Different Types of Pontoon Boat Anchors

There exist three significant types of pontoon boat anchors namely; box anchors, grapnel style and fluke anchors. Each anchor has the specific design features that set it apart while at the same time ensuring its effectiveness in securing your boat in a particular type of surface.

One factor you need to keep in mind is that the anchor you pick will significantly rely on the type of water you are going to sail in.

Box Anchors

Box anchors work best in water bodies with muddy/slightly rocky bottoms. They are typically fitted with hooks which dig deep into the mud to get a firm hold.

Just like when you’re using other types of anchors, it is vital that you have an adequate line out when tossing your box anchor. Having a shorter line will prevent the anchor’s prongs from getting the perfect angle required for firmly locking into the mud.

Fluke Anchors

Fluke anchors have characteristically long arms that burrow deep into the bottom to secure your boat. This type of anchor delivers excellent service in water bodies with gravel/sandy bottoms. An exciting feature of fluke anchors is their power to weight ratio. For example, a 16 lb. fluke anchor can comfortably secure a 24’ to 30’ pontoon boat in waters with mild currents.

Pro tip. When purchasing a fluke anchor, its size should take center stage over its weight. The weight of the anchor only helps it sink to the bottom and dig its flukes into the ground for an excellent hold.

Grapnel Style Anchors

This type of anchor is designed for use in rocky bottoms. They have characteristically long arms that hook onto a rock to safely secure your boat.

How to Choose the Right Anchor for Your Boat

If you are looking to purchase an anchor for your boat here are a few pointers to take into consideration.


Weight always plays second fiddle when selecting an anchor. However, for a mid-sized pontoon boat, a 15-20 pound will work just fine. For a larger boat, you can go for a more massive anchor.

Heavier anchors will work better, but that’s no guarantee. Remember that most of these pontoon boat anchors rely much on design than weight to securely hold the boat.


Space is always an issue especially if you own a small boat. Therefore, its best you go for an anchor with foldable arms that packs downs to a small size. If you’re always on the go, one with a compact design will also be easier to carry around.

Build Material

Your anchor’s durability relies so much on the type of material used to build it. Most pontoon boat anchors are made using galvanized stainless-steel which is rust resistant. Additionally, if you find one with anti-fouling mechanics, the better.

Extra Features/Accessories

Some anchors are sold alongside handy features. These features may include, a retrieval ring, rope, and a padded storage bag. While it isn’t that much of a decisive factor, you can still consider it just to get the best deal for your money.

Setting Your Pontoon Boat Anchor

Here is a simple guide on how to set your pontoon boat anchor like a professional and under the least time possible. However, always exercise caution when you’re anchoring your boat.

Pick Out A Spot

Settle on where you want to anchor your boat. While at it, ensure that the boat is facing the wind/current direction.

Determine the Water’s Depth and Terrain at the Bottom

This may seem new to first-timers. Being familiar with the water’s depth will help you calculate which length of line you require to have your anchor latched firmly into the bottom.

The recommended amount of line is five times to the depth of the water is 5:1. This is in addition to the distance from the surface of the water to the anchor hooking point.

Switch the Engine Off

Its now time to turn the boat’s engine off, but before you do so, ensure the bow is a few meters ahead of your anchoring spot.

It’s Now Time to Anchor

Ensure that the anchor is securely fastened to the cleat before gently releasing it into the water. Do not throw the anchor for safety reasons as the line is more likely to intertwine.

Wind and water currents will drift your boat back a little to ensure the anchor sinks a little further away from the boat. If your boat is stationary, you can engage the reverse gear to move it slightly as you release the rode.

Fasten the Line

Once you’re comfortable with the anchoring to spot its now time you fasten the line to allow the anchor to dig in. Wrap the rode around the cleat two times. You can then reverse the boat slightly to ensure it backs down on the anchor for a firmer hold.

Retrieving Your Anchor

When you’re ready to leave, pull the anchor vertically to avoid scratching your pontoon. Clean the anchor of mud, dragging, or any other debris before storing it inside the boat.

Which type of anchor is right for my boat?

Well, this will largely depend on the terrain of the water bottom which you’re going to spend the most time on.

Here is a quick guide on the three major types of anchors and where they’re best suited. Box anchors work best in water bodies with muddy bottoms. Fluke anchors provide excellent service in water bodies with gravel/sandy bottoms. Grapnel style anchors are best suited for anchoring in waters with rocky bottoms.

What is the correct anchor size for my pontoon?

Should I consider water depth when purchasing an anchor?
