We always take ours and use them on board and ashore. I have Cobras 14 mile range and 18 mile range. The best ones that I have are the Motorola 25 mile range. All work well on the ship. Although no matter what range you have there is going to be dead spots on the ship. Also no matter what channel you are on there is going to be chatter. As stated you can silence the talk. Another thing to consider is how many watts the radio puts out. The Motorolas that I have puts out 5 watts. That's good. Enjoy your cruise.
