota Talon , and GPS anchoring. A physical anchor has one advantage: It’s always functional. When all your electronics go dead and you’re blowing down on a rocky jetty, a good anchor can save your boat—and maybe your crew.
Anchor Types Anchors come in a confusing array of designs including the Danforth or fluke, plow, claw, navy and Rocna or self-righting models. Most of the brands do a good job so long as you buy one large enough for your particular boat’s size, windage and the depth and bottom conditions where you’re most likely to anchor. It takes a lot more holding power to secure a 30-footer over a grouper reef in 200 feet than it does to hold a 20-foot bayboat in place on the grassflats.
Most recreational anchors are made of galvanized carbon steel, economical and rust-resistant, or stainless steel, better looking but also more expensive. Navy anchors have cast iron or steel flukes—heavy but effective.
A few like the Fortress and the Lewmar LFX series are made of anodized aluminum-magnesium alloy, giving the combination of minimal weight, corrosion resistance, strength and holding power.

The SeaClaw , sort of a re-engineered fluke/navy anchor, is legendary among flats guides for its compact size and great holding power, even without chain. The 6-pounder will hold most flats and bay boats, but it’s available in multiple sizes.
Choosing the Right Size Whatever design you choose, getting the right weight or size is important. For bay and flats boats, the typical charts recommending anchor weights are overkill because these boats have very low windage and are usually anchored for short periods in relatively shallow water—a fluke or Sea Claw style anchor of 8 to 10 pounds is plenty for most anglers in this category. For fishboats to 22 feet or so, anchors that fold flat when not in use give a big advantage in not taking up much storage space.
At the other end of the scale, a 45-foot sportfisher is going to take a seriously heavy anchor due to the weight and windage of the boat, as well as the fact that it’s likely at times to be anchored in deep water or maybe overnight. But on the sportfish, you can add an electric windlass to do the grunt work so that extra weight is not an issue.

Whatever anchor you choose, adding 6 feet or more of stainless or galvanized chain will give it much better holding power by keeping the shank near bottom and the direction of pull horizontal.
The Issue of Scope Even with a great anchor design, holding bottom will be difficult without enough anchor rode—the attaching rope and usually chain that connects to the boat. The lower the angle of pull on the rode, the greater the holding power in most patent anchors.
The anchor line—7⁄8 -inch line is much easier to handle than ½, even for smaller boats—should allow for at least 3 times the water depth if you plan on mostly anchoring briefly over fishing spots on lakes, bays and rivers. If you want to anchor for extended periods, you need at least 5 to 7 times the depth, and for deep water and rough conditions, 10 times the depth. If you never fish much deeper than 10 feet you can get by with 50 feet, but if you go offshore, you’ll want a lot of line.
