Thank you for your different perspectives. This forced me into specifying the target SORs which I am happy to leave for your scrutiny:
- cruising is going min 10 knots and max 20 knots
- unsophisticated sailing and, when in doubt, motor: thus motoring in the slow parts of the relatively rare cruising distance shunts, in close quarters, in light winds ...
- two motors for redundancy and ease of steering short
- two sails for adjusting course on longer cruising stretches when going over 10 knots (and motors are retracted)
- plain daggerboards where the rudders would have been
So, raising and lowering the outboards will be relatively infrequent, but the motors will be running longer than with real sailing. At first view, attractive are pivotable electric propellers like Rick demonstrated or as are available from the likes of http://www.green-motion.com/site/gallery/?folder=content/Boats/Green-Motion%20FastCat%20sailing/ or Rob's pivotable motorized tender(s)...
And, of course, not letting maintenance of motors slip or forget to fill up.
