I had this exact thing happen to me once – I pulled the trailer out about 6 inches and tried again, and it worked as advertised. The bunks have to be out of the water enough to set the hull at the correct angle to go above the front roller, with the hull predominantly on the bunks. I also fish alone most times, so it helps getting it right first time, embarrassing to me if I don’t. I got the boat just last summer. It does feel good when I can get in and out by myself in less time than when someone else on the ramp struggles, though I prefer to be without spectators if I mess up, or keep people waiting.
I think the Caracal doesn’t load well if the trailer is too deep, esp in rough water. I had it once under the front roller, and once where it was cockeyed on the bunks, not straight. Both were cases of the trailer being too deep.
I back in so that the bunks are all wet, then pull back out until the top of the wheel fairing is out of the water, and the top of that back slope of the top of the fairing is just curving in. As described above, though I can’t see it when backing in, this generally equates to the short, inner bunks 1-2 inches out of the water, depending on ramps slope. It takes some juice on the motor (motor tilted as described above) to get it all the way up, but it works – once I feel the hard stop of the front roller, I know I’m there.
Only one time did I not have the trailer deep enough, and no matter how much I throttled up, that thing didn’t move past a certain point. It’s heavy. Had to back in a bit more and try again, then it worked. But that is easier to gauge than too deep.
