The 1981 Carver 3007 I am looking at is obviously stored for the winter and I won't see it again until the spring.

It has the dual shore power option. To satisfy my curiosity, I want to see if anyone else with this size has experience with the dual power. Most 30' docks in my area are single powered. I don't know that I want to go to a 35' dock just to get the dual power. What do most dual powered boats do when only one lead is available?

There is not a genset, it does have dual ac/heat, electric range, microwave, second fridge option, etc.

I am kicking myself in the a55 for not drawing a diagram of the pannel before they put it up for the winter.

Thanks for any insight!

The spec cheet says:
.....Dual 110 VAC 30 AMP dockside wiring w/50' power cord (in addition to standard dockside).....
 
if you want to have dual AC/heat and other comforts, you're going to have a hard time running all that on a single 30amp shore connection. some boats have a selector switch on the panel to allow feeding both sides from one source, others should be able to use a splitter. as long as you watch your loads...

if you plan on spending some time at the dock and not alwasy go reset the dockside breaker, you may need both lines.
 
if it is 120V 50 amp on each side you can use a Y to connect to 240V 50A.
 
With two 120v, 30a inlets on the boat and only one, 120 volt, 30a supply on the dock you have very little choice. You can get a splitter so that both sides of your system are powered, but you will only have a total of 30 amps available. The way the boat is configured, it would seem to want up to 60 amps.
 
Yeah, you need 60 amps to get that power for your boat. Otherwise you're going to be "budgeting" your power as you turn accessories on and off so as not to exceed 30 amps. I know, because at my marina I share a 30 amp line with a buddy who has 2 30 amps on his boat. In other words he gets 30 on one, and 30 minus whatever I use on the other. This is stupid, I know, but the marina hasn't fixed the problem yet. So we're always cursing each other when the breaker trips. Good thing we're good friends...
 
Yes, you can manage a 30 footer on a single 30 amp line but you will have to manage your power.
You can run 2 A/C units and basic electrical needs, but if you want to cook or run a hair dryer, you will have to turn one of those A/C units off. Probably have to turn off your water heater as well.

I used to have a 37' Sedan with one fairly large A/C unit, full size refrig, water heater, stove, etc. We managed fine on 1 - 30 amp line.
 
I have a 1982 Carver 3007 Aft and only use one 30A supply. We budget our power, we only have a single AC compresser/condenser with split evaporators, the compressor pulls about 10 to 12 Amps. We have had no problem with AC and hot water heater running, but we switch off the hot water heater when we cook (3 eye glass top unit) each eye can pull 10A so we budget here too. No problem with AC and cooking, I keep a close eye on the ammeter and the admiral clearly understands our limitations.
However it is on my to do list to get the other 30A supply to the boat.
 
My 325 has dual power. Both Air Conditioners are on one 30A breaker and eveything else is on the second 30A breaker.

My marina charges $100 extra per year for using more than 30A. I am not a cheap-skate, but it seems we are always being gouged by the marina for something, so I guess its the principle of the thing.

And, quite often, when we transient to a different marina, they may only have a single 30A outlet available. This is especially true for municipal marinas.

So last year, I bought a 30A Wye cable, so that I can run both circuits from a single 30A service.

Since I have ammeters on each 30A circuit, I can see how much current is being drawn.

I can run both air conditioners, the fridge, and either the microwave or stove all at once. If I try to run both the microwave and stove at the same time - the breaker at the pedestal pops, and I have to go out on the dock and reset it.

But if both air conditioners are not running at the given point, both microwave and stove will operate. The trick is to watch the ammeters and know when to turn on the various gadgets. Its not a pain for the most part, because both air conditioners rarely run unless we are just getting back from a cruise or arriving for the weekend and the air conditioners have not been running.

On the other hand, I live in Michigan so its not like its Florida hot.
 
My 84 has dual 30 Amp. In actuality, I could run off of one single with the single zoned "aftermarket" cruise air. I believe one of the several previous owners decided not to upgrade the genny so ran a complete seperate 30 amp for AC as all else works off the small 3.5kv Onan. Planning on "rewirin'" next year
 
You don't say how many btu's your dual a/c's are but a good rule of thumb to calculate amperage draw is: 1 amp for each 1K btu plus 1A for pump. i.e. 16K btu plus 9K btu plus pump equals ~ 26 amp draw. That wouldn't leave much to run anything else when both a/c's are running. Just remember; this is just a rule of thumb.
