Our Top Dos and Don’ts For Buying a Boat Trailer 


After all the dreaming and the research, you have finally bought what’s probably your second largest investment, next to your home; a boat. Congratulations! The focus now turns to the most essential accessory, the trailer. Now we can be honest, boat trailers are not sexy (unlike the boat), however they are a type of insurance for your prized possession. Choosing the right trailer and trailer set up will guarantee that your boat is well-protected while being towed. It also makes the launching and retrieval process of your boat stress-free. You can spend more time creating enjoyable family memories, rather than worrying about your boat on an ill-fitted trailer. Here are our top do’s and don’ts for purchasing a boat trailer.


Do: Ensure your trailer is the right length

For your first consideration, you must ensure your trailer is the right length for your boat. This is calculated on the true hull length. Boat manufacturers usually have this listed in their specifications online, however you can also grab a tape measure and measure for yourself. Simply measure from the bow sprite to the transom, and do not include swim platform in your measurements.


Do: Know the weight of your boat

Every boat trailer has a maximum weight rating that determines the trailer’s capacity to correctly support your vessel. There is also the BMT (Boat Motor Trailer capacity) to consider. This BMT includes the total weight of the boat, motor, trailer, not just its dry weight. When making your trailer purchase, you must always consider the weight within the boat, such as fuel, water, oil, safety equipment, anchor and all other contents as this is incorporated into the BMT capacity.

Do: Choose the right axle

This boat trailer consideration is dependent on the size/weight of your boat and in what capacity and distance you will be towing your trailer. Smaller, light weight boats only require a single axle trailer. Single axle boat trailers, below 750kg are not required by law to have brakes, so this can be a consideration regarding safety if you are in that mid weight/size category where it becomes a personal choice for single or dual axle. Dual and tri axle boat trailers help disperse the weight load across each axle, therefore providing more stability, less bounce and less sway under tow, therefore being advantageous to long distance/highway driving.


Do: Have a Boat Fitting

Correct boat fitting extends the life of your boat and trailer. Do not risk an ill-fitted trailer when towing. This can cause expensive damage to your boat. Reputable trailer manufacturers will have overhead gantries, drive on scales, experience and equipment to snuggly, safely and correctly fit your boat to your trailer. Well worth the investment. This correct fitting should also ensure launching and retrieving your boat and overall boat ramp experience is carefree and stress-free.
