I don't think I welcomed you in your battery thread. Welcome to TF!
Good luck with your new boat and obtaining the training you need. Is that a single or twin engine? What's the propulsion configuration?
An experienced boat handling instructor tried to teach me to dock his single-screw training boat, about 40', and I (or he?) failed miserably. My wife, however, was much more successful at following his instruction. So there's more to it than just finding someone, and be sure to include Heather in the training sessions. She might do better in training sessions without you around, but that depends.
Practice is the best teacher, but I supposed some minimum level of competence and confidence is required to start that.
