Recreational powerboating (well, most sailboats have engines too) has been going through a rapid change. Boat designs have changed, but there are still beautiful traditional designs. I'm talking about power plants and controls.
First, power. Multiple outboards are taking over. Plenty of reasons besides easier service. Oh, another good thing about multiple engines is that you'll never be without an engine. Yes, just one 200 hp Yamaha is costly, and four could buy a house in some places. Jet Drives are a whole nother thing which I know nothing about other than that they are way cool.
Second, controls: Joysticks. For instance, if your 37' boat has 2, 3, or 4 200 hp outboards the computer controls can help you easily go in any damn direction with minimal sea skills. Maybe go 50+ knots too if in a hurry or for the thrill. Magic backing into a slip regardless of wind or current. Just jiggle the thing. It would be nice if cars would parallel park like that.
We're old-fashioned, or old school, salt-water people with a single diesel, a wheel, and a Maine lobster boat hull.
