If you own a boat, you likely need a boat trailer at some point to allow you to tow your boat with your vehicle. There are a plethora of choices at your disposal. Those with smaller boats may want to go with a single axle boat trailer, but those with moderate to large boats might need to utilise a twin axle boat trailer.
One Axle vs. Two
One axle is sufficient if you are hauling a smaller vessel. However, you should consider getting a dual axle trailer for a larger boat. The reason for this is that the extra axle eliminates any swaying that may take place while transporting the boat. It is for this reason that you may also want to consider a twin axle trailer if you plan on going on any long trips with your boat, regardless of the boat's size.
Know the Specifications
Make absolutely sure you know the maximum load weight of the trailer you are planning on buying. Also make sure your vehicle is strong enough to haul the boat along with the trailer. It only takes a few moments to verify this information and failing to do so can lead to a potentially dangerous situation.
Loading a Boat onto the Trailer
Before anything else, you need to make sure you have a ramp for your trailer. If you load your boat from the water, then pilot it towards the ramp. If you load the boat from land, then back your vehicle toward the front of the boat and fasten the winch line to the bow. Depending on the type of winch, you may need to use a hand crank to bring the boat onto the trailer. At this point, all you need to do is fasten the boat down.
Attaching the Trailer to the Vehicle
First, you need to make sure your parking brake is set. It is also good practice to jack your car up a bit so you have as much clearance as necessary. If your vehicle can already accept hitch mounts, then simply attach the hitch. However, if your vehicle cannot accept mounts, then you have to drill holes into the frame, which requires a capable drill, some screws, and a C-clamp. Once the mount is attached, use the C-clamp to help further attach and bolt it to the vehicle.
