There is this external mounted thruster http://www.yachtthruster.com/advantages which claims to have less than 0.05% loss in power, the same as a folding propellor according to their tests. Of course being external it has aesthetic as well as potential failure from collision risks. Its worth a consideration if you are going down this road.
Yeh, not sure I like the idea of something that is basically a hook bolted through the hull in that position. And pricing is not clear but did see one post that suggested $6k USD - if it were £1k (ish) I would be so tempted! Impressive videos.
