ORIGINAL: thompsonx Perhaps you could cite for us the manufacturer's advertised "maximum speed" for the carl vinson. The forestall has an advertised max speed of 30+ kts. Anecdotally, I have been on the forestall 'forest fire'(mid 1960's) when the skipper announced that we were doing 52 kts. (60mph). Physics... when you math everything out - the maximum speed of how fast you can go is based on the power you can generate in contrast to your displacement speed which is the resistance the displaced water puts on your hull. So with the USS Carl Vinson, with it's water line of 1040 feet and displacement of 113,500 short tons at it's ship's Power (194 mw), the maximum speed is 36.2 Knots. By comparison, in your little story - the CV-59 Forestall with it's 900 foot water line and 60,610 short ton displacement - the power required to achieve 52 knots on that ship is 1,248,903 horse power or 931.681 megawatts. Or more simply said: 500% of the ship's maximum power output. Now there are other conditions at play because the above equation is based on still water and doesn't take wind resistance into play at all... if you where going with a current or tide and with the wind - you could potentially go faster, but that is not because the ship is capable of going faster, but because the water provides less resistance and the wind provides extra thrust.
