If you are boating in the salt, I would recommend a VHS. Channel 16 is monitored by all Coast Guard and other boaters. Your communication will be longer range, even Seattle Coast Guard will pick you up. Very few salt boaters have CB radios on board. Virtually all salt boats have VHS radios.
The licencing is not enforced. I have never heard of anyone being reprimanded by Coast Guard for not having a licenced radio. They are happy that you actually have one and learned how to properly communicate on them. It is a very important safety equipment. If you ever need help, and believe me you will, it is very good to know that people are listening.
Close in, your cell phone will also work. Program in the emergency numbers and you an also have your cell as a backup.
Good luck. And, be safe out there!
