My original post may be confusing. I will ask it a different way.If you have 2009 or so Sabre, how much clearance do you have between the center roller (the one close to the axle) and the bottom of the boat (the pad/keel)? I would assume this should be an inch or two, and that the roller is only meant to be used when loading the boat. I am not speaking of the rear roller, but the one in the center of the trailer. My trailer also has a “slide” on the front cross member (no issue there).
