The compensation limits are determined by EU.
In my case i mist my connection with Luftansa and had to spend the night on a bench at the airport,
I got nothing because Luftansa said it was the air traffic control delayed the flight. There were hundreds of people in Frankfurt in a similar situation.
ATC is a favourite excuse of Ryanair as well I believe. But at the end of the day if you don't try, you don't get. Flights are covered by separate legislation btw.
Rumours going around that Yeats is way off completion. ..someone got all the measurements for the accommodation all mixed ...and it's up to a meter off
82cm apparently 
This isn't a new rumour by any stretch. Its what some of us heard (from several independent sources) when the further delays were announced. However I doubt anyone is going to be willing to confirm if it is true. It would certainly account for the large additional delay, and if true wouldn't necessarily mean the 'official' explanation for the delay is totally inaccurate either (quite feasible things might need replaced as a result).
Which brings me nicely to this. Since I've been getting questions about compensation from affected customers of WB YEATS, ULYSSES, and EPSILON I have published a handy guide to the rules on compensation due to delay or cancellation of a ferry crossing. The ferry companies will probably hate me for it, but its nothing they don't bury in their terms and conditions anyway! Posting here as I know a number of concerned passengers read this forum.

They'll need a lot of silicone to fill that gap 
Thanks for the compensation guide.
I suspect it might take a bit more than some silicone lol.
No problem, it was something which was being added to the site anyway, but with the current issues at IF is also topical. At the end of the day if people don't know they can claim, they won't ,and if they don't claim they have no chance of any compensation at all. The ferry companies won't be bending over backwards to make sure they do, thats for sure!
