No - you will not get to the ship until very late afternoon at the earliest - it is UK time plus 2 hours and then you will have to check in to the ship etc and then you would have to leave the ship get to a beach etc so there is absolutely no way. Sorry.
I suppose it depends on the flight timing. However my experience has been no - with the time change, journey from airport to port, embarkation procedures etc the arrival day is pretty much taken care of. The only chance would be if you were on a very late flight out on the last day and left the ship very very early - even then it would be very difficult.
