Cutwater 28 Electrical Systems

[shieldsfx]

Before going on an extended trip, I would like to calculate the electrical system requirements of the boat as compared to my "normal power consumption" for any given period (day or night).

To do this, I need a list of all DC equipment (make/model/Amperage/Wattage rating for each). This equipment includes the DC lighting, refrig, electronics, bilge pumps, shower pumps, etc. Also, specifics on the Blue Sea system, the solar and the batteries. I assume Cutwater performed a similar analysis when designing the electrical systems of the boat to properly size solar/batteries and other key source/use elements.

With this data as input, I plan to use some rather well known formulas in the sailing community to determine the answer:"just how long can I go without a charge..."

Can you provide these details?

There is a recent thread regarding several of the items on the Ranger and their loads. I am sure most of them are similar to the Cutwater. As an unscientific observation, while using the refrigerator( the biggest power hog) , all LED lighting, using 12 v portable inverters for computers, phones and C-pap machine (for sleep apnea) at night and sunny days in the summer, I am good for three days before I need to either move and charge by engine or pull out the Honda 2000.
