[PCW] Hybrid powercats

[Captnlen]

Back in the mid 70's the USF had a conference on sail assisted 
commercial craft. Dick Newick, Myself and 200 others attended with a 
variety of papers, models and some full size working versions.

One craft from the University Engineering Students was a windmill on a 
cat, driving a prop.  Would also go directly to weather.

Only thing wrong was it was stepped at the normal mast step (used a 
sailing cat) and that blade was close to the deck.

This was straight mechanical no electric motors or batteries.

There are lots of options on motorsailor /power multihulls out there 
besides the huge solar panels.
