It is a shame they stopped that service, although it could get quite rough.
I remember watching a film in the "cinema" which was in the bow. Wind was F7 and it was rather choppy.
It was full at the beginning and less than a quarter full by the end, and not because the film was bad...
Watching motion on the screen whilst swaying side to side is a good test of any drugs (although I didn't take any, being brave or stupid).
