Which quote are you referring to?
"They were wrong. Days before the voyage was to begin, tour operator Yossi Zablocki received a curt message: The ship’s crew refuses to cooperate with the provision of kosher food for the Jewish passengers at any point in the trip. Nothing a frantic Zablocki could suggest would alter their stance. “We simply will not do this,” he was told."
And
"Not only would the crew refuse to dedicate any kosher sections of the kitchen, it said, but they also insisted that no kosher utensils or food with a kosher certification will be available on the ship. “The use of kosher china, pots, frying pans, etc. will not be allowed.” Anything kosher was in effect to be treated as forbidden on the ship. And no rabbi shall enter. "
