Something to consider, and this is just MHO..........based on my XB2003 and how it originally sat on the trailer. The boat, with 13.5" setback and a 2.5 liter motor, sat very "nose high" in relation to the bow stop roller. I always believed that for it to be "right", the bow should have just touched or rested on that bow roller WITHOUT having to apply quite a bit of downward pressure with a turnbuckle etc, to get it there. These boats, trailers, may not all be the same and I realize that, but with mine, the bow was easily 1" - 1.5" above the roller without cranking down on it. When enough pressure was applied to it to pull it down, you could see the trailer flexing as the bottom of the boat was forced down onto it. I never thought that was a good idea. The old style bow eye that I had would become "chewed up" quickly from that pressure. I had replaced the bow eye several times. My "fix" was to replace the 2 upright bunks with bunks that were higher in the rear than in the front so the boat would be angled down more allowing the nose of the boat to just barely contact the roller without having to apply great force to pull it down. I also replaced the old style bow eye with one that doesn't have the "fancy chrome" covering it that so quickly was destroyed. Just sharing this for what it may be worth. My boat is now no longer forced down onto the 2 lower v bunks that were never intended to support the hull, but were there for guiding the boat when loading it onto the trailer. I use only a rather small chain then from the winch stand with a hook on the end of it that easily goes through the different style bow eye. Although my chain does then attach to the bow eye, it allows the boat to only move back a few inches. It becomes just a safety precaution in case the winch strap for some reason wouldn't hold the boat in the loaded position.
