Do it on a week day
Steve when you and the family want to learn how the boat handles and docks do so on a weekday. Weekdays provide a quiet atmosphere, absent of every overly helpful captain on the dock shouting what to do and when to do it. Take her out and approach an open dock by coming along side but still well off the dock. Get the feel for how much it takes to stop her. See much she'll walk when you apply power in either forward or reverse from a dead stop. She should walk to port in reverse, stbd in forward. Learn how to use prop walk to your advantage. How well can you communicate with the person on the bow? Do you have to shout to be heard? Develop hand signals common to both of you to avoid screaming at each other in tense situations. Take her out in the open and at a just a few knots of speed get a feel for how tight she'll turn. Try backing her up for a couple of hundred feet to see how she moves in reverse, very different than forward that's for sure. Every boat handles differently and you'll need to get used to yours. Once you understand all the nuances of prop walk, how she stops, turns, etc. You'll be much more comfortable in docking skills. If you're able to find a certified training course in your area I'd highly recommend you attend one. I'd also have the wife do the same. Whether you attend the same class or separate will depend on how dominate each of you are. If you'll over shadow your wife have her attend on her own. Classes of this type will teach you boat handling as well as sailing skills. Course generally include how to use dock lines to "spring" or leverage you into and out/away from docks. They are well worth the money. Good luck and enjoy your new "baby".Mike
