The way the trailer fits in the back is more critical. Most of the weight in modern pontoons in in the stern. The captain’s helm, gas tanks, the engine, etc. The back of the tubes should not extend much more than a foot beyond the back of the trailer. The images to the left show a good fit. The image on the far right shows a boat with 3+’ of overhang. This will affect the balance on the trailer and result in too little tongue weight. In the picture you can see how the front of the trailer seems tilted up.
|Our trailers are fully adjustable. Older boats were 8’ wide and are usually on 72” centers. Newer boats (after about 2008) are often 8’6” wide and are usually adjusted to 77” centers. But there is no exact dimension for all brands. The rule of thumb is 72” and 77” but for a perfect fit you should measure the center to center distance. It’s just a ten minute job to move the carpeted bunks, but its easier to do with power tools at the manufacturer or dealership.|
|It’s possible to use some trailers for various length pontoons. By sliding the winch stand forward or back you have about 2’ of adjustability. The same trailer frame can fit a 18-21’ or 22’-24’ boat. You must be careful when moving the winch stand back to make sure you maintain proper tongue weight.|
|The strength of the winch stand is in the center of the support arms. The front of the pontoon should rest as closely to the center as possible. These front arms take considerable force when you come in fast. This is called power loading. On a good ramp you drive your boat all the way onto the trailer. If you don’t throttle back you can actually damage the winch stand and the front of the boat. Never boats have larger diameter pontoons. Some trailer manufacturers still use winch stands designed for 23” diameter pontoons on 25” or 27” diameter pontoons. Make sure the winch stand is the proper height for your pontoons. Most manufacturers won’t offer you any warranty relief if you damage their stand. In our opinion companies that use short stands on big pontoons have a design defect, but again it will be your problem, not the trailer builder.|
|Below is an example of a poorly fitted trailer.|
|Unfortunately its one we sold. The customer told us he had a 23’ pontoon and we set up the trailer to fit. Unfortunately when he got the boat on the trailer he discovered his pontoon was a 20’ pontoon. Fortunately he was only a couple hours away and we were able to swap out trailers, but this is a example of why getting the proper information allows us to help you a perfect fit.|
