Welcome aboard! I don't post much on here, but this forum is an excellent resource and very good at answering questions.
We too came from sailboats. We moved to powerboats when I shattered my elbow at the same time that my daughter was born.
The biggest change is that we can go 7kts for hours at a time, not just for those few minutes where the wind and sails are tuned just right. :-)
For the sailing fix, I'm building a 10' dinghy in my garage that will have a sail rig hooked up. It'll be the main tender for the trawler once complete.
