Attwood Marine Slip-Ring Penetrating Fluke Anchor, Hot Dip Galvanized Steel

Overview

The Attwood Marine Slip-Ring Penetrating Anchor is a hot-dip galvanized steel fluke anchor range made for holding in mud, sand, or gravel while stowing flat when not in use.

This anchor uses pivoting flukes that rotate downward into the bottom, with an arc-welded steel assembly that keeps the fluke-to-shank angle consistent as it sets. The slip-ring shank helps with retrieval when the anchor is snagged, which is useful around uneven bottom, debris, or mixed holding ground.

The range includes Size #5, Size #7, Size #10, and Size #13 options, so the same anchor style can be matched to different small boat, tender, pontoon, kayak, and fishing setups.

Key features

• Slip-ring shank helps release a snagged anchor by changing the pull angle during retrieval.
• Pivoting flukes rotate downward so the anchor can dig into mud, sand, or gravel bottoms.
• Hot-dip galvanized steel construction helps resist corrosion in wet anchor lockers and around saltwater spray.
• Arc-welded steel assembly keeps the fluke-to-shank geometry consistent for a steady set.
• Flat-stowing fluke format saves space in small lockers, skiffs, pontoons, kayaks, and tenders.

Variants

This anchor is offered in four size configurations for different anchoring setups.

The size changes between variants, while the slip-ring shank, pivoting flukes, hot-dip galvanized steel construction, and flat-stowing fluke format remain consistent across the range.

• 9960-1: Size #5. This is the smallest size in the group, suited to compact storage areas and lighter small-boat anchoring setups.
• 9961-1: Size #7. This size adds more anchor body than Size #5 while keeping the same flat-stowing fluke layout.
• 9962-1: Size #10. This option fits setups where a larger fluke anchor is needed without changing to a different anchor style.
• 9963-1: Size #13. This is the largest size in this range and gives more anchor size for boats that need the upper end of the series.

Sizing and onboard use

Match the anchor size to the vessel length, displacement, windage, bottom type, rode, chain, and local conditions. A fluke anchor depends on scope and bottom engagement, so it should be set with a steady pull and checked after a wind or current shift.

This range makes sense for boaters who need a simple anchor that stores flat and works over common soft or mixed bottoms. It is a practical fit for day boating, fishing, beach stops, tenders, pontoon use, and dockside backup anchoring where mud, sand, or gravel are expected.

Retrieval and care

The slip-ring layout helps when the anchor loads up under a rock, root, or obstruction because the pull can shift toward the opposite end of the shank during recovery. After use, rinse off mud, sand, and salt, then let the anchor dry before it goes back into the locker so buildup does not collect around the ring or fluke pivots.
