I have used docking arms for several years and find them very helpful, particularly when single handed.
They need to be sufficiently long to be clearly visible when the trolley is deep enough to float the boat on and well padded.
With a clearance of not more than one inch on each side once the bow is tied on the boat has to be central on the trolley.
Hope this helps
