Thanks for the warm welcome and words of wisdom!
Looking back, some "like to haves" are for the initial purchase and will make it to the "projects to do really soon" list if not already installed. These include an anchor windless and an autopilot if not so equipped.
I'm pretty set on diesel engines and my days of going fast in a boat are, ahem, water under the bridge, so to speak. I'd prefer a single screw boat for the efficiency but I'm inclined to have a spare everything if possible, even an engine. Do those who cruise with a single engine trawler typically plan to use a dingy outboard or jury rig the generator for a get home engine?
Thanks for the tips on the motor yachts. Worth a look. And my budget is somewhat flexible but spending too much could definitely interrupt my retirement on occasion.
