Advanced Sailing Knots for Sailors: Beyond the Basics for Cruising & Racing

You’ve mastered the bowline, the cleat hitch, and the trusty figure eight. You can tie them in your sleep, in the dark, and with one hand behind your back. But as you’ve expanded your sailing horizons, perhaps venturing into longer coastal cruises or even dabbling in racing, you’ve likely realized that the world of knots goes far beyond the basics. There are specialized advanced sailing knots for specific loads, quick releases, temporary repairs, and even for creating mechanical advantage.

At Salty & Windy, we understand that feeling of wanting to elevate your seamanship. You’re a coastal cruiser now, and you need a toolkit of knots that are as versatile and reliable as your boat. This isn’t just about showing off; it’s about efficiency, safety, and confidence on the water. We’re here to guide you through the next level of knot mastery, ensuring you’re prepared for any situation the sea throws your way.

If you’re still brushing up on the fundamentals, we highly recommend checking out our foundational guide: Basic Sailing Knots: Your Essential Onboard Guide. For everyone else, let’s dive into the advanced world where strength, efficiency, and ingenuity truly shine.

Why Advanced Knots Are Crucial for Coastal Cruisers

As you spend more time on the water, you encounter a wider array of challenges. A standard sheet bend might work for many applications, but what if you need to join two lines of vastly different diameters? What if you need to secure a fender line to a stanchion that’s constantly under chafe? Or perhaps you need to create a temporary purchase system to hoist something heavy?

Advanced sailing knots aren’t just “fancier” versions of what you already know. They are purpose-built solutions to common (and uncommon) sailing problems. They offer:

• Increased Security: Some knots are designed to hold better under specific types of load or in particular materials.
• Greater Efficiency: Certain knots are quicker to tie, easier to untie after being loaded, or better suited for specific tasks.
• Versatility: Learning a few key advanced knots can unlock a multitude of solutions for rigging, repairs, and mooring.
• Enhanced Safety: Knowing the right knot for the right situation can prevent gear failure, damage, or even injury.

Essential Advanced Knots for Your Sailing Toolkit

We’ve curated a selection of 7-10 indispensable advanced sailing knots that will significantly enhance your capabilities as a coastal cruiser. For each, we’ll explain its purpose, when to use it, and provide step-by-step instructions (with placeholders for diagrams).

Knots for Rigging & General Use

1. The Rolling Hitch (or Tautline Hitch)

Purpose: This is a friction hitch used to attach a line to another line, a spar, or a rail, especially when the line will be under load and you need it to hold securely without slipping, but also be adjustable. It’s incredibly versatile.

When to use it: Securing a fender to a vertical stanchion (allowing adjustment), creating a temporary sheet lead, making a temporary repair to a damaged line by taking the strain off a weak point, or even as a temporary dinghy painter attachment.

My Experience: I once had a jib sheet develop a nasty chafe spot during a blustery coastal run. Instead of cutting it short or risking a full break, I used a rolling hitch with a spare line to bypass the damaged section, taking the load off it until we could get into port for a proper repair. It held strong for hours, proving its worth in a tricky situation where a simple clove hitch would have slipped immediately. It’s a lifesaver for temporary fixes and securing things that need to be adjusted.

How to tie it:

1. Pass the working end around the spar/line once, going over itself.
2. Repeat this, making a second turn around the spar/line, again going over itself and keeping the turns parallel.
3. Now, pass the working end around the spar/line a third time, but this time, go outside the first two turns and then tuck it underneath itself.
4. Tighten the knot by pulling on both the standing part and the working end.

2. The Figure Eight Bend

Purpose: A strong, reliable, and easily inspectable knot for joining two lines of similar or slightly different diameters. It’s less prone to slipping than a sheet bend under certain conditions.

When to use it: Extending a dock line, joining two halyards for hoisting, or creating a longer anchor rode from two sections.

How to tie it:

1. Tie a standard figure eight knot in the end of the first line, but don’t tighten it fully.
2. Take the working end of the second line and follow the path of the first figure eight knot in reverse.
3. Trace the entire knot, ensuring the two lines run parallel to each other.
4. Pull both standing parts and both working ends to tighten the knot evenly.

3. The Cleat Hitch (Advanced Techniques)

Purpose: While you likely know the basic cleat hitch, mastering advanced techniques ensures maximum security and quick release, especially for mooring lines under heavy load.

When to use it: Securing dock lines, spring lines, or mooring lines to deck cleats.

Advanced Tips:

• Never “Frap” or “Figure Eight” too many times: Two or three figure-eight turns are usually sufficient. Too many turns can make it impossible to untie under load.
• The “Locking Turn”: After your figure-eight turns, make one final turn around the base of the cleat, tucking the line under the final cross-over. This creates a secure “locking” action without making it impossible to untie.
• The “Half Hitch” for Quick Release: For temporary situations or when anticipating a quick departure, you can finish with a simple half-hitch over one horn, which can be easily flipped off. However, this is less secure for long-term mooring.

How to tie it (with locking turn):

1. Take a full turn around the base of the cleat furthest from the direction of pull.
2. Cross over the top of the cleat, making a figure-eight turn around the opposite horn.
3. Repeat the figure-eight turn.
4. For the final turn, bring the working end under the last figure-eight, creating a “locking” half-hitch.

Advanced Sailing Knots for Anchoring & Mooring

4. The Anchor Bend (Fisherman’s Bend)

Purpose: Considered one of the most secure knots for attaching an anchor rode to an anchor shackle. It’s designed to hold under constant, heavy, and often oscillating loads.

When to use it: Permanently or semi-permanently attaching your anchor rode to your anchor. This is not a knot you want to fail!

How to tie it:

1. Pass the working end twice through the anchor shackle or ring.
2. Bring the working end around the standing part and tuck it through the two initial turns you just made.
3. Pull this loop tight. This forms a “clove hitch” around the standing part.
4. Make a final half hitch around the standing part, just above the first knot.
5. For extra security, you can often add a seizing or whip the bitter end to the standing part.

5. The Mooring Hitch (Tugboat Hitch)

Purpose: A quick-release hitch for securing a boat to a piling or bollard, allowing for rapid departure if needed.

When to use it: Temporary mooring, especially when you might need to leave in a hurry or are just stopping briefly. Not recommended for long-term unattended mooring.

How to tie it:

1. Pass the line around the piling or bollard.
2. Bring the working end over the standing part and then under, forming a loop.
3. Pass the working end through this loop from underneath.
4. Now, form a bight (a loop) with the working end and pass this bight through the loop you just created.
5. Tighten the knot by pulling on the standing part. To release, simply pull the working end (the bight).

Emergency & Specialized Knots

6. The Marlinspike Hitch

Purpose: A temporary hitch used to attach a marlinespike (or any similar tool like a screwdriver handle) to a line, allowing you to gain leverage to tighten or untighten other knots.

When to use it: Freeing a seized knot, tightening lashings, or creating a temporary handle on a line.

How to tie it:

1. Form a bight (loop) in the line.
2. Twist the bight so that one side crosses over the other, creating two smaller loops.
3. Insert the marlinespike through both of these smaller loops, ensuring it passes through from the same side.
4. Pull on the standing part of the line to tighten the hitch around the marlinespike.

7. The Trucker’s Hitch (or Lorryman’s Hitch)

Purpose: A compound knot system that creates a mechanical advantage, allowing you to apply significant tension to a line.

When to use it: Securing a dinghy on deck, lashing down gear, creating a temporary clothesline, or tightening a tarp over a cockpit. It’s essentially a simple block and tackle system using knots.

How to tie it:

1. Secure one end of your line to a fixed point with a bowline or cleat hitch.
2. Along the standing part, create a non-slip loop. A simple figure eight on a bight works well here, or even a slipped overhand knot if you need a quick release.
3. Pass the working end around the second fixed point (e.g., another cleat or padeye).
4. Thread the working end through the loop you created in step 2.
5. Pull on the working end to create tension (you’ll feel the mechanical advantage).
6. Secure the working end to the loop (or to the second fixed point) with two half hitches or a similar secure knot.

8. The Prusik Knot

Purpose: A friction hitch that can slide freely along a rope when not under load, but “bites” and holds firmly when weighted. It’s a critical safety and utility knot.

When to use it: Ascending a mast in an emergency, creating a temporary adjustable foot loop, or as a safety backup when working aloft. You’ll need a separate, thinner cord (prusik cord) for this.

How to tie it:

1. Take a loop of thinner cord (prusik cord) and lay it across the main rope.
2. Wrap one side of the prusik loop around the main rope, passing it through the other side of the prusik loop. Do this 3-5 times.
3. Ensure the wraps are neat and parallel.
4. Pull on the prusik loop to tighten the wraps around the main rope. It should slide when not weighted and grip when weighted.

9. The Bowline on a Bight

Purpose: Creates two strong, non-slip loops in the middle of a line, or a single loop that is exceptionally strong and resistant to capsizing, without using the ends of the rope.

When to use it: Creating a bosun’s chair in an emergency, hoisting a person, creating a strong attachment point in the middle of a line, or even as a temporary bridle.

How to tie it:

1. Form a bight in the middle of your line.
2. Tie a small overhand knot in the bight, but don’t tighten it. This forms a small loop.
3. Bring the entire bight up and pass it through the small loop from underneath.
4. Open the bight and pass it around the base of the overhand knot, encompassing the two standing parts.
5. Pull the two standing parts to tighten the knot, drawing the bight down securely. You will now have two loops.

Practicing Advanced Sailing Knots Makes Perfect (and Safe)

Learning these advanced sailing knots isn’t just about memorizing steps; it’s about understanding their purpose and getting the muscle memory down. Practice them at home, on your boat at the dock, and even blindfolded or with gloves on. The more comfortable you are, the more confident you’ll be when you really need them.

Remember, a well-tied knot is a beautiful thing – strong, efficient, and reliable. A poorly tied knot is a liability. Always double-check your work, and don’t hesitate to untie and re-tie if it doesn’t look right.
