It's built for boats up to about 24 feet and sets fast in sand and gravel bottoms. Simple, heavy, and dependable, it's the kind of no-fuss ground tackle that just does its job weekend after weekend.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Attwood 9935B1 is a traditional Navy style anchor cast from solid iron and finished in a thick black PVC coating. It weighs 20 pounds, which is the sweet spot for a lot of runabouts, center consoles, and pontoons up to around 24 feet. If you spend your weekends anchoring off a sandbar or holding over a fishing spot in open water, this is the kind of no-drama ground tackle that just works, and it won't cost you a fortune.\u003c\/p\u003e\n\u003cp\u003eNavy anchors have been around forever for a reason. The heavy cast iron body sinks fast, and the fixed flukes dig into sand and gravel once you back down on the rode. There's nothing to fold, nothing to adjust, and nothing to jam. You drop it, pay out your line, and let the weight do the work. For a boater who wants a dependable lunch hook or an overnight anchor in protected water, that simplicity is the whole point.\u003c\/p\u003e\n\u003cp\u003eThe PVC coating isn't just for looks. Cast iron and gelcoat don't get along, and a bare anchor knocking around the locker or banging the swim platform will leave marks fast. The thick vinyl skin protects your hull, your deck, and your shins, and it slows the surface rust that raw iron picks up the second it hits salt water. Keep the coating intact and this anchor will ride in your locker season after season.\u003c\/p\u003e\n\u003cp\u003eThe name says Deep Water, and that's a fair description of where this anchor earns its keep. In a deeper anchorage you need enough weight to reach bottom and stay put while you let out scope. A dense cast iron body drops straight down and holds its ground while you pay out line. Aim for a scope of about seven to one, so roughly seven feet of rode for every foot of water depth plus your bow height, and you'll get the low pulling angle the flukes need to set.\u003c\/p\u003e\n\u003cp\u003eHere's the honest part. A 20 pound Navy anchor is happiest in sand and small gravel. In thick mud or heavy grass it can skate along until the flukes find something firmer, so pick your spot. It also likes a little chain. We tell folks to run at least six to ten feet of quarter inch chain between the anchor and the nylon rode. That chain keeps the shank pulling low and horizontal, which is what gets the flukes to bite instead of skipping across the bottom.\u003c\/p\u003e\n\u003cp\u003eMatch the size to your boat honestly. Twenty pounds holds a 20 to 24 foot boat nicely in a light to moderate breeze. If you regularly anchor in 20 knot winds, or you're running something bigger, step up in weight or carry a second anchor. Plenty of smart boaters keep a fluke style anchor aboard as a backup for the days the bottom won't cooperate. And mind your rode, or add a swivel, so a heavy cast iron anchor doesn't foul its own line as the boat swings.\u003c\/p\u003e\n\u003cp\u003eSetup is straightforward. Shackle a chain leader to the anchor ring, connect your nylon rode to the chain, and you're rigged. There's no assembly and no break-in period. Attwood has been building marine gear for over a hundred years, and the 9935B1 is about as classic as anchors get. It's a fair price for solid, coated cast iron, and it's a smart choice for a primary hook on a smaller boat or a backup on a larger one.\u003c\/p\u003e\n\u003cp\u003eMaintenance is easy too. Rinse it with fresh water after a day in the salt, and check the PVC coating now and then. If you drag it across rock or oyster shell and chip the vinyl, touch up the bare spot so rust can't creep under the coating. That's really the only upkeep a cast iron anchor ever asks for, and it's why a well cared for Navy anchor outlasts just about everything else in the locker.\u003c\/p\u003e\n\u003cp\u003eOne more tip from the dock. Retrieve it slowly and let it hang in the water for a minute to rinse off the mud before it comes over the rail, and stow it where it can't slide around underway. Treat it right and this is the last 20 pound anchor you'll buy for this boat.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e20-pound solid cast iron body sinks fast and holds position in deep water\u003c\/li\u003e\n  \u003cli\u003eTraditional Navy style fixed flukes dig into sand and gravel bottoms\u003c\/li\u003e\n  \u003cli\u003eBlack PVC coating protects your hull, deck, and finish from scratches and slows surface rust\u003c\/li\u003e\n  \u003cli\u003eAnchor ring accepts a standard shackle for an easy chain-and-rode setup\u003c\/li\u003e\n  \u003cli\u003eSized for boats up to about 24 feet in light to moderate conditions\u003c\/li\u003e\n  \u003cli\u003eFixed one-piece design with no moving parts to fold, jam, or adjust\u003c\/li\u003e\n  \u003cli\u003eAttwood part number 9935B1, from a marine brand with more than 100 years in the business\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Attwood Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat size boat is the 20 pound Navy anchor good for?\u003c\/summary\u003e\n    \u003cp\u003eTwenty pounds suits boats up to about 24 feet in light to moderate conditions, like runabouts, center consoles, and pontoons.
