... continuously from the deck and backwards ( dam-breaking -like, but with an initial velocity). Figure 4 shows the case of a water jet overshooting the bulwark and deck and hitting straight into the deckhouse. The latter incident is caused by a particularly steep and energetic random wave event (a freak wave...
