Even Matt Miller from the Hobie Cat Company said above in this thread that the Bravo is a modern version of the 12-foot Hobie Monocat.

And it looks like all three boats have just one rudder in the center. Maybe there are "political" reasons for wanting this type of boat classified as a "monohull"?

How do you determine whether it is a monohull or a multihull? In the case of the Bravo, I think the whole thing is molded as one piece -- so, is it a one-piece multihull, or is it a monohull with an unorthodox shape? Thus, probably, the Bravo's original name of "Monocat."

"Tunnel-hull dinghy" could easily be a euphemism for catamaran. In fact, the "tunnel-hull" description could also be applied to a lot of big cruising catamarans -- just very wide monohulls with a cavity beneath. <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" />

Maybe Laser does not want to be known as making catamarans and they want credit for coming up with this great new design that looks and sails like a catamaran but they claim is a monohull.

Personally, I think this is potentially good, because if Laser is making those boats and calling them monohulls, they will eventually get them into sailing programs at the yacht clubs, which will eventually result in more kids being attracted to all the other forms of catamarans. <img src="http://www.catsailor.com/forums/images/graemlins/laugh.gif" alt="" /> What a great idea! Calling a catamaran a monohull!! <img src="http://www.catsailor.com/forums/images/graemlins/laugh.gif" alt="" />
