This is amazing ! What medium did you use ? <| sep |> Of course it ' s an apple commercial <| sep |> huh ? free college education and national health care socialism . like unickknx 865 mentioned , he ' s a social democrat if anything . <| sep |> No autotune or prerecorded crap here . <| sep |> The negative metacentric height resulted in the Seoul fairy disaster as well as countless RORO cargo ship incidents most notably the Cougar Ace and possibly thr Baltic Ace . The ships were all upright and stable with a negative metacentric height . Once they tried to make a turn , suddenly they became sideways and stable with a positive metacentric height . It is correct that cruise ships opt for a lower metacentric height which does reduce stability some but creates a longer roll period which is more comfortable for passengers .
