Generator AND decent battery bank(s) AND inverter can be reasonable. Genset for ACs, but the inverter can be very useful at other times (e.g., a quiet pot of coffee, TV for the guests while underway, quiet microwave popcorn, etc.).

I think an inverter adds the option of frost-free (110v) refrigeration, too, if that's attractive.

You can solve the genset while boat-shopping, and you can always add an inverter later, should you choose to do so.

It's not uncommon to have more glass-enclosed areas in raised saloons, and interior temps can easily get up in the high 90s or even 100s. The ACs in this case, often set to relatively higher than usual temps when unoccupied (e.g., 82-85F-ish), are usually about humidity control and keeping any wall treatments from peeling... and it also takes a bit of strain off the fridges/freezers.

Valid point. We've learned a lot in the last couple of months of shopping and from this board. Our preferences have shifted to some degree. For example, ...assuming all other things are equal between two boats and they're both sound mechanically and structurally... while a washer-dryer would be nifty, it's far more important to us to have a small freezer with ice-maker. Although a central vac would be nice, lightweight, portable vacuums can be stored anywhere, are far cheaper, and can be used in more places. Considering our needs and goals, a good genset and a water maker are rising to the top of our list.

Re: Wondering why more power boats aren't using solar power to recharge house batteri

As a recent convert to a trawler, I will weigh in. My CSY 44 was a great sailboat, but in the Sea of Cortez, there was usually no wind, or it was directly on the nose, so motoring was required if you wanted to arrive at your anchorage before dark. I had 3 solar panels on the arch, 525 watts, which worked amazingly well to keep my house bank of over 500 AH fully charged at anchor.

Now my new-to-me trawler has several appliances that require the generator to run in order to use them. An electric stove was all the rage in the late 70's, today, not so much. A full-sized 110v fridge/freezer which runs off the inverter, but also requires running the genny twice a day. Then there is the dual AC units. Too much? Sure, but I assure you that when you come aboard for cocktails you will enjoy the room and the comfort of a trawler. I do plan on adding about 1000w of solar soon.

So quit bashing motor boats and making assumptions about folks that you don't know, and apparently, wish to never meet. You'll find that most of us were sailors before, so we all have common interests. BTW, I moved to a trawler to please my wife, and she IS pleased.

Cheers, Bill

Bingo...you nailed it Bill and when Lori and I find a powerboat we like...we don't feel guilty for a moment about living/cruising in comfort either!

Happy Wife...Happy Life.

Agree, no reason to dislike powerboats.

But there is no more reason to need generators on a powerboat than on a sailboat. If desired a powerboat can be as energy efficient as a sailboat.

With the bonus of a fully charged bank when arriving at an anchorage thanks to alternator output.
