Need help with the proper procedure for adjusting a trailer to a
boat. Thinking:
1. Adjust boat height (raise / lower bunk boards until winch cable is
parallel to trailer frame)
2. Adjust tongue weight (boat position front to rear... careful that
no more than eight inches of boat is extending beyond the rear of the
bunks)
3. Adjust 'bow guide' or 'keel support' to 'fit'
4. Adjust 'bow stop' or 'V block' or 'Y stop' to 'fit'

As you can see I'm struggling a little with terminology for the
components.

I've searched for procedures with no luck.. please pass on comments.
