7 Knots Every Boater Should Know

Quick Summary

We cover the 7 essential boat knots every boater should know, from the all-purpose bowline to the load-securing trucker’s hitch. Each knot includes our own step-by-step tying instructions, a quick-reference table for choosing the right knot for the job, and tips for keeping our dock lines in good shape all season.

As we wait patiently — or not so patiently — for the boating season to start, this is a perfect time to brush up on all the stuff we boaters need to know. Like safety regulations. Or the finer points of maneuvering through locks. Or why bananas on board are a serious no-no.

Knots play a key role in boating, and experienced boaters understand which one to use for each task and how to secure it efficiently. Beginners may have only tied simple knots before, while seasoned sailors might just need a quick refresher. Staying sharp with knot-tying skills helps ensure safety and confidence on the water.

If we ask 100 boaters which knots matter most, we’ll probably get 99 different answers. That said, most experts agree on a core set. Below, we walk through the 7 knots we consider essential for any boater’s repertoire, plus a quick-reference table so we can find the right knot fast.

What Are the 7 Basic Boating Knots?

The 7 basic boating knots every boater should know are the bowline, anchor bend, clove hitch, trucker’s hitch, cleat hitch, reef knot, and figure eight. Together, these cover most of the tasks we run into on the water: securing a line to a ring or rail, tying up to a dock, tensioning a load, joining two lines, and stopping a line from running out.

Which Knot Should You Use?

Use this table to match the task in front of us to the right knot before we start tying.

Task	Best Knot
Securing a line to a mooring ring or piling	Bowline
Tying a line permanently to an anchor	Anchor Bend
Attaching a fender to a rail (quick, adjustable)	Clove Hitch
Tensioning and securing a load or dinghy	Trucker’s Hitch
Tying up to a dock cleat	Cleat Hitch
Joining two lines of equal thickness	Reef Knot
Stopping a line from running through a block	Figure Eight

Bowline

The bowline knot ranks among the most widely used knots in boating, valued for its strength and the ease with which it can be untied after use. Its versatility makes it suitable for a variety of tasks on the water. Keep in mind that it may loosen when not under tension and can be less reliable with slick materials like polypropylene.

How to tie a bowline:

1. Form a small loop in the standing line, leaving a working end long enough to finish the knot.
2. Pass the working end up through the loop from underneath, so it looks like a rabbit coming out of a hole.
3. Wrap the working end behind the standing line above the loop.
4. Feed the working end back down through the loop, following the same path it came out of.
5. Pull the standing line and the loop in opposite directions to tighten, then snug the working end against the knot.

Anchor Bend

The anchor bend is a reliable and sturdy knot that remains fairly straightforward to tie. It works well in situations where a secure hold is essential, such as fastening a line to an anchoring ring. Due to its strength, it can become difficult to untie and may sometimes need to be cut free.

How to tie an anchor bend:

1. Pass the working end of the line through the anchor ring twice, creating two turns around the ring.
2. Bring the working end across the standing part and tuck it under both turns to form a half hitch.
3. Take the working end and tie a second half hitch just above the first, around the standing line.
4. Snug both half hitches down firmly against the ring.
5. Finish with a seizing (a few tight wraps and a small knot) around the working end and standing line for extra security.

Clove Hitch

The clove hitch is known as a “temporary” knot since it’s fast to tie, simple to loosen, and easy to adjust after it’s secured. It proves especially useful when attaching a fender to a grab rail or in situations where the rope length may need quick adjustments.

How to tie a clove hitch:

1. Wrap the line once around the rail or post, crossing over itself to form an X.
2. Wrap the line a second time around the rail, just above the first wrap.
3. Tuck the working end under the second wrap, next to the X.
4. Pull both ends to snug the hitch tight against the rail.
5. Check that both wraps are parallel and the crossing point is secure before loading the line.

Trucker’s Hitch

The trucker’s hitch, sometimes called a wagoner’s hitch, is commonly used for securing loads to a deck or fastening a dinghy during rough conditions. It maintains a tight hold under tension while still being easy to release afterward.

How to tie a trucker’s hitch:

1. Tie a loop partway down the line (a slipped loop works well) to act as a pulley point.
2. Run the working end around your anchor point, then back up through the loop.
3. Pull down on the working end to create mechanical advantage and tension the line.
4. Hold the tension and tie off the working end with two half hitches around the standing part.

1. Tuck any excess line so it will not catch on gear while underway.

Cleat Hitch

The cleat hitch is a widely used knot for securing a vessel to a dock or boat lift. Even with its strong hold, it remains simple to tie and release when needed.

How to tie a cleat hitch:

1. Wrap the rope around the base of the dock cleat once, starting from the side closest to the boat.
2. Make one turn around the cleat, passing the rope over the top and around the opposite horn.
3. Continue wrapping the rope around the cleat in a figure-eight pattern.
4. Finish with a loop over one horn, then tuck the rope under the final turn to lock the knot.
5. Pull the free end firmly to tighten the hitch, then check that it holds securely.

Reef Knot

Many boaters turn to the reef knot when joining two lines of equal diameter or fastening a bundle of gear. Sailors often favor it for tasks like reefing and furling sails due to its simplicity and reliability.

How to tie a reef knot:

1. Cross the right-hand line over the left-hand line and tuck it under.
2. Cross the same end (now on the left) over the other line and tuck it under again.
3. Pull both working ends and both standing ends apart evenly to tighten.
4. Check that the knot looks symmetrical, with both ends exiting on the same side.
5. Avoid using this knot for critical loads; it is best for bundling and joining lines of equal thickness.

Figure Eight

Also called a stopper knot, the figure eight is commonly used to keep the end of a line from running through a block, fairlead, or similar fitting. It’s simple to tie, easy to recognize, and useful to have in any boater’s knot-tying repertoire.

How to tie a figure eight:

• Make a loop in the line, crossing the working end over the standing part.
• Bring the working end around behind the standing part.
• Feed the working end down through the loop you made in step one.
• Pull both ends to tighten the knot into a clean figure-eight shape.
• Use it as a stopper knot at the end of a line to keep it from running through a block or fairlead.

Okay, time to grab a rope and start practicing. Happy knotting!

How to Clean and Care for Your Dock Lines

Knots only hold as well as the line they’re tied in, and salt, grime, and UV exposure break lines down faster than most of us expect. A quick rinse with fresh water after every outing keeps salt crystals from working into the fibers. For deeper cleaning, use a cleaner appropriate for the line material according to product directions to help remove grease and grime that fresh water leaves behind.

Once our lines are clean, coil them loosely and store them out of direct sun when we’re not using the boat. Inspect for chafe near cleats and rings each time we clean, since that’s usually where a line fails first.

Check our product lineup to find the right cleaner for your boat’s surfaces and follow product directions.
