Homework Help: Nautical/Stability/GM

Posted by Mike on Monday, December 17, 2007 at 8:38am.

I have previously understood a ship's GM determined her role period. However I have just read that if weight on the centreline of the ship is moved laterally outwards to the sides of the ship this will slow the ships roll ie. increase its roll period. I understand the GM of the ship will not alter under these circumstances because as the weight is moved laterally the COG will not change.

Comments please.
