Quote - Acadia - I'm off to bed now, you do realise I'll be dreaming about this now, LOL!
If I can think of it I'll let you know, but I'm baffled at the moment to what it is. Can you think of anything else which might give us a clue?

LOL, sorry! 

I can't think of anything else that is distinctive.  All I really recall is the basic plot about going out sailing and getting caught in a bad storm.  Much of what I saw took place in near darkness because of the storm.  I know there were 3 people, one a woman, all on the deck of the boat in the front pointy part of the boat.  They had themselves tied to things so they didn't get washed overboard because of the waves (IE: pails of water being thrown at them). There was lots of rain and wind, and you could see mountainous waves behind them.  The boats movements were not congruent with the waves, nor was the amount of water they were being splashed with, which is why I say the waves were projected on a screen behind the boat.
