Practice makes perfect
May I suggest some practical things. Practice, practice, then practice in a different way.While we obviously need to understand how the boat is going to act when we come into the slip, how many have explored handling your boat away from the dock without the pressure?Try tieing a fender to something to hold it in place, like a brick, small anchor, whatever. Drop it somewhere you can come at it from all angles. Now, practice coming up to it and just kissing it with the bow. Start off coming from the downwind side, stalling the boat into the wind as you touch it. Once you've done this successfully a couple of times, try it coming at it from a beam reach, then downwind. Then try coming up to it by backing up, from all those wind orientations again trying to just touch it with the stern. All this will teach you how your boat will act as it slows down. What really gets you is that as you slow down, you loose control. This is where the anticipation comes in. Gaining experience how you need to anticipate without the pressure of creaming the dock is much easier. Then when you have to slide into the slip, you can do it with that confidence that makes it look easy.Some other simple tips are, have adequate fenders and place them to protect the boat according to the current wind angle/conditions. Also having a prop that backs straight makes life MUCH easier. If not, you just need to anticipate. Oh, don't run the fender over and wrap your prop. You get lots of points off for this one.By the way, this will really pay off when you have to pick up a man overboard. Then you'll appreciate all that work.Happy sailing.
