We currently own a 1998 Four Winns Horizon QX with a fairly standard trailer, just before you ask... there are no breaks on the trailer.<br /><br />We've owned the boat for around 2 weeks now so are very new to the whole boating experience. When trailering our boat to the launch ramp we have noticed some shunting back and forward. The movement is not noticable while accelerating or traveling up a hill. I've checked the ball size and that matches, plus it seems a pretty tight fit.<br /><br />Maybe I'm just confused and this is normal, if so please let me know.. If not please let me know if any of you have experienced similar things or know what the problem is.<br /><br />thanks<br /><br />Craig.
