Sea-Dog Folding Grapnel Anchor – 18 lb. | Boats 18–26 ft.

Sea-Dog Folding Grapnel Anchor – 18 lb. | Boats 18–26 ft.

The Sea-Dog Folding Grapnel Anchor in 18 lb. is built for mid-to-large powerboats, cruisers, and sportfishers in the 18–26 ft. range. Four forged flukes fold flat against the shank for compact, space-saving storage and lock securely in both the open and closed positions — keeping the anchor ready to deploy and safe to stow in tight anchor lockers.

The grapnel design provides effective holding power across a wide range of bottom types including mud, sand, gravel, and rock — making it more versatile than a standard fluke anchor in mixed or hard-bottom conditions. At 18 lb., it also makes a capable kedge or secondary anchor on larger vessels.

Note: Recommended line and chain sizes are shown in product specifications. Line and chain are not included.

Parts Desk Insights

The 18 lb. Sea-Dog Folding Grapnel is the right choice for owners of mid-to-large vessels in the 18–26 ft. range who want the versatility of a grapnel design — particularly useful in anchorages with rocky, gravelly, or mixed bottoms where a standard fluke anchor won’t set reliably. The folding design keeps it compact and manageable despite its weight, and the lockable flukes make it safe to stow in anchor lockers without risk of snagging. At 18 lb., it also makes a capable kedge anchor on larger vessels where a compact, stowable secondary is needed. Line and chain are not included — recommended sizes are 3/8” line (150 ft.) and 1/4” chain (10–20 ft.).
