    Boat trailer for my 185 Bayliner - very rough on boat whepassing over road bumps-gctid802619

    Hi, I have a 2005 18.5 foot Bayliner that came with a single axis trailer and carpeted boards. So here is my problem.

    My trailer is very rough on my boat when I cross over road bumps.

    When I go over speed bumps or any bump for that matter with the boat on the trailer it makes a terrible noise like the boat is going to come off the trailer. I double check that the boat straps are properly snugged to the trailer but it still sounds like the boat is taking quite a shock when driving the trailer over bumps. The supporting boards also look good and the boat is fully rested on the boards.

    I wondered if others had similar experiences with their single axis trailers. It just seems like the trailer springs are so stiff that all the energy is transferred to the boat. Almost like not having springs. Does anyone have any recommendations. I am getting ready for a long trip and want to resolve this problem.

    Thanks ahead of time.

    Could be the slop in the ball mount to receiver your hearing. My 1800 sat on a single axle as well, it too was noisy over speed bumps etc, never hurt the boat any

      Sky, if this trailer has a single torsion axle, that may explain the rough ride.

      Torsion axles suspensions do not offer the smooth action as found in leaf spring suspensions.

          With the trailer off the truck, put the receiver in and shake it. If your hitch has a lot of play from being old and used that might be it. Then put the ball under the hitch and latch it not hooked to the truck. See if there is play in the coupler. If there is there is a nut on the bottom of the coupler that can be tightened.

            I have a torsion axle trailer for my 13' Boston Whaler. It bounces quite a bit over bumps. There's not much that can be done about it.

              At one time my boat seemed to bounce more than usual. It turns out that the bow was not resting on the trailer's bow roller property. What was happening was that the boat would bounce up and back down on the bunks every time the trailer hit a rough part of the road. It probably only lifted about an inch or two. But that was enough to hear and feel the banging. Having towed the boat previously, I knew right away that there was something not right.

                Check your tongue weight. If there is not enough it will try to lift the hitch off the ball.

                Also make sure the front of the boat is snugged into the bowreat as suggested. I like to add a ratchet strap in support of the winch dog to extend its life and have a backup besides the last resort chain

                  The boat's hull should become part of the triangulation; I.E., the portion where the bunks support the hull, an imaginary angled line from the stern up to the bow eye and winch tower's attachment point, and then back down to the main frame.

                  When this is tight, you should be able to invision triangulation. [/color]

                    Also check your trailer. My friend has double rollers like this one. She knows everything, and had the cable line go over the top of the top roller. Her boat was on the trailer but back to far. After I found the problem she had no problems towing. The cable should go in the middle of the rollers if you have one like this.

                      Good point about the ball mount. I will check it.

                        I have leaf springs. I ended up writing the trailer manufacture today for some ideas and suggestions also.

                        Many thanks

                          Funny, we have had many boats but the wife wanted to downsize. I still expect certain standards however. I like the boat and it has performed well over the years except for some gage problems and a slave solenoid I had to replace.

                          Cheers and thanks

                            All good ideas, I will check. I have checked all the rest except for the mount so I will do that soon.

                            Thanks

                              I will make sure the supports and the bow is resting on the roller. Thanks for the ideas.
