You might raise a lot of eyebrows in actual practice, but every mooring field gives one opportunities to practice ( even in one's mind) with bow thrust and prop walk and reverse thrust.

Just for instance, say you'd like to raft up with a boat already moored. How would you approach ? Which side ? If the boat was anchored fore and aft, and not subject to windage ( but YOU are under weigh and therefore subject to windage, current and tide ?) Little steps of thinking through the variables, and the boat response to helm, are necessary before the whole comes together.

Commendations on realizing that you need practice and experience. That realization will likely keep you out of trouble until you ultimately realize yes, you can do it.
