I have a 17 ft G3 Boat and when I unload it into the water the bow roller wants to roll to the tip of the boat and then the boat just falls down about 6-8 inches. I am afraid I am going to rip off my new Ultrex I just installed. I tried adjusting the bow rolling up and down and the results are the same. Should I put more of my trailer into the water? or less? I was looking into the Drotto boat latch system. Possibly adding another bow rolling below the original one with a longer arm to support the Keel more. Any opinions?
