Anyone seen one of these CBTF boats? The full article is available at:

"Speeds of 20 knots on a sport sailboat? Impossible. A 40-ft. sailboat that beats 70-ft. racing yachts? Not likely.
A yacht that can sail without heeling over, yet go faster than anything its own size? Hard to believe. Well, check
out the DynaFlyer 40 Red Hornetand start believing.
What sort of magic is this? Just remember four letters: CBTF. They stand for "canting ballast, twin foil." It's a
concept that is revolutionizing the yachting world, especially for the mainstream sailor. The DynaFlyer design is
the brainchild of two yacht designers with extensive America's Cup backgrounds, Matt Brown and Bill Burns. What the
pair have done with their CBTF concept is to separate two sailing needs–lateral resistance and stability–and solve
them independently.

The canting ballast is the answer. Their DynaFlyer 40 has no conventional keel. Instead, an 1800-pound lead torpedo
is suspended on a 6-ft. strut made from a high-strength stainless steel billet. Using a cleverly designed hydraulic
system inside the boat, the entire strut and torpedo can be angled as much as 55 degrees to each side. Operated by
buttons in the cockpit, the canting ballast moves quickly: just 12 seconds from lock to lock.

With the ballast in the straight down position and a 10-knot breeze, the DynaFlyer heels about 30 degrees. Push the
control button for a moment, and the boat straightens up to just 10 degrees of heel while the speed quickly
increases from 5.5 knots to 7 knots.

Technical sophistication is one thing, but on-the-water performance is another, and the DynaFlyer 40 has it in
spades. In a 15-knot breeze, the Red Hornet can reach 12 to 13 knots while reaching with spinnaker, which would be
satisfactory speeds for a catamaran. While racing, the Red Hornet has often sailed faster.

The one absolute fact is that a sailboat sailed upright is both faster and more comfortable. As the CBTF philosophy
of "sail flat, sail fast" spreads throughout the sailing universe, it's likely that the image of the sharply heeled
sailboat will one day be just a romantic memory."

Interesting, but what's the advantage over a tri or cat?


I have to confess that my cat can't do this:

The last time we cruised Maine we had a chance to see this boat on the hard in Freeport. Its an awesome boat - she
won the Route de Rhume beating the Class 2 Monohull record by 18 hours.

Another RETARD! Only a brainless twit would view that video and think it meant
anything? Did you notice something you sucker-born-every-minute kind of guy? Did you
see any mast, boom, sails, running rigging or standing rigging? No you didn't and the
thought never even occurred in what passes as your brain that the boat would not
self-right like that in the real world with a sailing rig attached.

Jeff, you are the perfect example of how stupidity gets mainstreamed. And you dare
make fun of the wise-beyond-belief Jax Ashby? You, sir, are no Mensan!
