A thorough guide to docking, complete with illustrative diagrams
Returning from an enjoyable journey on the waves, it's now crucial to moor your vessel. A competent captain will stress the importance of efficient docking and securing to maintain your and other boats in prime condition for the next voyage. This guide will navigate you through the process of positioning your boat's lines on the dock, executing the perfect knots, and tips on the essential gear for a secure docking.
Essential Docking Tips
- Position the boat parallel and approximately 1–2 ft (0.30–0.61 m) from the dock.
- Begin by attaching the boat's bow to the dock's cleats or pilings, followed by the stern. Then, connect a spring line from one end of the boat to the opposing dock end.
- For the looped rope end, utilize a simple cleat knot, and for the unlooped end, a cleat hitch. Use a clove hitch for securing lines to pilings.
Docking Procedure
Ensuring Dock Line Security

Navigate the vessel 1–2 feet (0.30–0.61 m) next to the dock or into the slip. Approach at a 20-degree angle in calm conditions, shifting to parallel for an easy step onto the dock. With wind or current aiding, keep parallel throughout, using nature's push to get closer.
- Prepare your lines on the boat cleats and set fenders out before nearing the dock.
- Against wind or current, aim at a sharper 40-degree angle, then halt with reverse thrust before making contact with the dock.
- In a slip, align and gently coast in by alternating forward and neutral gears, using reverse to secure the boat within.

Secure the vessel using bow and stern lines when alongside the dock. Start with the bowline, connecting it from the boat's front cleat to a dock cleat or piling, followed by the stern line at the back. Integrate a spring line for additional stability, weaving through the boat to dock cleats.
- Limit ties to 3-4 cleats to avoid line entanglement. Only use sturdy cleats, avoiding any non-secure fixtures.
- Angle your lines for extra length, accommodating tidal movements.
- If assisted, have your partner secure lines from the dock, managing the spring line until you can tie it off.

For slip dock mooring, use dual bow and stern lines. Begin with two lines at the bow, followed by two at the stern, anchoring them to dock cleats on each side to prevent movement. This configuration stabilizes the boat in the slip.
- Ensure lines are secured to both sides of the dock for firm positioning.
- Be cautious to keep ropes out of the water, avoiding entanglement with the propeller.

Employ breast lines for brief dock proximity. These short lines run directly from the boat to the dock, ideal for quick loading or unloading. They're not meant for long-term mooring as they don't provide the necessary slack for tidal changes, risking the boat's positioning at low tide.
- Ensure the attachment of stern, bow, and spring lines for secure mooring.
- Detach breast lines for extended absences, or adjust to allow more slack by retying from the center cleat to the stern.
Mastering the Art of Knot Tying

Execute a simple cleat knot to fasten the looped end of the rope securely. When dealing with docking ropes, there are typically two ends: a looped one and an unlooped one. To secure the looped end to either the boat or dock cleats, begin by threading the loop beneath and up through the cleat. Proceed by wrapping the loop over the arms of the cleat and gently pulling on the free end of the rope to tighten it.
- If you have someone assisting you by holding the lines but they're not adept at knot tying, instruct them to maintain tension on the rope until you can tie the knot for them. This prevents the boat from drifting away from the dock.

Fasten a cleat hitch to secure the unlooped end of the rope. Pass the line over and around the bottom of the cleat once. Then, slide the line over the top of the cleat and wrap it around the opposite prong of the cleat. Continue by trailing it over the cleat to form a figure 8 shape. Finally, create a small, underhand loop and position it over the first arm of the cleat. Pull the end of the rope to tighten the knot securely.

Utilize a clove hitch when docking at a piling. Envelop the loose end of the line around the post or hook on the piling. Then, cross the line over itself once and loop the loose end around the post again. Thread the loose end under the preceding wrap and pull the loose end of the line to cinch the knot tight.
- Reserve the use of a clove knot solely for attaching to a piling or post. These knots are not suitable for attachment to cleats.
Inspecting Your Docking Equipment

Ensure that your vessel is equipped with cleats on all sides. Cleats typically consist of T-shaped metal fixtures positioned along the sides of the boat, near the edges. Similarly, cleats are affixed to the sides of the dock. Most boats are outfitted with cleats on the bow, stern, and sides to facilitate docking.
- If your boat lacks cleats, consider installing them using thru-bolts accompanied by backing plates. Simply relying on screws to attach the cleats to the deck may result in their detachment under pressure.

Secure your boat to pilings in the absence of dock cleats. Pilings are elongated timber structures extending from the pier or dock. Occasionally, they are equipped with attached cleats. Utilize dock lines and appropriate knots to fasten your boat to a piling in situations where cleats are unavailable.
- Opt for securing your boat to pilings if you anticipate docking for extended periods, as they offer greater stability over time.

Deploy fenders to shield your boat from scratches and impact. Fenders are typically crafted from foam or inflatable rubber materials. They are affixed to the front and sides of your vessel to prevent contact with the pier or dock. Fenders prove invaluable when mooring your boat in a bustling dock environment or when safeguarding its sides from damage while docked.
- Secure fenders to your boat using the attached ties. Keep them stowed inside the boat until docking is imminent, then position them outside the boat before securing the dock lines.

Utilize spring lines to mitigate forward and backward motion. Spring lines are positioned from the rear to the front, or vice versa, of the boat when securing it to a dock. Employ these lines in congested marinas or docks to prevent your boat from drifting forward or backward into neighboring vessels.
Helpful Pointers
-
Secure the boat so that its bow points 20 degrees away from the dock, which helps absorb the impact of minor wakes and waves, thereby preventing the bow from colliding with the dock.
