The Bravo is closer to a tunnel hull than the Funboat by a small insignificant nitpicking amount.
The V shaped support piece for the center rudder attachment looks like it extends deeper into the water on the Bravo than the Funboat, but they look very much the same to me. They both carry distinct separate hulls all the way to the end.

You can see air all the way through on either side of the center on this picture, no dinghy transom.

The Vortex rounds the hulls to more of a dinghy stern at the transom though. This I could see calling a tunnel hull.

At least in the case of our club, calling the Bravo a tunnel hull dinghy might have reduced the controversy in buying them.
