trailer & boat
You have the same questions I had about 3 months ago. I have a capri22 fin keel boat and was having trouble getting the boat to stay on bow stop. Here is what I did. Position the trailer winch so that it is basically horizontal with bow eye on boat when boat is on trailer. I made a double bow stop (buy steel straps from home depot) that the boat will touch above and below winch/bow eye horizontal location. The key is that the double bow stop pivots at the center which is the same horizontal position as the winch. Check out some of the J22 type EZ loader trailers ---they have this double bow stop. The nice thing about this is as you winch the boat tight against the bow stop, the stop will rotate as the boat rotates to sit on trailer. But again everything must be centered (same horizontal plane) about the bow eye on trailer.Back trailer into water so bow eye is near the horizontal position of winch. Winch boat tight.Pull boat out. Sometimes you can use the front of your pads/bunks to get the bow of the boat in the correct position relative to the trailer winch. hope this helps.Also, Here is a response from the J22 forum on when I posted the same question.The problem I think you are having is the attachment point on the boat and the winch location are not at equal angles when the trailer is floated vs. when the boat is properly on the trailer. You float the boat on, tighten it up and when you pull out, the angles change and the bow is now not where it was. Ideally, what you want is the attachment point to be snug on the support at most reasonable angles. It needs to be a pivot point where independant of the angle, the distance is equal. It may require adjusting your support or the attachment point on the boat. On my trailer, my attachement is a bow eye about 1 ft below the bow. The support is an articulating dual pad/bumper and the eye is winched between these pads. As the boat is pulled out, the pads rotate with the bow. Everything stays tight because the angle of pull is unchanged. My trailer is an EZLoader and this is standard on them, I think. On trailer depth, back it down until the support is at the right height above the water for the boat to just float to there, then tie it down. Remeber that when you go forward on the boat, the bow will dig in about 6 inches. Really doesn't require a winch, but they work fine for this.
