Essential Knots

Eight knots cover 95% of situations on a sailing yacht. Learn them before you leave the marina.

Bowline
Loop that won't slip or jam

The "king of knots". Creates a fixed loop of any size that holds under load but releases easily. Use for: mooring lines to rings/bollards, rescue line around a person, attaching sheets to sails. Memory aid: "the rabbit comes out of the hole, around the tree, and back down the hole."

Cleat Hitch
Securing lines to cleats

The correct method for securing a line to a cleat: one full turn around the base, then figure-of-eight across the horns, finish with a locking half hitch. Do NOT just wrap multiple times — it jams under load. One full turn + two figure-of-eights is plenty for any load.

Clove Hitch
Quick temporary attachment

Fast to tie and easy to adjust. Best use: attaching fenders to rails, quick temporary mooring to a ring or bollard. Weakness: can slip if load direction changes, and can jam solid under sustained heavy load. Not for permanent or safety-critical applications.

Round Turn & Two Half Hitches
Attaching to rings and rails

Secure, reliable, and adjustable. The round turn takes the initial load while you tie the hitches. Use for: attaching to anchor rings, tying to fender rails, securing dinghies to rings. More secure than clove hitch for sustained loads.

Figure of Eight
Stopper knot

Tied at the end of a sheet or halyard to prevent it running through a block or clutch. Simple: make a loop, pass the end around and back through. Bulky enough to jam. Always tie figure-eights in your sheets before a sail — there is nothing worse than losing a sheet through a block at sea.

Reef Knot
Joining two lines of same diameter

"Left over right, right over left." The classic knot for reefing — tying off the reefing pennants around a furled sail. Not suitable for critical applications — it can capsize into a slip knot if pulled from the wrong direction. Never use to join two lines under load or different diameters.

Sheet Bend
Joining two lines of different diameters

The proper knot for joining two ropes of unequal thickness. Form a bight in the thicker rope, pass the thinner rope through the bight, around behind both parts of the thicker rope, and tuck under itself. Double sheet bend (two wraps of the thinner line) for very different diameters or slippery rope.

Rolling Hitch
Attaching to another line under tension

The knot you need when you have to attach to a loaded line without releasing it — e.g. taking a sheet to a winch when it is jammed under load, or attaching a preventer. Two round turns in the direction of load, then one turn on the other side, finish with a half hitch. The two turns must be toward the direction of pull.

Med Mooring — Stern-to (Mediterranean Mooring)

The standard mooring technique in the Mediterranean. You anchor and back the stern to the quay, securing with stern lines and anchor chain/warp to hold you off.

Preparation before approach:

  • Decide stern-to or bows-to (harbour dependent — check which side the shore power, water are on)
  • Prepare anchor: flake chain, remove lock pin, ready to drop instantly
  • Prepare two stern lines (minimum 15m each) with eye splices or bowlines
  • Fenders on both quarters at correct height for the quay
  • Crew briefing: who drops anchor, who handles stern lines, who guides from the stern

Stern-to Procedure (most common):

  1. 1Approach the berth at slow speed, bows toward the quay, assessing wind and current.
  2. 2When approximately 1.5–2× boat lengths from the quay, give the signal to drop anchor. Stop forward motion and begin reversing.
  3. 3Reverse slowly toward the quay, paying out anchor chain steadily. Do not let it pile up — it must be laid in a line, not a heap.
  4. 4When stern is close to the quay (about 1 metre off), pass stern lines ashore. Crew steps off or throws a line to someone on the quay.
  5. 5Secure stern lines loosely — don't pull the boat hard to the quay yet.
  6. 6Take up slack on the anchor chain until it is taut. This holds the bow off the quay and prevents the boat swinging into neighbours.
  7. 7Adjust stern lines to achieve correct gap from the quay (0.5–1m stern clearance typically) and equal tension each side.
  8. 8Set a snubber on the chain to prevent jerking in swell. Check chain angle — it should lead forward cleanly.

Common Mistakes:

  • Dropping anchor too late — you end up too close to the quay with too little chain out. Minimum 3:1 scope from quay.
  • Dropping anchor too early — chain piles up directly below the bow, provides no holding.
  • Pulling the stern hard to the quay — the boat lies with no shock absorption. Leave 0.5–1m gap.
  • Ignoring the neighbours' chains — always check where adjacent boats' anchors are lying before you drop yours.

Anchoring Procedure

Choosing a Spot:

  • Check depth: target 3–8m for overnight anchoring (chartplotter or echosounder)
  • Check holding: sand and mud = excellent. Rock, weed = poor. Check pilot book for bottom type.
  • Check swing circle: radius = chain out. Will you swing onto nearby boats, rocks, or shore?
  • Note forecast wind direction overnight — will the anchorage remain sheltered?

Scope Calculation:

Rode TypeMinimum ScopeRough Weather
All chain3:1 (calm), 5:1 (normal)7:1
Chain + rope5:1 (normal)8:1
All rope7:1 minimum10:1

Scope = total rode out ÷ depth at anchor (add freeboard of bow to depth reading). Example: 5m depth + 2m freeboard = 7m. At 5:1 = 35m of chain.

Setting the Anchor:

  1. 1Motor slowly over the spot where you want the anchor to lie (not where the boat will end up — remember the chain runs forward).
  2. 2Point into wind/current. Reduce to bare steerageway and stop. Nod to crew to drop anchor when motion is zero.
  3. 3Let anchor fall to bottom. Let out chain as boat drifts back slowly. Do not motor back yet — let weight of chain set the direction.
  4. 4Once enough chain is out, snub it briefly. Motor slowly astern at 1000 RPM to drag the anchor into the seabed.
  5. 5Increase throttle to 1500 RPM for 30 seconds while holding position. If chain stays taut and boat holds, anchor is set.
  6. 6Mark the GPS position. Set anchor drag alarm on chartplotter (typically 50–100m radius depending on swing).

Signs of Dragging:

  • Chartplotter alarm sounds (set this)
  • Chain goes slack then suddenly jerks taut repeatedly
  • Shore transits (aligned landmarks) change relative position
  • Sound of chain clanking on the bottom increases

Mooring to a Buoy

Many Greek anchorages and dive sites have mooring buoys. Always check the buoy's rating and condition before relying on it.

  1. 1Approach upwind or upcurrent, whichever is stronger, at slow speed.
  2. 2Aim to stop with the buoy at the bow, slightly to one side so crew can reach it with the boathook.
  3. 3Crew picks up the buoy pennant with boathook. Pass your own line through the pennant ring or pick-up loop — do not rely on the pennant itself.
  4. 4Secure with two lines from the bow (port and starboard bow cleats) for security.
  5. 5Check the buoy's condition: look for rust, rope chafe, missing shackle pins, weed overgrowth suggesting it hasn't been serviced. If doubtful, anchor instead.
A buoy rated for a 10m charter boat may not be suitable for an 18m motor yacht with nearby shallow water. When in doubt about the buoy's rating or ground tackle condition, anchor independently.

Coming Alongside

Preparation: fenders at correct height for the pontoon, bow and stern lines ready with enough length, spring lines prepared. Identify cleats on the pontoon.

Approach principles:

  • Approach at 30° to the pontoon in calm conditions. Too shallow and you drift away; too steep and you hit bow-first.
  • Always approach into the wind or current if possible — it gives braking power and control.
  • Slow down earlier than you think necessary. A boat stops slowly.
  • The bow spring is the most useful first line: it stops forward motion and allows you to use engine to swing the stern in.

Spring line technique in tight marinas: If wind is blowing you off the pontoon, secure the bow spring, then apply gentle forward engine with helm toward the pontoon — prop wash pushes the stern in against the spring. Very effective for a single-screw boat.

Propeller walk (twin or single screw): Single right-handed prop in reverse pulls the stern to port. Use this — come alongside starboard-to, and in reverse the stern pulls neatly to the pontoon. Going in port-to may require more anticipation.

Leaving a Berth

Spring-off technique: If wind or current holds you against the pontoon and prevents you simply motoring away:

  1. 1Remove all lines except the aft spring (running from stern cleat forward to a pontoon cleat amidships).
  2. 2Apply slow ahead engine with helm toward the pontoon. The bow cannot go forward (spring holds), so it is pushed by prop wash against the pontoon while the stern pivots away.
  3. 3When stern is clear, slip the spring, engage reverse, and motor clear.

Wind and current: Let them work for you — identify which way they will take the bow when you cast off. Use the free-swinging bow to your advantage. Never fight wind with engine alone if you can use wind and spring to pre-set the angle.

Reefing

When to reef: Before you think you need to. If you're wondering whether to reef, the answer is yes. It is always faster to shake out a reef in lighter wind than to reef in rising conditions. For a Bavaria C42: consider first reef at Force 4–5 apparent (16–20 kn) with inexperienced crew, Force 5–6 (20–25 kn) with experienced crew.

Slab Reefing — Step by Step:

  1. 1Head up slightly to ease the mainsheet and reduce pressure on the sail. Ease the vang/kicker.
  2. 2Ease the main halyard until the reef cringle (the reinforced eyelet at the luff of the reef) is at the level of the boom.
  3. 3Hook the luff cringle onto the reefing hook at the gooseneck (or lead the reefing line through the cringle and secure).
  4. 4Tension the main halyard back up firmly to remove luff wrinkles.
  5. 5Tension the reef pennant (reefing line at the leech) to pull the leech reef cringle down to the boom. This should be very firm — the leech takes the driving force.
  6. 6Tidy the bunt of the sail (the loose material) with sail ties through the reef points. Do not tie tightly around the boom — only around the bunt.
  7. 7Bear away to course and retrim. Adjust vang and mainsheet.

Shaking Out a Reef:

  • Bear away to ease load on sail
  • Ease the reef pennant completely
  • Remove sail ties from the bunt
  • Release the luff cringle from the hook
  • Hoist the halyard to full hoist
  • Retrim and re-tension the vang

Man Overboard — Quick Stop Method

The Quick Stop is the recommended method for short-handed or cruising yachts because it keeps the MOB in sight and the boat close. Practice this — never assume you will remember it under stress.

Immediately
Shout "MAN OVERBOARD"
Press MOB button on chartplotter. Assign one person to point at the MOB continuously — never lose visual contact.
Seconds 1–5
Throw a lifering
Throw the horseshoe lifering with light and drogue immediately. Do not throw it on top of the person.
Step 3
Tack immediately
Head up and tack without releasing the headsail sheet. The headsail backs and slows the boat. You are now on a beam reach on the opposite tack, close to the MOB.
Step 4
Bear away to a reach
Bear away to a beam or broad reach, sailing a small circle around the MOB, keeping them to leeward and in sight.
Step 5
Position to windward
Manoeuvre until you are upwind of the MOB, approaching on a close reach. Drop sails or start engine. Approach slowly with the MOB on the leeward side.
Step 6
Stop alongside MOB
Come alongside with the MOB at the midships shrouds. Stop the boat. Engine in neutral before they are near the prop. Get a line to them and haul them aboard via the swim platform or transom.
If short-handed: Sailing a Quick Stop alone is extremely difficult. Consider using engine only — start engine, drop sails immediately if possible, circle back. The priority is not losing visual contact with the MOB. A single crew member in the water can be impossible to spot after 30 seconds in any swell.

Towing

Whether receiving or giving a tow, the principles are the same: slow speed, even tension, good communication.

  • Tow line length: Match the wave period if possible — both boats should be on the crests or troughs simultaneously (typically 20–40m in calm conditions, longer in swell).
  • Catenary: The sag in the line acts as a shock absorber. Heavy rope (or adding a weight to the middle) increases catenary. Avoid wire or very stiff rope for towing.
  • Attachment on towed vessel: Attach to the mast base or strongest structural point — not just a stern cleat. Use a bridle if possible (both stern cleats to a central point) to distribute load and prevent yawing.
  • Towing speed: Very slow — typically 3–4 knots maximum. At higher speeds the towed vessel surfs forward and creates yawing or overruns the tow.
  • Communication: Agree hand signals or use VHF. The towed vessel is in charge of stopping — one wave = stop / slow down. Make sure both crews understand.
  • Knife: Keep a knife at the helm. If the tow line wraps the prop or the situation deteriorates, you must cut it instantly.

At Anchor Overnight

Anchoring overnight is one of the great pleasures of sailing — and one of the great responsibilities. A dragging anchor in the dark in a crowded anchorage is a serious emergency.

  • Anchor light: Display a white all-round anchor light from the highest practical point (usually the masthead via the steaming light circuit). It is a COLREGS requirement and prevents other vessels anchoring on top of you.
  • Anchor alarm: Set a GPS drag alarm on the chartplotter — radius of 50–100m depending on swing room and conditions. Garmin/Raymarine: mark the position immediately after anchoring, then set alarm.
  • Anchor watch: In poor holding, swell, or crowded anchorage, set hourly checks. At least one crew member should be alert to the alarm — don't all sleep with earplugs in.
  • If you drag: Start engine immediately. Do not attempt to re-set the anchor under power without first knowing where you are relative to other boats and the shore. Motor away from danger, then re-anchor or relocate.
  • Chain and scope: Add more scope if the overnight forecast worsens. It is easier to do this before you go to sleep than at 0200 in 25 knots.
  • Swinging circle: Check again as the wind shifts — an anchorage that was fine with NW wind may leave you awkwardly close to another boat with E wind swing.
