Trailering Your Boat This Summer? Avoid These Common Mistakes

Whether you're fishing Puget Sound, exploring the San Juan Islands, or spending the weekend at your favorite lake, trailering your boat offers flexibility and adventure.

Unfortunately, it can also introduce risks that many boat owners overlook.

Before you hit the road this summer, take a few minutes to review these common trailering mistakes—and how to avoid them.

1. Skipping a Trailer Inspection

Your boat may be ready for the season, but what about the trailer?

After months of storage, it's important to inspect your trailer before your first trip. Check tire pressure and tread, test all lights and signals, inspect wheel bearings, verify brakes are functioning properly, and look for signs of rust or corrosion.

A trailer breakdown can quickly turn a relaxing weekend into a stressful and expensive experience.

2. Overlooking Tire Maintenance

Trailer tires often age out before they wear out.

Even if your tires appear to have plenty of tread, exposure to sunlight, moisture, and changing temperatures can weaken the rubber over time. Inspect for cracking, dry rot, bulges, or uneven wear before every trip.

Don't forget to check your spare tire, too. Many boat owners discover their spare isn't usable only after a flat tire occurs.

3. Improperly Securing the Boat

One of the most common mistakes is assuming the winch strap alone will keep the boat secure.

Always use properly rated transom straps and safety chains in addition to the winch. Double-check that all tie-downs are tight and secure before leaving and periodically during longer trips.

A shifting boat can damage both the vessel and trailer—or create a serious hazard for other drivers.

4. Forgetting to Check Weight Limits

Every trailer, tow vehicle, and hitch has a maximum weight rating.

Before heading out, make sure you understand the combined weight of your boat, trailer, fuel, gear, coolers, and equipment. Exceeding weight limits can affect handling, braking performance, and overall safety.

If you've added electronics, fishing gear, or other upgrades over the years, your boat may weigh more than you realize.

5. Ignoring Trailer Bearings

Wheel bearing failures are one of the leading causes of trailer breakdowns.

Bearings should be regularly inspected, cleaned, and lubricated according to the manufacturer's recommendations. Heat buildup, water intrusion, and lack of maintenance can quickly lead to costly failures.

A quick inspection before the season can save you from being stranded on the side of the road.

6. Launching Without a Pre-Launch Checklist

The excitement of getting on the water can make it easy to miss important steps.

Before backing down the ramp, verify that:

  • Drain plugs are installed
  • Battery switches are on
  • Fuel levels are adequate
  • Safety equipment is onboard
  • Dock lines and fenders are ready

A simple checklist can help prevent embarrassing—and sometimes expensive—mistakes at the launch ramp.

7. Assuming Your Insurance Covers Every Situation

Many boat owners don't realize that coverage can vary depending on the circumstances of a loss.

For example, damage that occurs while your boat is being transported, trailer-related incidents, or liability situations involving the trailer may be handled differently depending on your policies and coverages.

That's why it's a good idea to review your marine insurance coverage before boating season gets into full swing. Understanding how your vessel, trailer, and towing exposures are insured can help eliminate surprises later.

Enjoy the Journey to the Water

Trailering your boat safely isn't just about protecting your investment, it's about protecting your summer plans.

A little preparation before each trip can help you avoid breakdowns, prevent damage, and spend more time doing what you enjoy most: being on the water.
