The centre keel roller boat trailer range has been designed to give the boat the maximum amount of support, but still allowing easy lunch and recovery.The totally welded hot dipped galvanised chassis incorporates the adjustable draw bar which allows the length of the trailer to be altered to suit the size of boat. The draw bar can be removed when storing the boat and trailer in a garage. The centre keel rollers support the boats keel and the side rollers are adjustable sideways and up and down so it can easily be set to suit most hull designs. All centre keel boat trailers can be fitted with side support carpeted side bunks instead of the rollers.
