Other than instruments, VHF, and a DVD movie here and there on a

Running a god sized chart plotter and radar underway can use as much
as 20 to 30 amps of 12 volt power. I stand by my original statement
that outboards are not suitable for serious cruising.
Another gross exaggeration to try and support an unsupportable
premise.
I HAVE a chartplotter and a radar on my sailboat. There is no setting
I could use on them that would come even remotely close to drawing 20
to 30 amps.
See my post Salty, he means amp-hours,,, it's like if I asked you what
kind of gas milage you got on the highway and you said "Oh about 23
gallons".

Amp hours per what time period? His assertions are wild and without
merit. I rarely leave my RADAR in transmit mode full time unless
warranted by the conditions and situation. It spends a lot of time in
standby, and when in transmit, It's usually not cranked up very much.
As long as I can see what's within a mile or two or three of me, I'm
fine. If I'm anywhere near the routes of a high speed ferry, I need to
see farther. That's not often. I may not use 30 amp hours in a WEEK
(or more) of sailing. My outboard and solar panel have no problem
staying ahead of what I use, so Wayne's argument is just plain silly.
In fact, I have to monitor things carefully and turn on interior
lights to bleed off the surplus, so I don't overcharge the batteries
when motorsailing with the outboard running - even at low speeds.
