The Attwood Anchor Ring and Rope is a retrieval and marking kit, not a holding-power upgrade: a galvanized steel ring attaches to the anchor's crown — the end opposite the shank — with a length of rope running up to a separate marker buoy at the surface. It doesn't change how the anchor sets in the bottom. What it gives you is a second, crown-side line so you can locate a submerged anchor and pull it free by the crown — breaking it out backwards — if it fouls on rock, coral, or debris, without having to work the primary rode from the shank.

What is the Attwood Anchor Ring and Rope system?
The Attwood Anchor Ring and Rope is a packaged retrieval kit from Attwood Marine, a brand with decades of experience manufacturing marine hardware for recreational boaters. The system centers on a galvanized steel ring that attaches to the anchor's crown — the point opposite the shank, where the flukes pivot. A separate rope runs from that ring up to a marker buoy (sold separately) floating on the surface. Galvanized construction resists corrosion in both freshwater and saltwater, essential for hardware that spends extended time submerged.
The included braided polypropylene rope floats on the surface, a significant advantage in shallow-water anchoring because floating line is less likely to foul a propeller during retrieval. Polypropylene is UV resistant and stays flexible across a wide temperature range, making it well suited for extended outdoor use. Attwood rates this kit to lift anchor systems up to 80 lb, provided at least 10 feet of chain is used between the anchor and the primary rode.
What does the anchor ring actually do — and what does it not do?
It doesn't do what a lot of anchor-hardware marketing implies: it isn't a shank-side device and it doesn't change the angle of pull that sets the anchor in the bottom. That job is done entirely by scope and by the primary rode running from the shank, the same way it works with or without this kit.
What the crown-attached ring and buoy line actually solve is a real, separate problem: if the anchor gets fouled on rock, coral, or debris and won't break free by pulling from the shank the normal way, a line to the crown lets you pull from the opposite direction — the same direction the flukes dug in from — which is a far more reliable way to back a stuck anchor out. The marker buoy also shows you exactly where the anchor sits, useful in murky water or when you need to reposition without dragging.
Actual holding power still comes from the fundamentals: most recreational anchors hold by burying their flukes into the seabed, not by dead weight. As load is applied through the primary rode, a low, near-horizontal pull angle drives the flukes downward and forward into the bottom, while a steep pull angle can lift and trip them. That pull angle is controlled by scope (how much rode you pay out relative to depth) and by chain weight/catenary near the anchor — not by anything the crown ring does.
How do I anchor a boat step by step?
Proper anchoring begins before the anchor ever leaves the boat. Select your anchorage for protection from wind and waves, check your chart for bottom type (sand and mud hold best), and confirm you have enough swinging room. Always anchor from the bow — anchoring from the stern sits the hull broadside to wind and waves, creating instability and a risk of swamping.
Once in position, motor slowly upwind or upcurrent of your target spot and lower — never throw — the anchor to the bottom. Pay out rope as the boat drifts back, secure the line, and apply gentle reverse throttle to set the anchor. Standard scope is 5:1 to 7:1, meaning five to seven feet of rope for every foot of water depth. In 10 feet of water that is 50 to 70 feet of rode. Always account for tide rise when calculating depth.
How do I anchor a boat in a lake?
Anchoring in a lake follows the same scope ratios as open water, but lake conditions often allow shorter scope because there is no tidal change and wave action is generally lower. A 5:1 scope is typically sufficient in calm lake conditions. Lake bottoms with rock, stumps, or weed beds are exactly where a crown-attached retrieval line like the Attwood ring earns its keep — if the anchor snags, you can pull it free from the crown instead of dragging or cutting the primary rode.
How do I anchor a pontoon boat?
Pontoon boats have high freeboard and large surface areas, making them especially susceptible to wind drag. Use a heavier anchor than you would for a V-hull of the same length, and increase scope to 7:1 as a default. A retrieval ring and marker buoy is a practical add-on for pontoons working weedy or rocky lake bottoms, since it gives you a fast way to locate and free a fouled anchor rather than fighting it from the shank end.
Which anchor rope size should I choose?
Choosing the right rope length and diameter is a safety calculation, not an option. The Attwood system is designed for small to mid-size recreational boats, and rope diameter should increase with boat length and displacement. The table below outlines common boat types and appropriate rope sizing.
| Boat / Application | Boat Length | Recommended Rope Diameter |
|---|---|---|
| Small Runabout / Jon Boat | Up to 16 ft | 3/8 in (9.5 mm) |
| Pontoon Boat / Bowrider | 17–24 ft | 1/2 in (12.7 mm) |
| Cruising Sailboat | 25–35 ft | 5/8 in (15.9 mm) |
| Larger Cruiser / Coastal Vessel | 36 ft and above | 3/4 in (19 mm) or chain |
For boats at the upper range of the Attwood system's intended application, pair the polypropylene rope with a short length of galvanized anchor chain between the anchor and rope. Chain adds weight that keeps the pull angle low and provides abrasion resistance where the rode contacts rocky or coral bottoms — something polypropylene alone cannot offer.
Frequently asked questions
How does the Attwood Anchor Ring and Rope system work?
The ring attaches to the anchor's crown, with a rope running to a separate marker buoy (sold separately). It doesn't change how the anchor sets — that's controlled by scope and the primary rode. What it gives you is a way to locate the anchor and, if it fouls, pull it free from the crown rather than the shank. Attwood rates the kit to lift anchor systems up to 80 lb when at least 10 feet of chain is used.
Is the Attwood kit suitable for my sailboat?
It is designed for small to mid-size recreational boats, day sailers, and pontoons in protected waters. Confirm your boat's anchor weight and cleat sizing against Attwood's specifications before purchasing.
What scope should I use when anchoring?
Use 5:1 to 7:1 — five to seven feet of rode for every foot of water depth, accounting for tide rise. Calm lakes often allow 5:1, while high-windage pontoons and exposed spots call for 7:1.
Should I anchor from the bow or the stern?
Always anchor from the bow. Anchoring from the stern sits the hull broadside to wind and waves, creating instability and a real risk of swamping.
Why does the floating polypropylene rope matter?
Because it floats, the rope stays clear of the surface during retrieval and is less likely to foul the propeller — a meaningful advantage in shallow-water anchoring.
