Wife and I made the switch 3 years ago. It's good and bad. Nice to be able to get places in hours instead of days, but now (for me anyway) it's more about getting there than the joy of the travel. There is not much to do once you plot the course and set the autopilot except keep a watch for other boats and lobster pots, etc, and watch the water go by. Even traveling at a 15 knot cruise can seem slow after a few hours. Quite different than sailing at 7 knots and feeling like you are flying! I don't regret the change and still love boating, but it's just a different type of boating.
