Re: your comments upon the NCL Salten grounding.  I’m wondering if she was expected, because the photograph shows that a suitable boarding ladder appears to have been left alongside the house for use on such occasions.  The grounding sequence you suggest seems very similar to the ‘on-purpose’ grounding of surplus super tankers and cruise liners for scrapping on the beach in India.  In fact, the theory is the reverse of the centuries old method of launching ships lengthwise or sideways down a ramp into the dock at high water attached to drag chains.  This didn’t always work as planned, as Brunel found on his first try with the Great Eastern.

Turning to the actual grounding, it probably doesn’t help our case by rounding her speed up from 16 to 19kts for ease of mathematics, because an increase of 19% in impact speed leads to a 41% increase in energy to be dissipated, as many a ‘boy racer’ has learned to his cost.  So how do we dissipate the energy sliding up a shallow beach?  There’s: light energy – negligible; sound energy – negligible (nobody woke up); mechanical and heat energy - shunting Norway ????, displacing and raising mud & rock ????, sliding friction over the seabed ????, and raising the vessel against gravity.  All must play a part.  What are readers views upon the various proportions of where the energy went?

1Kt=1.6878 ft sec  =  0.5144 metres sec. 
NCL Salten LxB=135x22m, current draught 7.6m (Vessel Finder) in Norwegian salt water.  You might estimate her mass this way or use published Gross Tonnage of 9990 long tons (Vessel Finder).
Mass of 1cubic metre of sea water = 1024kg
1 long ton = 1016kg

Have fun. DaveP
