Dropdown Longshaft for Wharram Catamaran

[FAST FRED]

I was hoping to be able to use a ducted prop with a balanced rudder to steer

If the prop and ducting is underwater while attempting to sail , the results will be like sailing with huge buckets towed astern.

The drive unit lifts out of the water for most of its life whilst sailing.Can still charge ets while up.

If you're asking about that leg of mine, yes as the water intake would be in the hulls.

Would you? probably not, no load on an engine is not good for it, and solar would be the go IMHO
