I just thought you guys were missing me so I wanted to jump in a say hi again..

besides, this is the F16 forum and only F16 matters can be discussed here and only by card carrying f16 class members and boat owners... right?? So why are we discussing a half boat anyway?

....well actually the vortex does have 2 daggerboards, probably does have more in common with a cat than a skiff.

some info here: Vortex Info



- are you referring to the F16 or Vortex here? The Vortex is one design as I understand it.

Missing you, nah, we are only too happy to miss your internet musings

To be honest it looks more like a cat that a skiff to me! certainly has shades of the old tunnel hull moths before they were banned by the moth association.

sorry macca that moves you from fail to epic fail, third time lucky?

the twin daggers are the same config that the prototype Capricorn used before that was banned too Obviously a game changing concept.

interesting..
seems to be a cat..

not sure why the picture isnt showing.
One plate per hull.. The case doesn't look like there is any wriggle room for gybing boards.

Always thought the concpt of the Vortex was a cool design but its a heavy little puppy and where are the twin rudders needed when the windward hull starts to lift ( decreasing the available rudder depth ), looked at fairly seriously before deciding on the F16.

The vortex was described as tunnel-hulled and not a cat. Still a lot of clubs in the UK dont permit cats to sail. A vortex however.... Get it?

Ummm.. you are joking...

Unfortunately, no, he's not joking. It's the case especially with inland clubs based on gravel pits and reservoirs.

The Vortex is described as a tunnel hull, the RYA considers it to be a monohull dinghy rather than a cat. Similarly the Laser Fun (which it most emphatically is NOT) is also described as a tunnel hull dinghy. Before the concept was banned, the International Moth Class boasted a couple of tunnel hull designs and they were very successful.

Of all of these, the Vortex is the closest to being a catamaran. I have sailed one in a force 3-4 and it was an absolute hoot!

“Either is an English pronoun, adjective, conjunction and adverb. As a pronoun or adjective it means one, or the other, of two choices.
you can't say either and give three choices!”

I think you missed the “OR” defining the “to promote some self serving agenda” as separate from the two alternatives preceeding.

“which I can only conclude is to either increase your sense of self importance, promote argument simply for the sake of argument, [b]or to promote some self serving agenda.”[/b]

Well put a solid deck on the UK F16 and you can be a "tunnel" hulled craft as well!!

all very silly imho

Darryl, did you ever see the movie.. "The Naked Gun" that statement sound like something Frank or Ed would say...

Ed: Doctors say that Nordberg has a 50/50 chance of living, though there's only a 10 percent chance of that.

loved that film

Stewart, looks like you need a center rudder as well! that would be seriously scary on a windy day.

Can not believe in this day and age people still discriminate against cats.. should be a law against it

that is a very very slim argument.. one rudder and its a tunnel hull.. two and its a cat, irrespective of how many hulls the boat actually has...

The Yvonne have one plate (it is a 50s Cunningham design) yet classed as a cat.. while the open 60s offshore slugs have 2 rudders..
Still we are away from the question my apologies

It's possibly more to do with the one-piece hull moulding with a single joint to the deck moulding. Whether it's a cat or not is irrelevant for sailing purposes. The important thing is that they are accepted a wider number of clubs than 'true' cats.

Fred is putting foils on his rudders on his new C-Cat "ORION".
At the end of this video you can see them.

You can follow the C-Cat action at http://forums.sailinganarchy.com/index.php?showtopic=101656&st=0

Looks like they are more to damp movement at the stern and keep the rig stable rather than resist pitch-poling. Note also the small fence on the rudders around the waterline, to reduce air disturbance around the upper part of the foil.

The KittyKat 12 footer had a solid deck as did the Yvonne.. Yvonnes still have fleets not sure about the kitty. So that are "tunnel" hulls not cats.. *chuckles*

Those foils on Orion look like "Bieker" foils.. Too small to see the profile.. If they are asymmetrical and Beiker style. Their purpose is to extend the aft wave to behind the boat.. Thus tricking the water into "thinking" the hull length is longer than it is.
Theory is "Longer wave = longer hull = faster boat"
