When Should You Put Fenders on A Boat?

Proper use of marine fenders is essential to protect your boat from damage during docking and mooring. However, knowing exactly when to put fenders on a boat can significantly improve their effectiveness and ensure safer, smoother operations. In this article, we will guide you through the best timing and conditions for deploying boat fenders, helping you safeguard your vessel, reduce repair costs, and enhance your overall boating experience.

Why Timing Matters When Deploying Boat Fenders

Fenders serve as cushions between your boat and docks, pilings, or other vessels. Deploying them at the right moment ensures their protective effect is maximized. Too late, and your boat might sustain damage during contact; too early, and you may encounter unnecessary hassle or risk fouling lines.

In addition, proper timing is a key part of safe boating practices. Effective fender use contributes to:

Minimizing hull scratches, dents, and structural damage.

Avoiding costly repairs and maintenance.

Enhancing crew confidence and operational safety.

Prolonging the lifespan of both your boat and dock infrastructure.

Understanding the best moments to put fenders on will help you achieve these benefits every time you dock or moor.

When Do You Need to Put Fenders on Your Boat During Docking?

Before approaching the dock, it’s crucial to prepare your fenders in advance. Ideally, you should:

Attach and position fenders before getting too close to the dock.

Ensure fenders are adjusted to the appropriate height relative to the dock surface.

Position fenders along areas most likely to contact the dock — usually midship and near the bow and stern.

Different dock types and conditions influence when and how many fenders you need. For example:

Marinas with floating docks may require fenders set slightly lower to protect against tidal movement.

Fixed piers often necessitate more fenders along the hull due to harder surfaces.

Crowded harbors or busy shipyards might require additional fenders on both sides to prevent contact with multiple vessels.

By preparing your fenders properly and early, you reduce the chance of last-minute mishaps during the final approach.

In addition, when approaching a dock, having fenders deployed on both sides can be beneficial. This precaution protects your vessel against unexpected lateral movements caused by wind, current, or waves. It also ensures that if the boat swings slightly during the mooring process, there is always a buffer to prevent damage.

Should Fenders Be Deployed While the Boat Is Underway or Anchored?

While underway (i.e., moving), it is generally not necessary or recommended to deploy fenders, as they may:

Drag in the water, causing damage to the fender or hull.

Get caught on underwater obstacles or other vessels.

Hinder maneuverability and create unnecessary drag.

Therefore, fenders are best stowed securely while the boat is cruising or maneuvering in open water.

However, as you slow down and prepare to dock, deploy the fenders well before the boat comes close to any structure. This proactive approach minimizes risk during the critical moments of docking.

When anchored in calm waters away from docks or other boats, fenders typically aren’t needed unless you anticipate close contact with other vessels or floating debris. In crowded anchorage areas or where wind and current may push boats together, fenders can provide additional safety margins. This is especially true for larger vessels or boats with sensitive hull coatings, where even gentle contact could cause harm.

How Does Weather and Tide Influence When to Use Fenders?

Weather conditions and tides significantly affect the timing and need for fender deployment:

Windy or choppy conditions increase the risk of sudden impacts or boat movement, so deploying fenders earlier and adding extra protection is advised.

Tidal changes affect the relative height between your boat and dock, requiring fenders to be adjusted or repositioned to maintain effective cushioning.

Strong currents or river flows may push your boat unpredictably against the dock or other vessels, making timely fender use critical.

Ignoring these environmental factors can result in collisions that cause damage to both the vessel and the dock, as well as potential safety hazards for passengers and crew.

For example, in tidal areas where the dock height changes significantly with the tide, a fender set too high or too low can fail to protect the hull effectively. To address this, some boat owners install adjustable fender systems or use multiple fenders of different sizes to accommodate tidal variation.

Similarly, if you are docking in a harbor known for gusty winds, it is prudent to add additional fenders and deploy them sooner than usual. This precaution helps absorb unexpected impacts caused by sudden boat movement.

What Are the Risks of Not Using Fenders at the Right Time?

Neglecting to deploy fenders correctly or on time exposes your boat to several risks:

Physical damage such as scratches, dents, and cracks to the hull and superstructure.

Damage to dock facilities, which may lead to liability and additional repair costs.

Increased maintenance and repair expenses, cutting into your boating budget.

Safety hazards for crew and passengers during docking operations.

Reduced vessel resale value due to visible or structural damage.

Improper or delayed fender use can also lead to operational delays, increased stress for the crew, and a higher likelihood of accidents during docking and mooring.

Moreover, excessive or improperly placed fenders can create their own problems, such as fouling ropes, obstructing crew movement, or even trapping water between the fender and hull, leading to corrosion over time.

Finding the right balance and deploying fenders at the correct time helps avoid these issues and ensures a smoother, safer docking process.

Conclusion

Using marine fenders at the right time is crucial to protect your boat and dock from damage and to ensure safe, efficient berthing. Preparing and deploying fenders before docking, adjusting them according to environmental conditions such as tide and weather, and understanding when not to use them while underway or anchored all contribute to optimal vessel protection. Failing to time fender deployment correctly can lead to costly repairs and safety hazards. For the best results, boat owners should plan fender placement in advance, maintain their equipment regularly, and consider professional advice tailored to their specific boat type and berthing environment.
