My mate went out on a Duncanson 29 and mentioned that it felt unresponsive or strange to steer.
And difficult to maneuver in tight spaces.
I was curious and found that the prop is actually located behind the rudder.
Ant thoughts on this.

I'd have to say it probably makes it unresponsive and strange to steer.
Probably difficult to maneuver in tight spaces too.

Edit: all jokes aside, it does seem like a strange positioning for effectiveness, but it might get the motor under the cockpit sole better, rather than behind the mast somewhere taking up space? I did find some photos with what looked like a prop in the more normal portion between the keel and rudder, but it's too much of a pain to put input photos on Seabreeze rather than just copy/pasting...

Everything is a compromise
great water flow over the prop though
but remember boat was built before marina berths so right berth not so much of a problem
the old duncanson 34 was similar but off set
remember these boat are properly called an auxiliary sloop in the "olden words"

If a folding prop is used there is no cavity drag of the prop cutout. I have seen an article where a US sailor modified his older boat to achieve this outcome in the pursuit of lower drag.

They work well in reverse
