hiya we returned from the canaries on indy yesterday and had a really bad crossing going out force 10 gales so there were alot of people sick, the staff placed sick bags around the boat, 4 of us out of 6 were very sick however the other 2 were fine and the crossing coming back over the bay and into southampton was fine, so really it is hard to answer this question.

I O S WAS REALY GOOD CROSSSING THE BAY OF BISCAY COMMING BACK I HAVE CROSSED THAT SEA DOZENS OF TIME AND ITS THE BEST SHIP TO CROSS THAT BAY AS IT CAN GET REALY ROUGH BUT SHE CROSSES IT GREAT JUST PLOUGHS THROUGH, OCEANA WAS FOLLOWING US COMMING BACK AND SHE TOSSED UP AND DOWN

i have travelled across the bay of biscay twice in oct and nov last year onboard boudicca and sea princess (both much smaller than id) it was fine. only time i noticed was at night lying in bed. i often get motion sickness but i was fine.

Friends on her last week - Bay of Biscay like a millpond going out and everyone violently ill on the way back. In short - you can't tell.
