My guess is that the D16 Wings are for paraplegic sailors ... very similiar to the set-up that is avialible for the H16. The D16 wings do not appear to increase the leverage/width of the boat to counter-balance the healing forces ....
Also I could see how they could be very helpful to a sailing program for beginner/novice sailors and of course a paraplegic sailor.
