Four Tips for Buying a Used Boat Trailer

As the boating season ends in the northern climates, some boaters may be looking to find a trailer to store the boat for the winter. If you’re looking to buy a used boat trailer now or planning on buying a boat that comes with a used trailer, Boat Owners Association of The United States (BoatUS) has four buying tips:

Bring a measuring tape: With older trailers, the capacity plate or sticker may be long gone or too hard to read after being outside in the weather for years. But if you’d like to know a rough idea of a spring-axle trailer’s capacity, simply measure the diameter of the axle. An outer diameter (OD) axle tube size of 1.75” is typically rated for about one ton; 2.375” for 3,500 lbs.; and 3” for 5,200-7,000 lbs. – remember to subtract the weight of the trailer from the gross capacity.

Buying out of state: Trailers aren’t built the same because states’ trailering regulations aren’t the same. While most states require brakes for trailers rated to carry than more than 3,000 lbs., some states require brakes on trailers as light as 1,500 lbs., while a few others let you coast up to 4,500 pounds – although that’s not recommended. It can be expensive to retrofit brakes, and some states such as Florida require brakes on each axle. State-specific trailer registration information can be found at drivinglaws.aaa.com.

Why tire diameter matters: After an hour at highway speeds, a 13-inch tire will have spun 10,000 revolutions more than a 15-inch tire, which means more heat, bearing wear and increased chance of problems. Having a fully serviced spare tire ready to go – and the tools to install it – will solve many of the most common reasons for a trailer breakdown. If all else fails, having an annual BoatUS membership with Unlimited Trailer Assist roadside assistance to safely tow both your boat trailer and tow vehicle up to a 100 miles will make a bad roadside breakdown suddenly get much better.

Watch out for paperwork snafus: Not having ownership documents can sink a sale faster than you can say, “Did you put the plug in?” If the trailer is missing the vehicle identification number (VIN), it cannot be legibly read or doesn’t match ownership paperwork, you may run into an issue with the DMV and have to apply for a replacement. It’s better to have the seller handle this before the sale.

Boater’s Guide To Winterizing

Water expands in volume by about nine percent when it freezes, creating a staggering force that can crack a boat engine block, damage fiberglass, split hoses, or destroy a boat’s refrigeration system overnight. As cold weather approaches, Boat Owners Association of The United States (BoatUS) dug into its claims data and found that more than three-quarters of winter-related claims involved cracks in the engine block or the exhaust manifolds. Now, the national boating services, safety and advocacy group has available at no-cost a 15-page “Boater's Guide to Winterizing” that can ensure boaters don’t miss a step for any type of boat.

“Boaters up North know they need to winterize, so their freeze claims almost always involve poor winterizing,” said BoatUS Director of Technical Services Beth Leonard. “In the temperate South, the issue can be a case of no winterizing, or relying on a heater when the electricity goes off, usually when you need it most.”

The downloadable brochure addresses the reasons for more than 95 percent of the freeze claims handled by the BoatUS Marine Insurance Program in the past decade. Included are chapters on: Storing your boat - The options and the tradeoffs; a Winterizing Checklist to use as the starting point for creating your own boat’s winterizing list; Engines and Drives - The dos and don’ts; and Plumbing - Getting the water out, which is great for larger boats.

Additional information includes tips on choosing antifreeze, lessons learned from BoatUS Consumer Affairs about protecting yourself with a winterization contract, and green winterizing information.
