Curvature of the earth's effect on ship building.

**Lake X Kid** · 10-01-2021, 11:34 AM

The curvature of the earth is more than a centimeter over the length of a modern mega-cruise-liner, container ship, or aircraft carrier. Therefore, naval architects have to factor that in when building said ships on dry docks.

A tidbit (that does not apply to Small Craft but of interest), that I was unware of until now.

Am I the only one who's wondering how many 450R's are hanging off the transom?

ALL OF THE 450Rs hahaha! Neat fact!

Along those lines...It is quite a bit easier to launch a satellite east from the equator due to the 3000 MPH the rocket is already moving [along with earth it sits on].

That Dry Dock..... looks flat.......

........like some know the world is..........

that would also depend on where the ship is built as the earth is not round

I’m sure you’re correct but it’s hard to believe that half an inch of ‘hook’ in the hull of an aircraft carrier will effect its handling at high speed?

after a year or so they pull them out flip them over and blueprint the bottom, its green inititive to save fuel..

Looks like the USS JFK CVN-79

That's impossible! The earth is flat!!!

(just kidding, seriously)

**powerabout** · 10-04-2021, 06:00 AM

its so heavy and fast its built with a hook to keep it on the planet

True except the bunch of "Dips" in Washington DC....

You'd think they would just pour the concrete that the ship is being built on, flat and level from one end to the other. Laser levels don't bend with the curvature of the Earth.
