Hi Wesley and welcome to the Forum
My wife and I are also ex yachties who came across to the "dark side".
Oh yes........... you will miss the challenge of extracting the best speed out of a breeze and all the other satisfactions that sailing a boat in its special groove brings but surprisingly you will pretty quickly get the hang of not walking on the side of a hill when underway, not having to climb a ladder to get out on deck, being ably to sit on deck in a deck chair and face any way you want rather than a fixed bench seat, go places that a 2 metre keel wouldn`t let you and on and on.
And lastly (and I am sure it doesn`t apply to you) you will miss that sanctimonious sneer that sailors have when talking to power boaters
Once again welcome
