Choosing the right anchor for a pontoon boat matters more than most owners expect. Pontoons catch wind like a sail because of their flat, boxy hulls, and they often lack the deep keel that helps a monohull dig in. A good anchor for a pontoon boat has to hold in soft mud, sand and weed, reset cleanly when the wind shifts, and stow without tangling your deck furniture. This guide compares seven anchor types and models that suit different lakes, boat weights and anchoring habits, so you can narrow the field before you buy.

Lewmar Delta Anchor
Owners who want one anchor that handles several bottom types without much fuss often look at delta-style designs. The Lewmar Delta is a well-known name among boaters and is commonly used on mid-size vessels.
Key specs
- Delta (plow-style) fluke geometry
- Stainless or galvanized options depending on version
- Sized by boat length and rode requirements
Pros
- Versatile across sand, mud and mixed bottoms
- Established manufacturer with a solid reputation
- Balanced design for predictable setting
Cons
- Not the top choice in heavy weed
- Larger sizes can be bulky to store on a pontoon
Bruce Claw Anchor
Light pontoons and owners who anchor for short stops, such as lunch breaks in a cove, may prefer a claw-style anchor. The Bruce claw shape is known for grabbing weed and debris more readily than flat-fluke designs, which some owners find useful in grassy lake bottoms.
Key specs
- Three-claw geometry in galvanized steel
- Compact footprint for stowage
- Sized for small to mid-size recreational boats
Pros
- Compact and easy to stow
- Handles weed and grassy bottoms reasonably well
- Simple, durable construction
Cons
- Holding power is generally lower than plow-style anchors in sand
- Claws can snag rode and debris during retrieval
Eliet Zinc Anchor
Owners who keep their pontoon in saltwater or brackish water, or who simply want an anchor that resists corrosion for years, often look at zinc-coated or galvanized options. The Eliet is a recognized name in this category.
Key specs
- Galvanized or zinc-treated steel construction
- Designed for light to mid-weight recreational use
- Available in several sizes for different boat lengths
Pros
- Corrosion-resistant finish suits marine environments
- Reasonable weight for pontoon deployment
- Easy to inspect for coating wear
Cons
- Coating can chip over time and needs periodic checks

Buying Guide
Selection Criteria Used in This Guide
The picks above were chosen through specification review, brand reputation within boating communities and recurring themes in owner feedback. No anchor here was tested in a lab or on our own boats. Treat the notes as a starting point, then verify fit against your specific pontoon.
Important Features to Look For
- Holding power: Matched to bottom type. Plow and delta designs generally perform well in sand and mud, while claws can handle weed better.
- Reset behavior: Anchors that reset cleanly when wind or current changes reduce the risk of dragging.
- Corrosion resistance: Galvanized, zinc-coated or stainless finishes last longer in wet environments.
- Stowability: Pontoon decks have limited space, so compact or folding designs are easier to manage.
Specs to Check Before You Buy
- Boat length and weight: Manufacturers typically size anchors by boat length and displacement. Use their chart as the baseline.
- Wind exposure: Pontoons with cabins, bimini tops or tall rails catch more wind and may need one size up.
- Rode length: A common guideline is roughly 5 to 7 times the water depth at the bow for chain-and-rope setups. Confirm this with your local marina or a qualified marine professional.
- Shank and fluke material: Steel is strong but heavy. Aluminum is light but may not suit every bottom.
Choosing by Need
- Calm, sandy lake: A lightweight fluke or delta design in a smaller size is usually sufficient.
- Weedy or mixed bottom: A claw or roll-bar design may hold better with less fouling.
- Frequent wind or current: Consider a self-righting or high-holding anchor one size larger than the chart suggests.
- Saltwater or brackish use: Prioritize stainless or heavily galvanized options and plan for regular inspection.
Things to Watch Out For
- Undersizing is the most common mistake. When in doubt, go one size up.
- Check the shackle, swivel and rode attachment, not just the anchor itself. Weak links cause failures.
- Inspect galvanizing or coating each season and replace the anchor if the metal shows pitting.
- Never anchor a pontoon in a way that leaves the boat unattended in strong weather without a plan. Consult a marine professional for safe anchoring practices in your area.
FAQ
What size anchor does a pontoon boat need?
Size depends on boat length, weight, and wind exposure. Most manufacturers publish charts by length. Owners of pontoons with cabins or tall canopies often go one size up for extra margin.
Is a fluke anchor or a claw anchor better for a pontoon?
Fluke and plow designs generally perform better in sand and mud, while claw-style anchors can handle weed and debris more readily. Your typical bottom type should guide the choice.
How long should the anchor rode be?
A common guideline is 5 to 7 times the water depth at the bow for a rope-and-chain setup. Local conditions and marina rules may differ, so confirm with a local professional.
Do I need chain on my pontoon anchor line?
A short length of chain between the anchor and rope helps keep the pull low and reduces chafe on the bottom. Many owners use a few feet of chain as a practical compromise for weight and handling.
How do I clean and maintain a pontoon anchor?
Rinse the anchor after each use in freshwater, check for mud and weed buildup, and inspect the galvanizing or coating for wear. Replace shackles and swivels if they show corrosion.
Can I use a pontoon anchor in saltwater?
Yes, but choose stainless or heavily galvanized materials and rinse thoroughly after each saltwater trip. Saltwater accelerates corrosion, so inspection frequency should increase.
What is the best way to deploy an anchor from a pontoon?
Approach the anchoring spot slowly, lower the anchor from the bow, and let the boat drift back while paying out rode. Set the anchor by backing gently, and confirm it is holding by checking position against a shoreline reference or GPS.
Conclusion
For small pontoons on calm, sandy lakes, a lightweight fluke design such as the Fortress FX-37 Aluminum Anchor or a Danforth-style anchor is a practical fit. Owners of mid-size pontoons in mixed bottoms may prefer the reset behavior of the Rocna Vulcan Anchor or the all-round balance of the Lewmar Delta Anchor. Larger, wind-exposed pontoons often benefit from the high holding power of the Mantus M1 Anchor. For weedy shallows and short stops, the Bruce Claw Anchor is worth a look, while owners in saltwater or brackish areas should consider the corrosion resistance of the Eliet Zinc Anchor. Always size by your boat’s length, weight and wind exposure, and check the rode and hardware before you head out.
