Good Evening Raver-
Speaking from experience here....
Managed to get a fully-serrated Spyderco Delica and a big BM AFO onto a Royal Caribbean Cruise Lines vessel during Spring 1998. The big BM AFO stayed in my luggage the whole time. In the eyes of the security staff, I looked like any other 30+ businessman out on vacation.
The security was pretty thorough for the "carry-on" section of the trip. The reason I say this is because once we were shown to our rooms, I easily could have transferred the BM AFO and carried it around the whole time.
What becomes a pain is when you want to go ashore at the different ports of call. They run you through the metal detectors
each and every time you want to re-board the ship. If you're in port for a few days, the hassle-factor starts to really figure in to the equation.
If and when I have to do it again, I will take the fully-serrated Delica and leave everything else at home, including the slightly more expensive "legal" blades like Mini-AFCK's and similar.
There aren't enough "hiding spaces" in your cabins, and there aren't enough realistic concerns to worry yourself about your expensive, exotic hardware out on the high seas. The staff on these ships are primarily college kids or people looking to roam the globe...not lifelong employees. It would mean nothing to some to take a quick peek in your luggage while you're out playing shuffleboard.
If the ship (God forbid) sinks, something along the lines of a Delica would prove
plenty capable until help arrived.
Just my $.02. Have a great cruise and just remember to go easy on the Midnight Buffets!
