Having had both, I'd opt for the manual hands down. If you flush while
off
shore power and und sail, the drain on the battery is tremeous...



This is bad advice. The power drain is actually small and Katy does not
know the power setup of the boat at all. If she had it and it drained
her batteries, then she simply didn't know how to configure her house
supply.
An electric head makes plenty of sense if you have set it up correctly.
Our 35s5 has three group 27's and it will be no problem. The best setup
is with boats that have two heads so you can designate one for guests
with the electric.
