[C320-list] Power Consumption

[Myron Welch]

Chris,

Here is my "Amp Hour List" that I made last summer using my Link 20. 
This should help you calculate your power usage at any given time.  I 
found it very helpful and hope it works for you.  If this does not 
print out neatly for you, send me your email address and I will 
resend as an attachment.

>Has anyone ever calculated the power consumption for a stock 320?  I

>sail/anchor with the fridge going and not drain the batteries beyond 
>50%.  Or alternatively, how big a battery bank do I need to run the 
>fridge for x number of hours before plugging in or turning on the

>I assume the fridge is the largest drain, but what is next largest?

>Are there any good upgrades to reduce the drains, LED's, Fridge fan?, etc.
