It's all relative, of course... but I have 900 hp to play with

So ONE second (or less) in gear -- in calm conditions -- is enough to kick the stern of the boat about a foot or so in one direction or other.

PO's target 40' powerboat may be similar... or if with gas engines, TWO seconds in gear might be necessary. No throttle, in calm conditions... and this after coming to an almost complete stop, only barely moving.

Cut and paste Capt. Alex's Rule of Thumb at your helm station. Make sure your rudders are in neutral position, then control the boats movement with the shift levers. Throttle down as slow as you can, then try to go slower. Momentum and inertia can work for or against you.
Practice with all your fenders deployed until you gain more confidence. I have lined my slip with old fenders which has saved lots of gelcoat. The wind and tide will always make the docking process challenging but with practice you will be fine.

I would appreciate it if those of you who have transitioned to bigger boats from small boats tell me what it's like, what to expect, and lastly, how long did it take you to learn?
Many 40 footers have a bow thruster. Makes it much easier to control the bow. I have a 40 foot single (former sailor) and the thruster is a great "cheat".
