A/C, Watermaker, Led's, Fridge, Freezer.

in a couple of years i want to purchase a pdq 36 and have all of the above when on the hook. not much time would be spent at marina's.
is there even a setup that will allow this? would have a decent budget for making it work if its possible.
i understand amp hours and wire size. but what i don't know is the appliance side of things, i have no idea of what kind of appliances are available for livaboards, performance vs energy draw. all that good stuff.
thanks in advance.
Cort.

Everything but the air conditioner are commonly available and run on 12 volt DC the ac is workable however you would need a generator . Still workable but can become a pain in the butt to.

Newhaul puts it pretty well. You can get just about anything you want on a boat that you have in a house: air conditioning, fridge/freezer, even washer dryer, assuming you have the room.

There are a few appliances that you will have to have power at a marina or with a generator. Air conditioning is the main one but washer and dryer also need a lot of power.

Don't see this too often but if for some reason you want electric stove/oven or electric heat that also would take a generator.

That sort of weight on a pdq36 will render it's sailing abilities obsolete!

You hit a point when, while possible, adding too much is no longer feasible.

Wiki only lists the weight the weight of the 7kw model as 220 lbs. That doesn't sound like a whole lot. Just trying to figure this all out.

You can run a 5000BTU AC on solar. Need about 1200 watts and a sunny day.

Remember the Power Wall is just a big battery. That means you still have to charge it and 7Kw is a lot of charging. If you covered the entire deck of the boat with solar it would take days to generate 7kW. Or you can add a diesel generator that weighs another 300-400 lbs

Re: a/c, watermaker, led's, fridge, freezer.

My best advice to you is start now. Start investigating power consumption and electronics consumption as well as battery types and storage.
12 volts versus 24 is a good place to start. Why is 24 volt better then 12 on certain things and not others. Watts versus amps versus volts and what are the differences. knowledge is power and you have time to learn a lot.
Make up lists of items and jott down what their consumption is in amp hours as well as amps and volts. Then you can judge what is the better appliance for what you need on the hook.

Re: a/c, watermaker, led's, fridge, freezer.

Re LED lighting
i was able to replace all nav & cabin lights from LedLights.com
They were most helpful in matching base sizes, bulb type and lumens.

I did the whole job for about $110.00 US their customer support was very helpful in making the correct selection.
make sure you select the right lights especially for the nav & anchor lights to meet the 2 nm visibility requirement.

I wish you could see just a few of the electronic conflagrations resulting from a near total lack of technical knowledge that manifest on some of these vessels from the perspective of an electronics technician. The things that people do which are very often bordering on the comical, can also sadly sometimes be dangerous or escalate an already deteriorating situation to that point. I can tell you from experience that hiring someone to at least render a basic design with specifications including all of the math demonstrating their ability to work accurately with a range of electrical engineering and technology will definitely be in your best interest. They should also be able to train you on how to interpret your own system data and provide troubleshooting steps for emergencies. Think about it.
