Just to fill in about Cunard's attempts to clean the hull in the last few days. We were on the Burnie cruise and the email we got has already been published in this thread. Instead of taking a day and two nights to get to Burnie, we raced down there and got in position overnight. However, the wind was 28 knots so we did those holding pattern rectangles for 24 hours. Unfortunately, by then, the wind had been up to 44 knots (a strong gale) so we did get to go to Burnie, the cleaning couldn't be done and we didn't get our OBC or FCC, much to lots of peoples' disappointment.
My sympathy goes out to the passengers due to leave to NZ today.
Let's hope some better methods are found to deal with this recent problem/requirement.
