The swing beam boat trailer range has been designed to be the best trailer for slipway and beach launching. The trailer has no centre keel rollers, but instead has swinging beams with large banks of rollers to support the boat down the sides of the hull. This makes loading and unloading the boat a lot easier even in shallow water. The side rollers are adjustable sideways and up and down so they can easily be set up to suit most hull designs. The chassis is totally welded and hot dipped galvanized. The adjustable draw bar allows the length of the trailer to be altered to suit the length of boat. The draw bar can be removed when storing the boat and trailer in a garage.
