I don't disagree about the AP. But it sure was nice to have the anchor windlass.
As my dermatologist keeps burning this or that off my face and ears I think a bimini is real valuable. Radar just scared the crap out of me - ignorance is bliss! Better yet, stay in port when it's foggy. The fancy wind instruments were next to useless - especially when you realize you can calibrate them to read pretty much whatever you like. I like a depth instrument, GPS with a map and a good compass. If you're on the boat in rain, a dodger keeps most of the rain out of the cabin. Hot water is over rated.
I loved the Air Conditioning on my H356. Refrig was good but I can get along with ice. And that could mean less batteries and charging. The charger was good but I never really mastered it. Battery charge was always a worry. I didn't have AIS but it would have been either useful or not - I haven't decided if the noise obscures the useful information.
Music: Wow, things change by the minute. We used my iPod with great success. Then came Satellite Radio which expanded programing. Now Pandora and some stuff you'd need a 13 year old to explain (To me). I have never achieved reliable internet access while at anchor in my favorite places. And, I've quit buying gadgets to achieve access. When I go out I leave that behind. It's a good thing.
Electric winches are good for single handers.
A good swim platform is so necessary.
