What was also interesting, was that the "ships log" claimed that we were 
still doing around 20 knots through the swell, so the stern seemed really 
"dug in". The prevailing sea was three quarters on to the bow and the 
stabilizers were doing a good job. In reality, though I mention slamming, it 
was nothing like a 6/7 we had, stern on in an older conventional drive ship 
(Thomson Destiny / ex Sun Cruises Sunbird/  ex Royal Caribbean Song Of 
America), where passengers were soon banned from the stern, as they were 
becoming airbourn, if they did not hold on (fun!)
