I am having an awful time getting my Catalina 250 all the way on my trailer properly. I have had to resort to using a come-along. The wing keel hits the floor of the trailer too soon or the trailer is in too far and I have problems with the bow pulpit.
Are you using a strap or rope to get the trailer in far enough? We put the trailer out far enough so that the pads are about 4"-6" below the surface. I have a line tied to the trailer's mast tower and I stand on the boat bow and use that line to pull/float the boat onto the trailer. Then I attach the trailer winch strap to the bow eye and tighten it. The keel is not on the "floor" or the pads at that point. As the trailer is pulled forward the boat/keel settles down on the keel and pads. I have the driver stop every few feet so that I can keep the winch/eye strap tight as the boat settles. If you keep the strap tight it stops the boat from moving back.
Note how the winch strap is routed. Attach it this way and as the boat settles the strap will be correctly routed.
In addition to what has been posted, check to see if the trailer rails along the keel are too close together and are pinching the keel. When I picked my boat up, I couldn't get the boat all the way on the trailer. The rails had shifted, were pinching the keel and holding the boat back. Once I loosened the rails I could move the boat all the way onto the trailer.
