Are X Bows Just a Fashion?

X bow powercat

Many have called the swept back X bows or America’s Cup Bows simply a fashion. I say they have real advantages. The argument against says that you lose buoyancy as the hull buries. That is true, but you also lose drag. It becomes more wave piercer. And at the moment you lose a few hundred pounds of displacement, you are actively participating in hundreds of thousands of foot pounds of a verb. A few hundred pounds are irrelevant. Now check this out. A link sent to me by Owen Myers. The military often has a big enough budget to research things.

Email Gone

Back. I have several new posts ready for here, but first I have to finish the new Kai Oli Oli power cat bid set. It seems to go on forever.

Most important, Outlook would no longer open email today.

The fix was the Inbox Repair Tool. It simply made every past email vanish. Only yesterday and the weekend were not backed up yet. If you sent me one then, please send again. There were a lot of them.

Powercat Brazil

I just got some nice pics from my friend Luis in Brazil. We collaborated on this 46' powercat. He builds them. Looks pretty nice to me. Its not sinking; that's a wave.

Fury

And its impossible to miss the Fury catamarans in Key West.
I have mixed feelings about Fury Charters in Key West. They are the biggest operation there. I visited the boats and they look very well maintained. They run at least 4 of my 65' , 149 passenger cats. My issue is that they bought one set of plans and bootlegged the rest of the boats. It wasn't money issue. Peter

visited me in his Lear jet. Must be how the 1% see the world.  I do understand it is under new owner now.  All I can do is grumble.

Catamaran Container Ship

Several years ago I was asked to design a sail assisted 235′ container ship. On the webpage it says composite, but it may have to be alloy.

http://www.multihulldesigns.com/designs_other/sp_235cargocat.htm

I am talking to another  group about it now. It would be very easily driven, and have much less draft than usual ships. 

On this cat, displacement would be 864,000 lbs per hull.  Draft 7′ and power to go hull speed 1050 hp per hull.  That speed is 23 knots, but as the hulls are narrower than 1/12, it could easily go much faster.
