Acceleration Of Cruise Ship

Ship Design Factors from the Ship Designers

22 Ship Accelerations at the Center of Gravity

221 Surge Acceleration

The longitudinal acceleration due to surge is given by the following:

``` a_s = -\omega^2 \xi_s ```

where:

* `a_s` is the surge acceleration (m/s^2) * `ω` is the wave frequency (rad/s) * `ξ_s` is the surge displacement amplitude (m)

For a given sea condition, ship length makes a big difference in behavior. Small ships suffer from larger motions.
