Backing Into a Slip: Master the Stern-To Berth

Coming in bow-first is easy; backing in stern-to is where skippers earn their stripes. The reward is real: a stern-to berth gives you a private boarding platform (step off the transom onto the dock), easy access to the swim ladder, and — in the Mediterranean — the only way to fit into a crowded quay. But reverse breaks the intuition you built earlier: the rudder only bites once water is flowing past it, so a stationary boat won't answer the helm until you have sternway on.

The trick is to make prop walk your friend instead of your enemy. Recall from earlier cards that a right-handed prop in reverse kicks the stern to port. So plan your approach to a slip on your port side: as you back down, prop walk swings the stern neatly toward the dock. Line up wide, get gentle sternway first (so the rudder works), then use short bursts of reverse — each burst adds a little prop-walk nudge — rather than one long throttle push that just accelerates you backward out of control.

Med-mooring (stern-to a quay with no finger docks) adds one more element: you drop an anchor from the bow — typically 4–5 boat-lengths out — as you reverse toward the wall, then pay out chain steadily. The anchor holds your bow off so you don't drift sideways into neighbours, and two stern lines to the quay complete the box. Set the anchor before you're committed; a dragging anchor in a packed harbour is a slow-motion disaster.

Golden rule for all of it: go slow, and use bursts. Reverse gives you far less steering authority than forward, so approach at the slowest speed that still lets the rudder answer, and keep a fender and a crew member ready at the stern.
