Picking up a mooring ball looks easy when an experienced crew does it: the boat glides up, someone at the bow reaches down with a boat hook, and a minute later the lines are on the cleats. The first few times you try it, though, the ball tends to disappear under the bow, the boat drifts off, and somebody ends up lying on the foredeck with an arm in the water.

Quick answer: to pick up a mooring ball, prepare two bow lines and a boat hook, approach slowly heading into whatever is moving the boat most (wind or current), let the bow crew point continuously at the ball, stop with the ball just off the bow, hook the pennant or pickup float, and make fast with a two-line bridle led through separate fairleads. If you miss, back off, circle round and try again.

This guide covers the technique step by step, including how to do it single-handed and how to secure the boat so it is still there in the morning. If you are still deciding whether to keep your boat on a mooring at all, see our comparison of mooring ball vs slip. For berthing stern-to a quay instead, see our guide to Med mooring.

Before You Approach: Plan and Inspect

Most failed pickups are lost before the boat gets anywhere near the ball. Do the planning while you are still well clear of the mooring field.

• Find out which mooring you can use. In many harbors moorings are private, assigned by a harbormaster or launch service, or color-coded for visitors. Call on the VHF or check the cruising guide rather than grabbing the first empty ball.
• Check the size rating. This is especially important on a bareboat charter, where you are in an unfamiliar harbor. Rental and municipal moorings are often marked with a maximum boat length or weight. A mooring sized for a 25-foot day boat is not safe for a 45-foot cruiser in a blow.
• Look at the hardware. Note whether the ball has a pennant (a rope loop on a small pickup float), a ring or shackle on top, or a long pickup stick. This tells you what you will be hooking and whether you will need to thread your own lines.
• Rig your gear. Prepare two bow lines, each made fast to its own bow cleat and led out through the fairlead or bow roller, coiled ready. Have a boat hook on the foredeck, and fenders handy in case the field is tight.
• Brief the crew. Decide who is on the helm, who is on the bow, which side you will pick up the ball on, and what the signals are (see below).

Drop or furl the sails and motor in. Picking up a mooring under sail is a good skill to have, but under power you have brakes, which matters a lot when you are learning.

Approaching Into Wind or Current

The golden rule is to make your final approach heading into whatever is affecting the boat most, usually the wind, but in tidal harbors and rivers it is often the current. Approaching from downwind or down-current means the elements slow you down and you can stop precisely with minimal throttle. Approaching with the wind behind you means the boat keeps going after you hook the ball, and the pennant gets ripped out of your crew’s hand.

The easiest way to read the conditions is to look at boats already moored. They lie with their bows pointing into the stronger of wind or current, so line up your approach parallel to them, heading the same way.

1. Make a slow pass through the field to identify the ball and the hazards around it.
2. Circle round to a point several boat lengths downwind or down-current of the ball.
3. Turn to head straight at it, in line with the moored boats, at dead slow: just enough speed to steer.
4. Aim to stop with the ball near the bow on the pickup side, not under the middle of the bow where the bow crew cannot reach it and the helm cannot see it.
5. As the boat loses way, shift to neutral, and use a short burst of reverse if needed to stop completely.

Know which way your stern swings in reverse before you do this (see our guide to prop walk). On most boats with a right-handed propeller the stern kicks to port, so a touch of reverse will also swing the bow to starboard. Many skippers deliberately pick up the ball on the side that works with their prop walk. Our guide to sailing maneuvers and docking has more on boat handling at low speed.

Crew Roles and Hand Signals

The helm loses sight of the ball when it is still a boat length or two away, so the bow crew becomes the helm’s eyes. Shouting into the wind rarely works; simple hand signals do.

Signal	Meaning
Arm pointing at the ball	Steer this way. Keep pointing continuously, all the way in.
Hand held up, palm forward	Slow down or stop.
Thumb pointing back over the shoulder	Give a little reverse.
Hand waving forward	Come ahead slowly.
Thumbs up / clenched fist	Got it, the line is secure.
Arms crossed or waving off	Missed it, abort and go around.

Agree on the signals before the approach and keep them consistent. On a larger boat a headset system or handheld radio helps, but signals are still worth knowing as a backup. For more on who does what on deck, see our guide to sailing crew roles.

Using a Boat Hook and the Pennant

When the ball is alongside the bow, the bow crew hooks the pennant loop, the pickup float or the pickup stick, and lifts it to deck level. A few points make this much easier:

• Hook the pennant under the float rather than stabbing at the ball itself. The ball is heavy and attached to chain; the pennant is what you want.
• Lift, do not pull. The crew should not try to hold the boat against the wind with the boat hook. If the boat is drifting back, let the hook go, call for a little forward throttle, and try again.
• Get a line on fast. Drop the pennant eye over a cleat, or pass one of your bow lines through the mooring eye, then sort out the final arrangement once the boat is held.
• Never put hands or feet between the line and the hull, cleat or bow roller while the boat is surging back.

Boats with a high bow and moorings with no pennant (just a ring on top of the ball) are a common problem in the Mediterranean and Caribbean. Options include a mooring hook on a pole that clips a line straight into the ring, or picking up the ball from the lower side deck amidships and then walking the line forward outside everything to the bow.

Picking Up a Mooring Single-Handed

Sailing alone, you cannot be at the bow and the helm at the same time, so pick up the ball where you can reach it from the helm or close to it: at the stern quarter or amidships, where the freeboard is low.

1. Prepare a long line made fast to a bow cleat, led outside the stanchions, shrouds and everything else, back to the cockpit or midships cleat.
2. Approach into the wind or current as usual, but bring the ball alongside the midships or quarter on the side you have rigged.
3. Stop the boat, hook the pennant or pass your line through the ring, and make the end fast to the midships cleat temporarily.
4. Put the engine in neutral. The boat will fall back and pivot so the bow swings toward the mooring.
5. Walk forward, take up the slack and secure properly at the bow, then add the second bow line.

This method works with the boat’s natural tendency rather than against it, and you never have to run from the helm to the bow while the boat drifts. Our guide to single-handed sailing covers more shorthanded techniques.

Securing the Boat: Bridles and Chafe

Getting hold of the ball is half the job. How you tie up decides whether the boat lies quietly or saws through its lines overnight.

Use two lines through separate fairleads

The most secure setup is a two-line bridle: one line from the port bow cleat and one from the starboard bow cleat, each led through its own fairlead or chock, through the mooring eye and back to the same cleat it came from. Two lines share the load, give redundancy if one chafes, and stop the boat from sailing around the ball as much as a single line would.

Avoid running a single line through the eye and back to the other cleat. When the boat swings, that line saws back and forth through the eye and can wear through surprisingly quickly. Likewise, never cleat a line taken through the ring onto itself in a way that lets it slide.

Pennant or your own lines?

If the mooring has a pennant in good condition and sized for your boat, it is usually fine to drop the eye over a bow cleat, and many harbors expect you to. If it looks old, frayed or undersized, use your own lines as well or instead, led through the hard eye on the ball or chain.

Prevent chafe

• Make sure lines run fair through fairleads, not over sharp edges, the anchor, or the stemhead fitting.
• Add chafe guards (split hose or purpose-made sleeves) where lines cross the fairleads, especially if wind is forecast.
• Leave the eye about a meter or so in front of the bow, so the ball does not bang the hull at night but the boat cannot range too far.
• Check the lines and the anchor (lashed so it cannot drop) before going ashore and again if the wind picks up.

If a strong wind or swell is forecast and you are unsure about the mooring, it may be safer to leave and anchor properly instead. Our step-by-step guide on how to anchor a sailboat covers that.

Leaving a Mooring

Leaving is usually simpler, but it still needs a plan, especially in a crowded field or with a dinghy in tow.

1. Start the engine and let it warm up. Check that no lines, including the dinghy painter, are in the water near the propeller.
2. Remove one bow line and convert the other into a slip line, led through the eye and back aboard so it can be released from the deck.
3. Motor gently forward to take the load off the line, then the bow crew slips it and pulls it in fast, calling “free” when it is aboard.
4. Let the boat fall back or steer away to one side, keeping clear of the ball and its chain. Do not drive over the ball.
5. Once clear, pull the dinghy painter short or lift the dinghy before heading out through the field.

If you are towing a tender, take care it does not foul the mooring pennant as you leave. Our guide to towing a dinghy behind a sailboat explains how to set up the tow.

Common Mistakes

• Approaching downwind or across the current, so the boat cannot be stopped.
• Coming in too fast, then using a big burst of reverse that spins the stern sideways.
• Bow crew holding the boat on the boat hook instead of letting go and asking for throttle.
• Losing sight of the ball and running over it, which risks fouling the prop on the pennant.
• Using a single line through the eye, which chafes through.
• Tying up to a private or undersized mooring without asking.

How to Pick Up a Mooring Ball: Summary

Prepare two bow lines and a boat hook, read the moored boats to find the direction of wind and current, and approach slowly heading into it. Let the bow crew point continuously at the ball, stop the boat with the engine rather than the boat hook, and secure with a two-line bridle through separate fairleads with chafe protection. Single-handers should pick up the ball near the stern or midships and walk the line forward. And if it does not work the first time, go around: nobody watching thinks less of a skipper who makes a second, controlled approach.
