Frank looked around the room. "That first table there, they gave their table to this group at the bar. These guys are all executives from PepsiCo. If you have a table, you can give it to your friends, your business associates, or to a charity auction. I had Bobby Flay, Michael Romano, a whole bunch of big chefs last week and I didn' t know they're coming. I never know who's coming in. That's what makes it wonderful. It's serendipity. There's no grand design or plan. The only caveat is if you're not going to use your table and no one else is going to use that table, that's when you call me." This was in January, and Frank said, 'Can you come here May 6?' I didn't know anything. So he writes the date on a business card and hands it to me and says, 'Two things just happened: One, you got a reservation at Rao's which is no small deal. Two, you can always get a reservation at Rao's. I love you. [Abbot makes a kissing sound.] Both cheeks." I am married 46 years," he says. "Same woman. She's great. I love my wife. 46 years. Does she come here? No. I don't want her here. When I come here, I work. What am I going to do? Sit with her at the bar? I have people I have to talk to, things I have to do." Just think about what happened while you were here," he tells me, putting his hand on my forearm for emphasis. "You met my tailor. You met Tony Tantillo. You met Tony Abbot." (I met a trio of Tonys, if you include Tony the bartender.) "You met all these people. You met the congressman. You're seeing Rao's." And because it's so bright, which Frank says is because "it adds to the energy of the room," I really am seeing everything.

Different modelling and design criteria will affect the nature of the 'ideal' RAO curves (as plotted graphically) being sought for a particular ship: for example, an ocean cruise liner will have a considerable emphasis placed upon minimizing accelerations to ensure the comfort of the passengers, while the stability concerns for a naval warship will be concentrated upon making the ship an effective weapons platform. There's only one table for two in the restaurant. "And if you're willing to wait, I'll feed you at that deuce," Pellegrino says. A surge force RAO of 300 kN/m in a wave of height 6m (and hence wave amplitude 3m) means that a vessel experiences a surge force varying harmonically between -900kN and +900kN over each wave cycle; a pitch moment RAO of 1e6 kN.m/m in the same wave means that the vessel experiences a moment about the y axis varying from -3e6 kN.m to +3e6 kN.m.

Again, OrcaFlex allows a range of options. In the old days, Abbot says, Frank used to open the reservation book on a quarterly basis and when he came by to get his table assignment, Donald Trump was waiting in line outside the door with other regulars.

It's 10:20 p.m. We've been here since 7:45, but the hours have gone by in a flash and I have no desire to give up my bar stool and leave the center of all the action.RAOs are effectively transfer functions used to determine the effect that a sea state will have upon the motion of a ship through the water, and therefore, for example, whether or not (in the case of cargo vessels) the addition of cargo to the vessel will require measures to be taken to improve stability and prevent the cargo from shifting within the vessel. Generation of extensive RAOs at the design phase allows shipbuilders to determine the modifications to a design that may be required for safety reasons (i.e., to make the design robust and resistant to capsizing or sinking in highly adverse sea conditions) or to improve performance (e.g., improve top speed, fuel consumption, stability in rough seas). RAOs are computed in tandem with the generation of a hydrodynamic database, which is a model of the effects of water pressure upon the ship's hull under a wide variety of flow conditions. Together, the RAOs and hydrodynamic database provide (inasmuch as this is possible within modelling and engineering constraints) certain assurances about the behavior of a proposed ship design. They also allow the designer to dimension the ship or structure so it will hold up to the most extreme sea states it will likely be subjected to (based on sea state statistics). Finding the forces on the ship when it is forced to oscillate in still water conditions. The forces are divided into: Wave load RAOs do not completely define the vessel motion as do displacement RAOs: they merely define the force and moment which a wave exerts on the vessel. OrcaFlex uses these forces and moments, together with any other loads on the vessel and data on the vessel's mass and inertia, to determine the vessel motion from its equation of motion. However, OrcaFlex can accept RAO data using a wide range of different conventions, so you can input your RAO data in its original form and simply tell OrcaFlex what conventions apply to those data.

The system used to define wave direction. In OrcaFlex 0° means waves approaching the vessel from astern and 90° means waves coming from the starboard side, but if a different convention applies to your data then you must allow for this when entering the data. Finding the forces on the ship when it is restrained from motion and subjected to regular waves. The forces acting on the body are: The Diffraction forces, which are pressures that occur due to the disturbances in the water because of a body being present. The RAO is a transfer function that is only defined when the ship motions can be assumed to be linear. The above forces can then be assembled into an equation of motion: I say to my wife, 'I wish I had a Rao's to go to. I wish I had a Rao's to go hang out in, to go sit at the bar and meet wonderful people, and then sit down and have a wonderful meal," he says. I can see why.

The coordinate system used to define vessel motions and, in particular, which direction is positive. That is, whether surge is positive forward or aft, whether heave is positive up or down and whether pitch is positive bow up or bow down. Congressman! Does Hillary have a shot?" Frank asks U.S. Rep. Bill Pascrell, who represents the 9th District of New Jersey and is with a group that was given a table by its regular owner. "Bill is a Democrat like I am," Frank tells me. He points out his picture with Hillary Clinton on the wall, alongside the other photos of celebrities who have dined here. I say I don't think I've ever met a congressman out in the world. "Come here! You'll meet them!" he says.
