What a bad setup, five feet on either side of you to tied up boats is not good, single inboard or anything! It usually takes two people to "walk" a boat pulling on lines down a dock and keep it straight, assuming there are no tied up boats in your way so you can fend it off the dock (pier). The comment made about getting launched early makes the most sense maybe?! The "pile" is a whole other issue if your boat is "running in gear".
