Hello!

I have a

Marine Air Systems Passport II aboard my

Hunter 306. I have two resulting questions:

1) I'm trying to find out how many amps it draws from

shore power. The following are the specs, which confuse me a bit:

Set Point Range 60°F to 85°F [15.6 to -29.4° C]

Temperature Range Displayed O°F to 150°F [-17.8 to 65.6° C]

Sensor Accuracy ±2°F at 77°F

Low Voltage Limit 115 volt units 75 VAC

Low Voltage Limit 220 volt units 175 VAC

Low Voltage Processor Reset 60VAC

Line Voltage 115 Through 240 VAC

Hertz 50 or 60 Hz

Fan Output 12 Amps at 220 VAC

Valve or

Heater Output 6 Amps at 220 VAC

Compressor Output 20 Amps at 220 VAC

Minimum / Maximum Operating Temperature 0° F to 180° F

Power

Consumption Less Than 5 Watts

On one hand, the 5W

consumption on the last line makes me thing it draws 5/130=0.04 amps per hour, which seems rather low. On the other hand, if I took the

compressor output of 20 amps at 220V, convert it to W and back to amps at 130V I get 20x220=4400W and 4400W/130 = 33.8 amps, which seems a bit high.

Could anyone have mercy on my brain and explain how much my AC draws in

cooling mode?

2) The reason for this whole thing is that I'm thinking of

docking the

boat at a friends' place in the Patuxent for a few weeks this summer. He's got

shower power, but of the standard 130V/15amp kind that requires a typical NEMA 1-15

plug. If my AC draws anywhere close to that then it's pretty much a non-starter. But if this is feasible, do you think I can simply get a converter pigtail like the following to use my existing

shore power cable:

Marinco 30 Amp Shore Power Pigtail Adapter
All your thoughts (constructive ones) are very much appreciated.

Cheers!

Nico
