Interesting,
using their numbers and the back of an envolope..
if you fitted 2 moth rudder foils upside down to an F16's rudders you'd increase the total drag by about 6% but it would be the equivalent of having another crew member trapping off the transom. This would mean a boat sailing single handed would have a similar top speed to a conventional double hander but maintain it's acceleration advantage.
I've been here before; and firmly believe this to be correct. Loss of job prohibited the build of said boat. Initial discussions were already taking place.
Project shelved.
