I JUST GOT ANOTHER BOAT THAT HAS A ROLLER/ TILT TRAILER AND I AM NOT SURE HOW THIS WORKS. THE FIRST TIME I LAUNCHED THIS 21' CABIN CRUISER IT SLID( ROLLED) OFF THE TRAILER HIT THE RAMP TWICE AND SPLASHED DOWN AT DOCK SIDE! IT WAS SUCCESFUL IN THE FACT NOTHING HAPPENED TO THE BOAT AND IT CONINUED TO FLOAT AND WE WENT FISHING. LOADING IT WAS JUST AS GREAT. THE WINCH STRAP BROKE AS I PULLED OUT OF THE WATER AND UP THE RAMP, GOOD THING THE CHAIN WAS ON. HOW DOES THIS TRAILER WORK AND HOW DO I KEEP THE BOAT FROM ROLLING OFF WHILE I DRIVE UP A HILL??CAN I LOCK THE ROLLERS??
- hELp!!!
