The big boat will not sail much different from the small one.
A couple of things though:
1) The sails pull A LOT harder and require more thought and care while handling. You generally can't handle them without a couple of wraps on the winch.
2) You're not going to muscle a 47 footer around the dock like you can a 27 footer.
3) Around the docks under power, slow is pro. Have a bail-out plan in case you need to go around again.
