I cant see how they can not allow you to spread ashes over the side.. Just pack the "ern" in your checked luggage in a regular type container, etc that dosnt raise suspision. Less chance of it being found instead of you carrying it through security. Or does the drug dogs smell for dead ashes as well? Once onboard, Just go up on deck at 3am when nobody is around and dump over the side. I walk the decks late at night, so late, I see all the night shift cleaning going on, usually after 3-4 in morning. Most people are asleep by then.
