Time for some maintenance and repairs....all of us boat owners have had those days ! Over many years of experience I have learned to take the time, spend the money, and do it right ! Pays off in the long run. The only thing I can address here is your boat going on crooked. With all the gizmos we have today, there is no excuse to have your boat on crooked. From side guides ( long ones, not poles) to self centering rollers, modifications can be made to correct any problem. Often just having a trailer in to deep is the culprit. If you post pics, we can make suggestions to help with this issue.
