Possible Mirror Mk IV prototype sighting

Courtesy Jeff, from earlier sailing adventures, who made this clandestine recording of the new Mk IV Mirror while deep undercover. While details are still very sparse, and heavily suppressed by the ultra-secretive UK Mirror racing association, we have a world scoop on this new advance in the Mirror world. Rumored to be a steel built boat, this represents the most radical design change since the Mirror was first produced.

In many ways shocking, but perhaps the way of the future? You be the judge.
