Tarzanesque leaps shouldn't be necessary; maneuver the boat close enough to the quay so crew can safely step ashore and either throw the prepared line over the bollard or run it through the cringle and bring it back aboard the boat, leading it outside the lifelines and around a genoa winch. (Lines led directly to a winch will cause an override if the quay is higher than the deck; a lead block solves the problem.) Do this quickly, particularly if it's windy. After the windward line has been secured, deploy the leeward line in the same way. If the lines are looped around bollards, move the onboard, cleated ends to the genoa winches. Use the winches to adjust the lines and your distance to shore, then cleat off. (If you're in a harbor where there's no swell to create chafe, it's preferable to use the same method with bollards as with cringles, running the line around the bollard and back to the boat. Keeping both ends of every line aboard makes departure quicker and easier as no one needs to go ashore to undo lines.) Check your fenders, adjust their positions as necessary, then enjoy your just reward: Drop your gangplank (if you have a steering vane, you can sometimes use it as such), walk ashore, find a nice taverna, and enjoy watching other skippers and crews attempt the maneuver you've just successfully completed.
